Assessment and Comparison of the Condylar Guidance by Protrusive Interocclusal Records and Panoramic Radiographic Imaging in Edentulous and Dentulous Individuals

[Year:2018] [Month:January-March] [Volumn:8 ] [Number:1] [Pages:36] [Pages No:10-16][No of Hits : 2348]


ABSTRACT

Aim: To compare the condylar guidance angle obtained by extraoral Gothic arch tracing, protrusive interocclusal records (IORs), and orthopantomogram (OPG) in completely edentulous and dentulous subjects.

Materials and methods: A total of 30 edentulous and 30 dentulous subjects were selected. Conventional steps in the fabrication of complete denture with balanced occlusion were carried out. Extraoral Gothic arch tracing records were obtained from each subject. Protrusive IORs were used to program the Hanau Wide-Vue semiadjustable articulator, to obtain the sagittal condylar guidance angle. The sagittal condylar guidance was determined in 60 subjects by protrusive IORs and facebow transfer. The sagittal outline of the articular eminence and glenoid fossa was traced in panoramic radiographs. The sagittal condylar path inclination was constructed by joining the heights of curvature in the glenoid fossa and the corresponding articular eminence. This was then related to the constructed Frankfurt horizontal plane to determine the radiographic angle of sagittal condylar guidance.

Results: There was statistically significant difference between the sagittal condylar guidance values obtained using extraoral Gothic arch tracing and OPG method (p 0.0237) in edentulous subjects. Statistically significant values were obtained using protrusive records and OPG method (p 0.0237) in dentulous subjects.

Conclusion: The use of OPG to set condylar guidance on the articulator should be taken into consideration for both dentulous and edentulous subjects.

Clinical significance: In clinical practice, the use of IORs following Gothic arch tracing for the programming of semiadjustable articulator may be associated with manual errors. To minimize the errors and to obtain more accurate sagittal condylar guidance values, the use of OPG along with IORs should be considered for programming of the semiadjustable articulator.

Keywords: Articular eminence, Gothic arch tracing, Panoramic radiographs, Protrusive interocclusal registration, Sagittal condylar guidance.

Age Determination in Forensic Odontology

[Year:2017] [Month:January-March] [Volumn:7 ] [Number:1] [Pages:41] [Pages No:21-24][No of Hits : 4960]


ABSTRACT

Age determination by means of assessment of the dentition is an application unique to forensic odontology. This process is especially relevant in those cases in which the rest of the skeletal remains are marred, as the tooth remains intact under adverse circumstances while the rest of the skeleton is obliterated. While the process remains complex, multiple methods have been devised to assess the dental age of an individual.

Keywords: Dental pulp, Incremental lines, Radiographs.

Implants for Auricular Prosthesis

[Year:2017] [Month:January-March] [Volumn:7 ] [Number:1] [Pages:41] [Pages No:25-29][No of Hits : 1543]


ABSTRACT

Implants are wonderful treatment option for auricular defects as it provides a retentive auricular prosthesis. Auricular defects can be rehabilitated by autogenous and prosthodontic methods. Implants provide retention of auricular prosthesis by bar and clip method and magnets. Implant used in craniofacial region differs from the one which is used in the oral cavity. The implants are shorter with flange on the top, which is a unique feature for implants used in craniofacial region. The major challenge in placing the implant is the proximity of various anatomical structures. The implants should be placed 20 mm distance to the center of the external auditory meatus in 8 and 11 o’clock positions for right side of the face and the 1 and 4 o’clock position for left side. Two implants with distance of 15 mm will be sufficient to satisfy the biomechanics. Proper planning and use of implants with retentive aids like magnet, bar, and clip will provide a satisfactory prosthesis.

Keywords: Auricular defects, Craniofacial implants, Ear prosthesis, Implant-supported auricular prosthesis.

Clinical Considerations while increasing Occlusal Vertical Dimension

[Year:2017] [Month:July-September] [Volumn:7 ] [Number:3] [Pages:26] [Pages No:103-107][No of Hits : 1127]


ABSTRACT

A decrease in occlusal vertical dimension (OVD) may result from tooth structure loss and extraction of posterior teeth, and it affects the esthetics, function, comfort, and lower facial height (LFH). Rehabilitation of patients with worn dentitions may require increase in OVD and interarch distance to create space for restorative materials, improve esthetics, and develop physiologic occlusion. It is usually advisable to assess esthetics, function, LFH, and response of the stomatognathic system to increased OVD by means of removable or fixed provisional appliances before definitive treatment. The following case report presents the multitude of factors considered in planning amount of OVD increase keeping in view its impact on LFH and facial esthetics, during rehabilitation of a patient with severely attrided dentition.

Correlation between Intercanthal, Interpupillary, Interalar, and Intercommissural Distance with the Mesiodistal Width of the Maxillary Anteriors: An in vivo Study

[Year:2017] [Month:October-December] [Volumn:7 ] [Number:4] [Pages:23] [Pages No:109-113][No of Hits : 960]


ABSTRACT

Aim: This study was conducted for the selection of artificial teeth for edentulous patients with the help of extraoral facial measurement.

Materials and methods: The intercanthal distance, interpupillary distance, interalar distance, intercommissural distance, and width of maxillary six anteriors from a total of 250 subjects were measured clinically. The measurements were made with the help of a digital caliper. Student’s t-test was used to find the significance of parameters between male and female. Pearson correlation has been used to find the relation of the parameters.

Results: The total mean of 125 male subjects for intercanthal distance, interpupillary distance, interalar distance, intercommissural distance, and intercanine width was 31.58, 62.27, 34.77, 48.87, and 50.22 mm respectively. However, the total mean of 125 female subjects for intercanthal distance, interpupillary distance, interalar distance, intercommissural distance, intercanine width was 30.58, 61.48, 34.58, 48.20, and 49.34 mm respectively. The paired t-test showed highly significant results in relation to intercanthal distance and width of maxillary six anteriors. However, interalar distance was found to be nonsignificant and interpupillary and intercommissural distance was significant.

Conclusion: It can be concluded that although various methods for the selection of teeth are used, the applicability can vary due to the ethnic differences between populations. The multiplication factor for intercanthal distance, interpupillary distance, interalar distance, intercommissural distance was 1.6, 0.8, 1.4, and 1 in order to obtain the mesiodistal width of maxillary six anteriors respectively, in males and females. The values were greater for men than for women. No significant differences were found between sexes with respect to intercanthal distance.

Clinical significance: Although there are ethnic differences between populations, the proportions/relationships of anatomical landmarks to the teeth remain the same, which helps in the selection of artificial teeth for edentulous patients.

Keywords: Interalar distance, Intercanthal distance, Intercommissural distance and width of maxillary six anteriors, Interpupillary distance.

Evaluation of the Correlation between the Vertical Dimension of Occlusion and the Length of the Ear, Nose, and Little Finger: An Anthropometric Study

[Year:2017] [Month:January-March] [Volumn:7 ] [Number:1] [Pages:41] [Pages No:1-7][No of Hits : 934]


ABSTRACT

Introduction: The aim of this study was to find out the anthropometric correlation of vertical dimension of occlusion (VDO) with the length of ear, nose, and little finger in dentate male and female subjects in Karad population, so as to use this correlation to determine VDO in edentulous patients.

Materials and methods: The study was conducted in Krishna Institute of Medical Sciences Deemed University, Karad, India, on 320 dentate subjects (160 males and 160 females) who fulfilled the inclusion criteria. Anthropometric measurements of VDO, length of ear, length of nose, and length of little finger were recorded using a digital vernier caliper. Simple linear regression model was used to develop a prediction formula for VDO using length of ear, nose, and little finger as the independent variable. Correlation between VDO and length of ear, nose, and little finger was studied using Pearson’s correlation test.

Results: Statistical analysis in male and female subjects showed that VDO is significantly different with the length of nose, ear, and little finger. Pearson correlation test showed VDO in males has strong coefficient correlation with the length of the ear (r = 0.500), and strong coefficient correlation with the length of the nose (r = 0.335) in females.

Conclusion: The regression analysis was conducted to formulate the regression equation for determination of VDO in male and female subjects. The study revealed that the length of ear in males [VDO = 25.591 + 0.565 (length of ear)] and the length of nose in females [VDO = 36.933 + 0.353 (length of nose)] are strongly correlated with VDO.

Clinical significance: The regression formulae were formulated for male and female subjects in dentate patients which can be used to determine the VDO in edentulous patients.

Keywords: Anthropometry, Ear length, Little finger length, Nose length, Vertical dimension of occlusion.

[Year:2017] [Month:January-March] [Volumn:7 ] [Number:1] [Pages:41] [Pages No:17-20][No of Hits : 763]


ABSTRACT

Aim: To compare the effect of QMix, a mixture of tetracycline, citric acid, and detergent (MTAD), and ethylenediaminetetracetic acid (EDTA) on the microhardness of the root canal dentin.

Materials and methods: A total of 30 single-rooted teeth were decoronated at 15 mm from the root apex. Root canal instrumentation using step back technique was done and the specimens were split into two halves using diamond disc. These were embedded in acrylic blocks and sent for testing by Vickers hardness test. The other half of the specimens was divided into four groups. Control group: In this, normal saline was used. Group I: MTAD was used. Group II: 17% EDTA was used. Group IV: QMix 2 in 1 (DENTSPLY) was used. The specimens were immersed in test irrigant for 5 minutes in closed glass plates. The tested specimens were sent for Vickers hardness test under 100 gm load for 15 seconds. The post Vickers hardness number readings were recorded and sent for statistical analysis.

Results: Data were analyzed using one-way analysis of variance and least significant difference post hoc test was applied for pairwise comparison. QMix showed significantly less reduction in microhardness than EDTA and QMix: Normal saline > QMix>EDTA>MTAD.

Conclusion: QMix as a root canal irrigant is efficient as it caused least reduction of microhardness of dentin. It has antibacterial properties and is also efficient for smear layer removal.

Keywords: Acid, Detergent, Ethylenediaminetetracetic acid, Microhardness, Mixture of tetracycline, QMix.

Prosthetic Rehabilitation of Velopharyngeal Incompetence

[Year:2017] [Month:April-June] [Volumn:7 ] [Number:2] [Pages:37] [Pages No:71-76][No of Hits : 708]


ABSTRACT

Velopharyngeal (VP) dysfunction takes place when palatopharyngeal valve is unable to perform its own closing due to a lack of tissue or lack of proper movement. Insufficiency induces nasal regurgitation of liquids, hypernasal speech, nasal escape, disarticulations, and impaired speech intelligibility. Treatment options include surgical correction, prosthetic rehabilitation, and speech therapy, though optimal results often require a multidisciplinary approach. This case report describes a novel approach for rehabilitation of a patient with soft palate defect (VP incompetence).

Comparison of Various Cold Sterilization Techniques on Routinely used Carbide Burs and Diamond Points

[Year:2017] [Month:July-September] [Volumn:7 ] [Number:3] [Pages:26] [Pages No:97-102][No of Hits : 663]


ABSTRACT

Aim: The aim of this study is to compare the various cold sterilization techniques for sterilizing dental burs and diamond points by assessing the microbial growth in culture media on them before and after sterilization.

Materials and methods: The following four disinfectants were used: 2% glutaraldehyde, 5.2% sodium hypochlorite, hydrogen peroxide, and 70% ethanol. There were two main groups taken as group I—carbide burs and group II—diamond burs. A total of 48 samples were collected, 12 samples per disinfectant. Each sample has two burs collected from same patient. One acts as control group which means only microbial count was determined without disinfection. The other one would be determined as microbial count before and after disinfection. The microbial assessment was done using brain heart infusion (BHI) broth and counted by plating in chocolate blood agar and MacConkey agar.

Results: The obtained results were statistically analyzed by one-way analysis of variance (ANOVA) test and post hoc test. The results revealed that there was statistically significant difference between sodium hypochlorite and surgical spirit, sodium hypochlorite and hydrogen peroxide. There was no statistically significant difference between sodium hypochlorite and glutaraldehyde.

Conclusion: The results of this study revealed that sodium hypochlorite and glutaraldehyde are most effective than hydrogen peroxide, and surgical spirit is the least effective disinfectant. However, there was clinical significance in level of disinfection of all four disinfectants.

Keywords: Glutaraldehyde, Hydrogen peroxide, Sodium hypochlorite, Surgical spirit.

Technique to stabilize Wax Occlusion Rims following Maxillomandibular Relationship Records

[Year:2017] [Month:October-December] [Volumn:7 ] [Number:4] [Pages:23] [Pages No:114-116][No of Hits : 639]


ABSTRACT

Maxillomandibular relationship (MMR) recorded with the help of wax occlusion rims, with or without an interocclusal recording medium, tends to distort during the mounting procedure under higher room temperature. When the records were required to be transported to the distant laboratories for mounting, maintaining the sealed occlusion rims undistorted is always a concern to the prosthodontist. A simplified technique for stabilizing the MMR records made with wax occlusion rims is described. This technique is easy to perform and no special instruments or materials are required. The records stabilized with this technique remain undistorted till mounting even under high room temperature and can safely be transported to the distant laboratories for mounting.

Keywords: Complete denture, Maxillomandibular relationship record, Occlusion rims.

Analysis and Comparison of Correlation between Camper’s Plane and Natural Occlusal Plane in Normal Dentulous Subjects

[Year:2017] [Month:July-September] [Volumn:7 ] [Number:3] [Pages:26] [Pages No:81-85][No of Hits : 600]


ABSTRACT

Background: Orientation of the occlusal plane is one of the most important clinical procedures in the prosthodontic rehabilitation of edentulous patients but definitions of the ala-tragus line (ATL) causes confusion, because the exact points of reference for this line are not clear.

Aim: The aim of this study was to corroborate a correlation between Camper’s plane and natural occlusal plane in normal dentulous subjects and to ascertain the most relevant posterior reference point for establishing Camper’s plane.

Materials and methods: In this study, 40 subjects with complete natural dentition and Angel’s Class I occlusal relationship were selected. The subjects were photographed in sitting erect posture with head unsupported while clenching on a fox plane. The angles between the following lines were measured using digital screen protractor, the occlusal plane and Ala to superior border of tragus, the occlusal plane and Ala to middle border of tragus, as well as occlusal plane and Ala to inferior border of tragus. Descriptive statistics, one sample t-test and, independent t-test were done to analyze the data.

Results: There was no parallelism between the occlusal plane and ATL with three different posterior ends and one sample t-test showed that the angles between them were significantly different from zero (p < 0.001). However, the inferior border of the ATL had the lowest mean angle, 1.99° (4.32) and was almost parallel to the occlusal plane.

Conclusion: Ala-tragus line from Ala of the nose to the inferior border of tragus as a posterior reference point can be considered as a reliable occlusal plane for complete denture fabrication.

Rehabilitation of a Patient with Completely Edentulous Maxillary Arch using “All on 4” Concept of Implantation

[Year:2017] [Month:April-June] [Volumn:7 ] [Number:2] [Pages:37] [Pages No:66-70][No of Hits : 584]


ABSTRACT

Treatment options for insufficient ridge morphology includes the use of short implants, vertical ridge augmentation procedures, or cantilever prostheses in completely edentulous patients. Due to the less predictable long-term prognosis associated with the above-mentioned procedures, the “All on 4” technique was proposed for the rehabilitation in edentulous jaws. The All on 4 treatment concept meets the patient requirements with an immediately loaded fixed prosthesis supported by four implants. This article depicts a clinical report in which an “All on 4” implant treatment is done with delayed loading protocol due to inadequate primary stability obtained.

An Appraisal on Occlusal Philosophies in Full-mouth Rehabilitation: A Literature Review

[Year:2016] [Month:October-December] [Volumn:6 ] [Number:4] [Pages:26] [Pages No:89-92][No of Hits : 3275]


ABSTRACT

Restoration of occlusion in patients with mutilated dentition is a challenging situation as every case is unique in itself. There is a great apprehension involved in reconstructing worn-out dentition due to widely divergent opinions regarding the choice of an appropriate occlusal scheme. A critical assessment and subsequent scientific validation of available literature on occlusal philosophies in full-mouth rehabilitation require an understanding of their evolution in the formative years and the subsequent development of effective models for clinical practice. This study overviews the various occlusal concepts/philosophies in fullmouth rehabilitation, which will help the clinician to select an appropriate occlusal scheme for an individual case.

Softening Condition of Impression Compound for Border molding of Removable Dentures

[Year:2016] [Month:April-June] [Volumn:6 ] [Number:2] [Pages:45] [Pages No:37-42][No of Hits : 1217]


ABSTRACT

Objectives: To prepare removable dentures, border molding using an impression compound has been employed for a long time to obtain a denture border morphology harmonized with perioral muscle movement. However, border molding using impression compound is performed following practitioner’s empirical rule. The objective of this study is to clarify the optimum softening conditions of impression compound for border molding, for which we measured the pressure assumed to be loaded on impression compound during border molding.

Materials and methods: The pressure assumed to be loaded on an impression compound during border molding was measured using a tongue pressure-measuring device. Based on the measured pressure, appropriate softening conditions were investigated (softening temperature and water immersion time) for three types of impression compound: Red (Impression compound Red, Kerr, USA), green (Peri Compound, GC, Japan), and pink (Iso Compound, GC, Japan).

Results: The measured pressure was significantly different between those in the oral vestibule in the lower anterior tooth region during tugging the mouth corner, and in the gingivobuccal fold of the lower first molar during large mouth opening. Regarding the impression compound softening condition, red was deformed by all measured muscle pressures after immersion in 60°C water for 30 seconds and 65°C water for 20, 25, and 30 seconds. Green was deformed by all measured muscle pressures after immersion in 60°C water for 30 seconds, and 65°C water for 25 and 30 seconds. In contrast, pink was deformed by all measured muscle pressures after immersion in 55°C water for 25 and 30 seconds.

Conclusion: It was clarified that for border molding, muscle pressures of all regions during the functional movements can be registered using red and green softened by immersion in 60°C water for 30 seconds and pink softened by immersion for 20 seconds.

Keywords: Border molding, Functional movement, Impression compound, Tongue pressure measuring device.

Prosthetic Management of Total Glossectomy Patients

[Year:2016] [Month:July-September] [Volumn:6 ] [Number:3] [Pages:26] [Pages No:66-68][No of Hits : 1087]


ABSTRACT

Background: Total glossectomy impairs various functions of tongue, such as mastication, speech, swallowing, and also results in psychological breach for the patient during social activities. In a glossectomy patient, the new size of the oral cavity often produces a change in the resonance associated with certain sounds. Also, due to the decrease in size and function of the tongue, interruption occurs in articulation patterns between the tongue, the hard and soft palate, and the teeth.

Materials and methods: We performed a review with a bibliographic search in Scopus, Web of Science along with the PubMed/Medline, Google scholar and internet. We included the articles with major contribution toward management of total glossectomy, excluded articles and works about surgical treatments in anatomical locations other than the oral cavity.

Conclusion: To obtain maximum rehabilitation for these patients, the dentist must have a thorough knowledge of the physiologic processes involved in oral functions. The present article is an overview of various objectives and design concepts for rehabilitation of a total glossectomized patient.

Keywords: Glossectomy, Linguoalveolar, Mastication, Neuromuscular, Resonance.

ABSTRACT

Aim: The objective of the study is to evaluate some of the esthetic factors which will determine an attractive smile.

Materials and methods: This study was conducted with 214 students, between the age of 18 and 25 years, from Dharwad SDM College of Dental Sciences with natural dentition and who fulfilled the required criteria; the frontal photograph was taken of each individuals with smile displaying upper anterior teeth as well as gingiva. Each student’s smile was compared, analyzed, and evaluated. Differences between smile types were determined statistically with Z-proportionality test.

Results: Five elements of smile were analyzed. The difference in smile type between men and women was statistically significant. Average smile was the most common with 48.13%, followed by high smile of 37.38%, and low smile was the least common with 14.49%. The downward curvature was the most common with 48.60% followed by straight curvature 42.88% and the lowest common was upward curvature with 8.88%. Straight curvature was the most common followed by parallel curvature and reverse curvature. Totally, 64.95% students showed lower lip touch of the maxillary teeth, and 22.43% showed lower lip not touching the teeth. And, 12.62% showed lower lip slightly covering teeth; 64.95% displayed till 2nd premolar; 32.24% displayed till the first molar; and 2.8% displayed till canine.

Conclusion: The average smile was the most common with downward curvature, straight maxillary incisal curve with the lower lip, maxillary anterior teeth not touching the lower lip, and a number of teeth displayed till the second premolar. Smile analysis must be assessed in association with the face in order to define esthetic rehabilitation of smile. It will give guidelines for restoration of esthetics in anterior.

Prosthetic Rehabilitation of a partially Amputated Finger using a Silicone Prosthesis

[Year:2016] [Month:January-March] [Volumn:6 ] [Number:1] [Pages:23] [Pages No:10-13][No of Hits : 896]


ABSTRACT

Amputation of a finger will have considerable functional and psychological impact on an individual. Although prosthetic rehabilitation incorporating implants is considered an ideal treatment option, the patient may not give consent due to apprehension toward surgical procedures. The ideal prosthesis should replace the missing part of the finger so precisely that it would not draw the attention of the observer. Fabrication of such a prosthesis will require great technical and artistic expertise. This paper presents a case of prosthetic rehabilitation of an amputated finger using a silicone finger prosthesis.

Keywords: Amputation, Finger prosthesis, Prosthetic finger, Silicone.

Awareness among Patients regarding Dental Implants as a Treatment Option for replacing Missing Teeth in Melmaruvathur Population

[Year:2016] [Month:January-March] [Volumn:6 ] [Number:1] [Pages:23] [Pages No:6-9][No of Hits : 801]


ABSTRACT

Background: Treatment with dental implants has become increasingly important in the range of prosthodontic treatment. Significant improvements in oral rehabilitation particularly in edentulous individuals have been seen. In Adhiparasakthi Dental College, Melmaruvathur, a survey was made to evaluate awareness among patients for dental implants, their level of knowledge, and attitude toward replacement of missing teeth by dental implants.

Materials and methods: A survey of 480 people was conducted through a printed questionnaire and completed by willing respondents. The questionnaires were prepared in English and Tamil language to enable better understanding and completion.

Results: Of the 510 people surveyed, 480 responses were retrieved, of which 331 were aware of dental implant treatment in Melmaruvathur, Tamil Nadu. Among them, 304 respondents were aware that implants could be used for replacement of missing teeth. Most of the respondents stated that dental implants were placed in the jawbone, followed by gums. Only 41% respondents assumed that implants last for a lifetime and only 35% of respondents believe that poor oral hygiene was the most common cause of implant failure.

Conclusion: More dental education programs are needed to improve understanding of the importance of restoration of missing teeth. General implant awareness levels are satisfactory. However, increased awareness of patients for restoration of missing tooth with dental implants is necessary. Dental education programs with special emphasis on advantages, treatment, maintenance, and postoperative care of dental implant therapy are needed. More than two-thirds of the surveyed population is interested in knowing about and being treated with dental implants.

Dimensional Accuracy of Multiple Pour Cast from Different Elastomer Impression Techniques

[Year:2016] [Month:July-September] [Volumn:6 ] [Number:3] [Pages:26] [Pages No:51-56][No of Hits : 693]


ABSTRACT

Context: The elastomeric impression material is the most widely used impression material in contemporary dental practice; their accuracy is critical for the outcome of indirect restorations. The accurate duplicate cast obtained from single impression reduces the professional clinical time, patient inconvenience, and extra material cost.

Aim: To compare the accuracy of the cast obtained from various impression methods utilizing elastomer impression materials.

Materials and methods: The stainless steel working cast model assembly consisting of two abutments and one pontic area was fabricated. Two sets of six each custom aluminum trays were fabricated, with 5 mm spacer and 2 mm space. The impression methods evaluated in the study were additional silicone putty reline (two step), heavy-light body (one step), monophase (one step), and polyether (one step). Type IV gypsum casts were poured at intervals of 1, 12, 24, and 48 hours. The resultant cast was measured with a traveling microscope for comparative dimensional accuracy. The data obtained were subjected to analysis of variance test at significance level <0.05.

Results: The die obtained from putty reline two-step impression techniques had the percentage of variation for the height –0.36 to –0.97% with 0.40 to 0.90% increase in diameter. One-step heavy-light body impression dies recorded the increased width by 0.50 to 0.80% and height reduced by – 0.73 to –1.21%. The resultant dies from additional silicone monophase impressions had a percentage of variation for width 1.20% and height by –1.34%. The similar value for width and height for polyether was –1.46% and –1.30% respectively.

Conclusion: Putty reline technique dies had better dimensional accuracy after repeated pour followed by dies from heavy-light body additional silicone impression.

Key message: The multiple pour cast from putty reline elastomeric impressions is clinically acceptable, while cast from polyether was smaller in dimension.

Keywords: Elastomer impression techniques, Impression accuracy, Working cast and dies.

[Year:2016] [Month:July-September] [Volumn:6 ] [Number:3] [Pages:26] [Pages No:57-62][No of Hits : 679]


ABSTRACT

Problem: Prosthetic eyes often cause dryness, irritation, and inflammation of the anophthalmic sockets.

Purpose: To reduce the discomfort caused due to dryness of ocular prosthesis by a custom-made hollow ocular acrylic prosthesis, which is filled with lubricant drops slowly and systemically released into the ophthalmic cavity upon blinking.

Materials and methods: Thirty-eight patients wearing unilateral artificial eye for a period of more than 6 months were evaluated. An innovative customized hollow prosthesis is described, which was incorporated with a hollow reservoir containing a combination of a tear substitute along with cyclosporine A (0.05%) acting as the lubricant. The patients were then evaluated with the help of a questionnaire, regarding the comfort, dryness, soreness, and the ease of use of prosthesis. A self-formulated grading system was used to record the scores.

Results: Postinsertion of this hollow prosthesis, there was a marked reduction in the dryness, irritation, discomfort, and signs of inflammation.

Conclusion: It was concluded that the continuous flow of the lubricant onto the dry prosthetic eye helps in reducing dryness, irritation, soreness, and inflammation.

Clinical implications: A hollow ocular prosthesis that can continuously discharge lubricant onto the dry prosthesis can help in increasing patient’s acceptance and comfort.

Keywords: Hollow ocular prosthesis, Lubricating prosthesis, Maxillofacial prosthesis, Prosthesis for dry eyes.

Gingival Biotype in the Maxillary Esthetic Zone: A Pilot Study comparing Three Noninvasive Assessment Methods

[Year:2016] [Month:October-December] [Volumn:6 ] [Number:4] [Pages:26] [Pages No:85-88][No of Hits : 679]


ABSTRACT

This pilot study aims to compare reliability of visual, probe transparency, and soft tissue cone beam computed tomography (CBCT) methods for estimating gingival biotype in maxillary esthetic zone. This study included 10 patients with indications for dental implant therapy in the esthetic zone of maxilla. Visually, the gingival biotype in the maxillary esthetic zone was examined by two examiners. Subsequently, the gingival sulcus was probed and observed for its transparency, and soft tissue thickness was measured using soft tissue CBCT. A 100% correlation was found between probe transparency and visual inspection. When comparing visual inspection and probe transparency to soft tissue CBCT, a statistical discrepancy of 57.1% was found. However, the p-value of 0.125 indicated a nonsignificant difference. As per our knowledge, this is the first study comparing the reliabilities of these three noninvasive biotype assessments.

Keywords: Biotype, Maxillary esthetic zone, Osseointegrated implants, Probe transparency.

Esthetic Outcome of Emergence Profile in a Single Tooth Implant Restoration

[Year:2016] [Month:April-June] [Volumn:6 ] [Number:2] [Pages:45] [Pages No:43-46][No of Hits : 632]


ABSTRACT

In the past two decades, replacement of missing teeth with implantsupported prostheses has become a widely accepted treatment for oral rehabilitation of partially or fully edentulous patients. With the growing use of implant-supported oral rehabilitation in the partially edentulous patient and single tooth restoration, the emphasis has now changed toward achieving predictable esthetic success, particularly in the maxillary anterior region and patients who may show the peri-implant soft tissue when smiling and speaking. Establishing a soft tissue contour with intact interproximal papillae around implant-retained restoration is challenging, and failure to achieve these harmonious relationships of soft tissue around the implant may lead to unesthetic appearance. In the following case report, the patient presented with an unfavorable tissue contour around an implant restoration. Reshaping of soft tissue was planned. A combination of two surgical techniques was used, which includes a papilla reconstruction and interpositional graft for achieving desired esthetic for a single-stage implant. Following this, sequential molding of marginal gingival tissue was carried out using provisional restoration to obtain an emergence profile.

Keywords: Cast scraping procedure, Emergence profile, Implant positioning.

ABSTRACT

Aim: To present a novel approach for nonsurgical management of large periapical lesion with open apex by using White Portland Cement to create an apical plug leads to substantial periapical healing.

Summary: Radiographic examination in this case indicated previous root canal treated, immature tooth with a wide-open apex and a periapical radiolucency. After cleaning and shaping Triple antibiotic paste was placed for 3 weeks. Hydroxyapatite was mixed with sterile saline & placed beyond the canal apex until with the aim of creating a periapical barrier. WPC powder was then mixed with sterile water, carried inside the canal to create apical plug (4mm) and obturation. The remainder of the canal was filled with thermoplastic gutta-percha. This was followed by post &core and PFM crown. Clinical follow-up of 2 years revealed absence of clinical symptoms and substantial periapical healing.

A Titanium Cast Hollow Definitive Obturator Prosthesis for a Maxillectomy Patient

[Year:2016] [Month:July-September] [Volumn:6 ] [Number:3] [Pages:26] [Pages No:69-72][No of Hits : 585]


ABSTRACT

Oral cancer necessitates the surgical removal of all or part of the maxilla. The extent of surgical resection is dependent on the size, location, and potential behavior of the tumor. The maxillectomy procedure leaves the patient with a defect that compromises of the integrity and function of the oral cavity, leading to hypernasal speech, fluid regurgitation into the nasal cavity, and impaired masticatory function. Rehabilitation of subtotal and total bilateral maxillectomy surgical defects is a complex challenge to the prosthodontist. Prosthetic rehabilitation of the surgical defect with the help of obturator is very important, because the resulting functional deficiencies have a detrimental effect on the quality of life and self-esteem of the patient.

Innovative use of Single-stage Secondary Impression in treating Oral Rigidity due to Submucous Fibrosis

[Year:2016] [Month:January-March] [Volumn:6 ] [Number:1] [Pages:23] [Pages No:14-16][No of Hits : 577]


ABSTRACT

Restricted mouth opening of a patient presents a great challenge in prosthodontic rehabilitation, especially with complete dentures. Making an adequate border molded secondary impression is crucial in the success of such prostheses. Numerous techniques exist for making impressions in cases of microstomia. All of them involve sectional impressions and extraoral reorientation of the segments. Peripheral seal is compromised in these procedures. This article is laid out to explain how preserving border seal by using single-stage impression is by far the best technique found in the Prosthodontic literature to eliminate the cumbersome sectional impression method. A new method of preserving the seal by means of an impression recorded at a single stage is proposed.

Conservative Approach for replacing missing Tooth using Glass Fiber-reinforced Composite

[Year:2016] [Month:April-June] [Volumn:6 ] [Number:2] [Pages:45] [Pages No:47-49][No of Hits : 535]


ABSTRACT

The loss of anterior tooth can be hurtful to the patient both psychologically and socially. In adolescent patients, temporary replacement of teeth can minimize these concerns. Many approaches have been described for this temporary replacement. Adhesively luted, fiber-reinforced retained fixed partial denture (FPD) can be a clinical alternative for the replacement of missing anterior tooth in selective situations. This is an innovative alternative to conventional metal, ceramic restoration. It is especially useful for patients who cannot afford high cost of FPD and cannot devote much time (number of sittings) for the treatment. The main advantage of fiber-reinforced composite fixed prosthesis is conservative cutting of tooth. Structure and chairside fabrication of the bridge using acrylic tooth are less expensive for the patients. The purpose of this clinical study is to evaluate the clinical usefulness of the fiber-reinforced composite FPD. This report describes the clinical treatment of patients using fiber-reinforced composite.

Composite Resin Stamping Technique using a Translucent Hot Melt Adhesive

[Year:2015] [Month:July-September] [Volumn:5 ] [Number:3] [Pages:26] [Pages No:63-67][No of Hits : 3675]


ABSTRACT

Restoring a complex occlusal morphology of the posterior teeth is tremendously difficult when direct composite resin restorative materials are used because carving of the solid polymerized mass is accomplished mechanically using rotary instruments. The preoperative occlusal morphology of the tooth provides for the preparation of an ideal index of the esthetic and functional anatomy in cases where the carious lesion is confined within a shell of undermined yet intact enamel, and is registered using a transparent hot melt adhesive (HMA) material. The registration is then used as an index to reproduce the occlusal morphology in the final incremental restorative layer during the composite resin restoration, which also allows for the photopolymerization of the restoration through the translucent index.

Knowledge and Attitude toward Denture Adhesives: A Survey on Dentists and Complete Denture Wearers

[Year:2015] [Month:July-September] [Volumn:5 ] [Number:3] [Pages:26] [Pages No:74-80][No of Hits : 2126]


ABSTRACT

Aims and objectives: The objective of the study was to investigate the attitude and assess to the knowledge of complete denture wearers and dentists toward denture adhesive and to initiate awareness for the same.

Materials and methods: A questionnaire was mailed to 850 dentists out of which 456 dentists replied. Three hundred and sixty-two complete denture wearers were surveyed with a different questionnaire in the department and were assessed for awareness and usage of denture adhesive.

Results: The results of this survey indicated that 66.89% of dentists used denture adhesives in their practice. Complete denture wearers lack awareness regarding use of denture adhesives as 74.5% of them had never tried denture adhesives. Majority of dentists are also unfamiliar with their beneficial effects.

Conclusion: It should be emphasized that denture adhesives can be considered as a beneficial adjunct to improve fit, comfort, and function of dentures, and psychological security of patients when indicated in schools of dentistry. The knowledge of the patients will always depend on the knowledge of the dentists and how well the dentists educate their patients.

Key message: The outcome of this survey demonstrates that the rate of knowledge of dental practitioners and patients toward denture adhesives has not been in a good situation.

Piezosurgery in Periodontics

[Year:2015] [Month:April-June] [Volumn:5 ] [Number:2] [Pages:31] [Pages No:51-55][No of Hits : 2029]


ABSTRACT

Piezosurgery is a new and innovative method that uses piezoelectric ultrasonic vibrations to perform precise and safe osteotomies. It was first invented by Tomaso Vercelotti to overcome the limitations of traditional instruments in oral bone surgery. Its use was first reported in the field of preprosthetic surgery alveolar crest expansion and sinus grafting. It provides substantial improvement dental/implant surgery, benefiting the surgeon by ease of use and the patient by minimizing surgical trauma and promoting rapid healing. Manual is used to remove small amounts of bone in areas with relatively less dense mineralization. The manual instruments are difficult to control in cortical bone, particularly where precise osteotomies are essential. They are mostly applied for gross cutting of large bone segments. Motor Driven instruments are often used when bone is very dense. Motor driven instruments transform electric or pneumatic energy into mechanical cutting action using the sharpened edge of burs or saw blades. These instruments generate a significant amount of heat in the cutting zone that must be minimized by water irrigation overheating of adjacent tissue may alter or delay the healing response. The reduced rotational speed decreases not only frictional heat but also cutting efficiency. Motorized cutting tools also decrease tactile sensitivity, slower rotational speed necessitates increased manual pressure which increases the macro-vibration of the cutting tool and further diminishes sensitivity. This article discusses about the wide range of application of piezoelectric technique.

The Clinical Application of Platelet Concentrates: A Systematic Meta-analysis

[Year:2015] [Month:January-March] [Volumn:5 ] [Number:1] [Pages:30] [Pages No:21-26][No of Hits : 1176]


ABSTRACT

Background: Autologous plasma rich in platelets is derived blood product whose uses in dentistry dates back to the 1990s and it has been gaining popularity ever since.

Aim: A systematic review of the available literature to determine the efficacy, safety and success of platelet concentrates in physiological systems as well as describing its vigilant use.

Study design and methods: A Medline search with keywords ‘platelet rich plasma dental’ further filtered using Boolean operators (And , Or, Not) and combination of specific keywords as follows: ‘platelet rich fibrin’, ‘platelet rich plasma regenerative’, ‘platelet rich plasma periodontal’, ‘platelet rich plasma extraction’ with a custom range of 10 years was performed, which yielded 88 results out of which 32 were selected based on the inclusion criteria.

Results: Significantly, successful outcomes have been witnessed in the field of osteoregeneration though it has been evidenced that adequate platelet rich plasma (PRP) additives are essential to bear a therapeutic potential. Favoring blood cell adhesion on the root surface optimizing periodontal healing, PRP has also shown positive effect on gingival repair; though controversial facts have also been reported. In the scope of implant dentistry, PRP has also reported greater implant-bone contact when used in both gel or liquid form. Emerging as a possible pulp capping agent along with properties of decreased chances root growth, PRP has successfully completed apexogenesis in cases of pulpotomy.
Research has shown that although clinical results from the comparison of PRP alone vs PRP and resorbable membrane or various graft materials has shown a varied results, additional research in the field is needed.

Conclusion: Platelet rich plasma has shown promising results in the field of regenerative dentistry, with high success rate in implantology, periodontology and oral surgery. Because of conflicting success rates reported in literature further research is warrented.

Clinical implication: Platelet rich fibrin has displayed various features of rapid clinical healing, excellent bone density, less surgical time, less resorption during healing and decreased postoperative pain, as compared to guided bone regeneration procedures. Platelet rich plasma has also shown a myriad of applications ranging from hard tissue regeneration to soft tissue management, stretching across to the field of pediatric dentistry and endodontics.

Effect of Household Denture Cleansers on Color Stability and Tensile Bond Strength of Two Different Heat Polymerized Acrylic Resins

[Year:2015] [Month:October-December] [Volumn:5 ] [Number:4] [Pages:30] [Pages No:95-100][No of Hits : 1167]


ABSTRACT

Aim: Denture cleansers are used not only to clean dentures but also for disinfection of dentures. Among household denture cleansers, bleach (which contains sodium hypochlorite) and vinegar (which contains acetic acid) have been found to be powerful disinfecting agents. The objectives of this in vitro study were to evaluate and compare the color stability and tensile bond strength of Trevalon and Lucitone 199 heat-cured resins after immersing in household denture cleansers like 1% household bleach and 50% vinegar.

Methodology: A total of 48 Trevalon and Lucitone 199 heatcure resin samples respectively were fabricated. The samples were divided into three groups of 16 samples each. They were immersed in 1% bleach, 50% vinegar and water (control) respectively. The samples were alternatively immersed in cleanser and water for 8 hours for 20 days simulating 30 days of use. At the end of 20 days, color stability and tensile strength were assessed with the help of spectro-guide and Instron universal testing machine respectively.

Results: Sodium hypochlorite and vinegar affected the color stability of Lucitone 199 heat-cure acrylic resin. The color of Trevalon heat-cure resin remained unaltered after immersion in both the cleansers. The change in tensile strength of both the resins was not significant after immersion in both the cleansers as compared with water which was used as control group.

Conclusion: This study concludes that for disinfection and cleansing of denture, sodium hypochlorite can be considered as long as the acrylic used is cross linked.

Keywords: Color stability, Denture base resin, Denture cleanser, Sodium hypochlorite, Tensile strength, Vinegar.

Prosthetic Management of Palatally Placed Maxillary Impacted Canine

[Year:2015] [Month:April-June] [Volumn:5 ] [Number:2] [Pages:31] [Pages No:56-59][No of Hits : 1069]


ABSTRACT

Treatment of asymptomatic impacted maxillary canines in adults is inevitable when primary canine becomes lost through extraction or exfoliation or when the impacted tooth becomes symptomatic. Treatment alternatives include an orthodontic procedure to bring the unerupted tooth to the dental arch or prosthetic replacement of the missing tooth. This is an alternative treatment that involves simultaneous placement of implants into extraction sockets of the teeth for replacement of maxillary canine. This treatment modality avoids the need for conventional preparation of teeth as part of prosthetic reconstruction or prolonged orthodontic treatment aimed at bringing the impacted canine to the dental arch.

Keywords: Demineralized freeze-dried bone allograft, Immediate placement of implant, Impacted canine, Implantation with bone augmentation.

[Year:2015] [Month:January-March] [Volumn:5 ] [Number:1] [Pages:30] [Pages No:17-20][No of Hits : 869]


ABSTRACT

An ocular prosthesis which gives attention to the accurate duplication of natural color, contour, size and ocular orientation will provide realism and symmetry for patients who need it. This article describes a simplified technique of converting a stock eye shell into a well-fitting custom ocular prosthesis that requires minimal clinical procedures and simplified laboratory procedures. The color matching of the sclera of the prosthesis was performed using light-cured resin-based stains that are simple to use and give a more predictable and lifelike appearance when compared to the conventional acrylic ‘paint on’ technique.

Keywords: Custom ocular prosthesis, Resin stains, Scleral characterization, Maxillofacial prosthesis.

Combination of Neutral Zone and Flange Techniques during Fabrication of Complete Dentures for a Segmental Mandibulectomy Patient with Restricted Mouth Opening

[Year:2015] [Month:October-December] [Volumn:5 ] [Number:4] [Pages:30] [Pages No:114-117][No of Hits : 815]


ABSTRACT

Oral malignancies originating from or secondarily involving mandible are usually treated by surgical excision and may result in mandibular defect with or without loss of continuity. Surgical resection may lead to loss of buccal and lingual sulci, loss of symmetry of mandibular function, altered mandibular movements and deviation of the residual fragment toward the resected side. Radiation therapy is often given after resection of malignant tumors, which may produce undesirable side effects, like mucositis and mucosal atrophy, trismus, increased susceptibility to irritation and ulceration and reduction in salivary flow. This overall change in anatomy and physiology of oral cavity after segmental mandibular resection presents a restorative challange. This clinical report presents fabrication of complete dentures for a patient who had undergone segmental mandibulectomy and had restricted mouth opening.

Keywords: Complete dentures, Flange technique, Mandibulectomy, Neutral zone.

The Detection of BANA Hydrolysis Activity in Abutment Teeth in Patients with Removable Partial Denture

[Year:2015] [Month:April-June] [Volumn:5 ] [Number:2] [Pages:31] [Pages No:31-37][No of Hits : 800]


ABSTRACT

Purpose: The aim of this study was to detect the presence of N-benzyl-Dl-arginase-2-naphthalamide (BANA) microorganisms in chronic periodontitis of abutment teeth in subjects wearing removable partial dentures (RPDs) by measuring the red complex using BANA-Zyme test.

Materials and methods: Twenty-five subjects (mean age: 59.3 years) with Kennedy class II partially edentulous arch participated in this study. The microbiological record of red complex was done by BANA-Zyme kit and clinical parameters, such as plaque index (PI), gingival index (GI) and probing depth were recorded at abutment teeth in contact with the direct retainer of unilaterally designed RPDs and the corresponding nonabutment teeth on the opposite side.

Results: Mean scores of BANA for the red complex, PI and GI of the abutment teeth were significantly greater than those of the nonabutment teeth (p < 0.01). No significant mean difference in pocket depth (PD) was found between the abutment and nonabutment teeth. Logistic regression analysis revealed that abutment teeth, high scores of PI and a maintenance interval longer than 6 months were significant predictors for positive red complex scores (p < 0.05).

Conclusion: These results suggest that the microbiological risk for periodontitis of abutment teeth is greater than that for nonabutment teeth in RPD wearers.

Cone Beam Computed Tomography: A New Boon and a Ray of Hope to the Endodontist—A Series of Cases

[Year:2015] [Month:October-December] [Volumn:5 ] [Number:4] [Pages:30] [Pages No:101-109][No of Hits : 753]


ABSTRACT

Aim: This article aims to provide comprehensive information related to the cone beam computed tomography (CBCT) as a diagnostic aid and its potential applications in dentistry.

Background: A study was done on 10 different patients with different findings, such as Radix entomolaris, calcifications, vertical root fracture, internal resorption, cystic lesion, perforation, radicular cyst, preparation for endo surgery. These all findings could not be diagnosed by two-dimensional (2D) imaging which were diagnosed with the help of CBCT.

Review results: Cone beam computed tomography is a revolutionary and innovative procedure that has changed the paradigms in the management of various endodontic conditions. Cone beam computed tomography offers speed and versatility to the practitioner and patient alike. Within few minutes of acquiring the scan, the dentist may fully explore the patient’s three-dimensional (3D) image. The image can then be rotated, color-contrasted, and slices can be isolated and further analyzed. With its accurate and high-quality 3D representations, this technology offers tremendous improvements in diagnostic capabilities, eliminating surprises and minimizing the need for exploratory surgery.

Conclusion: Cone beam computed tomography is an invaluable endodontic tool for use before, during, and after treatment CBCT scanning drives diagnostic accuracy, which positively impacts clinical decisions, increases speed of treatment, and improves productivity and patient outcomes. In short, it has provided the greatest advancement in digital imaging over the past decade.

Clinical significance: When used for preoperative assessment, CBCT imaging provides highly detailed information on the entire tooth structure, including the location and number of canals, pulp chamber size and degree of calcification, curvature of root morphology, tooth and root fractures, inflammatory lesions and defects.

Keywords: Cone beam computed tomography, Endodontic diagnosis, Management of endodontic problems, Radiography.

Influence of Different Ceramic Systems on the Polymerization of Dual-cured Resin Cement evaluated Immediately and after 24 Hours: An in vitro Study

[Year:2015] [Month:January-March] [Volumn:5 ] [Number:1] [Pages:30] [Pages No:1-9][No of Hits : 752]


ABSTRACT

Background: To check the influence of different all-ceramic systems on the polymerization of a dual-cured resin cement, evaluated immediately and 24 hours after curing cycle.

Materials and methods: A total of 80 resin cement disk specimens (n = 20) were fabricated by polymerization through lithium disilicate disks (group B), leucite-reinforced disks (group C), zirconia disks (group D) and without an intervening ceramic disk (group A). Each group further consisted of two subgroups (n = 10), t30 and t60 according to two different exposure times of 30 and 60 seconds respectively. Each of the 80 resin disk specimens was evaluated for microhardness (VHN) immediately and after 24 hours, giving us a total of 160 readings. One way analysis of variance (ANOVA) test was used for multiple group comparisons followed by Tukey’s post-hoc for group-wise comparisons.

Results: Direct activation (group A) of the resin cement showed statistically significant higher mean microhardness values as compared to the experimental groups (groups B, C and D), both immediately and after 24 hours. The mean microhardness for immediate postactivation was always inferior to the 24 hours postactivation test for both direct activation and through different ceramics. For immediate testing time, of both the 30 and 60 seconds curing cycle, there was a significant increase in the microhardness of the resin cement disks cured for 60 seconds through the different ceramics (groups B, C and D) and direct light activation (group A). For the 24 hours testing time, of both the 30 and 60 seconds curing cycle, there was a significant increase in the microhardness of the resin cement disks cured for 60 seconds through the different ceramics except for the direct light-activation group.

Conclusion: Ceramic composition affected the polymerization of dual-cured resin cements. Doubling the light irradiation time significantly increased mean microhardness value. Greater degree of conversion leading to an increase in hardness was observed when the resin cement disks were evaluated after 24 hours.

Reattachment of Fractured Mandibular Incisor using Fiber-reinforced Post in a 12-year-old Patient: A 3-year Follow-up

[Year:2015] [Month:July-September] [Volumn:5 ] [Number:3] [Pages:26] [Pages No:86-89][No of Hits : 703]


ABSTRACT

The incidence of coronal fractures from traumatic injuries is high in school children and causes serious functional, esthetic and psychological problems. Dentists are confronted on a regular basis with their management. Reattachment of a fractured fragment, though not a new technique, is gaining interest as a treatment option. This is due to its advantages over other techniques and advancements in adhesive dentistry. This manuscript presents a 3-year follow-up of a case of complicated permanent mandibular central incisor fracture (no cases reported in literature), that was successfully treated by fragment reattachment using a fiber-reinforced post and discusses the factors affecting the success of reattachment technique.

Keywords: Fiber-reinforced post, Reattachment, Trauma.

Microgravity might affect Peri-implant Mucosal Epithelial Cells during Space Flight

[Year:2015] [Month:January-March] [Volumn:5 ] [Number:1] [Pages:30] [Pages No:10-16][No of Hits : 694]


ABSTRACT

Purpose: The effect of microgravity on gingival epithelial cells (GE1) is unknown; thus, we analyzed cell proliferation as well as the gene expression patterns in GE1 cells cultured under simulated microgravity.

Materials and methods: Gingival epithelial cells were seeded and cultured at 10-3 G in a three-dimensional clinostat to simulate microgravity (group CL) or in normal gravity (group C) for 10 days. Cell proliferation was analyzed by counting the numbers of cells. Real-time polymerase chain reaction was performed to amplify the krt 5, krt 13 and involucrin genes. Additionally, total protein was immunoblotted with anti-krt 13 antibody. Statistical analysis (n = 9, three groups repeated three times) was performed (ANOVA, Tukey’s test, p < 0.05).

Results: Cell proliferation was significantly upregulated under microgravity based on the average number of cells. Cell proliferation and differentiation marker expression was significantly increased after culture under simulated microgravity. Western blotting showed intense krt 13 staining under simulated microgravity. The simulated microgravity environment had an accelerating effect on GE1 proliferation and differentiation.

Conclusion: These findings suggest that GE1 cells would be affected by the microgravity environment during space flight. Moreover, these findings also suggest that we could promote regeneration of gingival cells using of a simulated microgravity environment.

Functional Rehabilitation of Mandibular Molar with Separated Instrument and External Root Resorption

[Year:2015] [Month:January-March] [Volumn:5 ] [Number:1] [Pages:30] [Pages No:27-30][No of Hits : 674]


ABSTRACT

Procedural errors like separated instrument have always been a hindrance for successful endodontic therapy. However, it becomes more challenging when there is an added condition of root resorption in the same root in which instrument is separated. Here, we present and discuss such a case where instrument retrieval was unsuccessful and had to restore to surgical techniques like hemisection and extraction of affected root of the tooth followed by prosthetic rehabilitation.

Varying Perception of Smile Esthetics—A Deviation from the Norm: A Pictorial Questionnaire-based Survey

[Year:2015] [Month:July-September] [Volumn:5 ] [Number:3] [Pages:26] [Pages No:68-73][No of Hits : 657]


ABSTRACT

Introduction: Living in a beauty conscious society, the mouth, a focal point of the face, plays a major role in how we perceive ourselves and in the impression we make on the people around us.
Esthetic perception varies from person to person, being influenced by each person’s personal experience and social environment. In the process of providing esthetic treatment for a patient, one should not only rely on one’s eyes and personal perception of beauty, but also be guided by the patient’s desires. Hence, the measurement of the perception of beauty in dentistry is fundamental for providing scientific data that can guide diagnosis and treatment planning.

Aim: This study aims at evaluating the changing trends of esthetic dentistry with the perception of people.

Materials and methods: The study using a visual pictorial questionnaire was conducted among 100 students of Nair Hospital Dental College, Mumbai, Maharashtra, India in February 2013, consequently repeated in October 2013. The scores were averaged and calculated to record the probability prevalence of the same.

Results: A marked shift from the conventional principles of smiles design has been witnessed showing a changing perception of people contrasting to the esthetic norms.

Conclusion: An equal importance needs to be given to the patient’s desire combined with the dentist’s knowledge and experience of esthetics to deliver efficient and appreciable esthetic outcomes.

Keywords: Esthetics, Perception of smile, Restorative dentistry, VAS.
