An Evaluation of the Relation Between Variation in Arch Forms and Relative Parallelism of the Occlusal Plane to the Line Joining the Inferior Border of Ala of the Nose With Different Tragal Levels of the Ear in Dentulous Subjects: An In Vivo Study.

Introduction The purpose of this study was to evaluate which of the three positions on the tragus (superior, middle, and inferior), when connected to the inferior border of the ala of the nose, was the most parallel to the natural occlusal plane in dentate patients, to correlate the level of the naturally existing occlusal plane with the ala-tragal line when the tragus was divided into three portions (superior, middle, and inferior), and to determine which position in the tragus occlusal plane is the most parallel. The study also evaluated the correlation between the variation of arch forms and the relative parallelism of the occlusal plane to the ala-tragal line at different tragal levels. Methods This study included 1405 subjects between the ages of 18 and 35 years.

A Study to Assess the Bond Strength of Acrylic Teeth With Different Retentive Features.

Background And Aim: Flexible denture base has been gaining attention as a denture base material because of its toxicological safety, comfort, and enhanced aesthetics. Debonding of acrylic teeth from the flexible denture base material has posed a great problem to the clinician and patient. This study aimed at comparing the bond strength between flexible denture base with acrylic teeth having different mechanical modifications.

A Novel Design Modification to Improve Flexural Strength of Zirconia Framework: A Comparative Experimental Study.

Aim: Zirconia-based restoration is successfully replacing metal ceramic restorations in posterior areas. Although higher mechanical properties of zirconia, their use in compromised situation is questionable. Hence, there is a need to modify the design which to strengthen the framework.

Hearing Assessment of Dental Personnel: A Cross-sectional Exploratory Study.

Aim: Dental professionals are prone to have hearing impairment due to prolonged exposure of noise in dental college. The aim of the study was to assess the hearing ability of dental personnel working in Yenepoya Deemed to be University, Mangaluru, Karnataka, India.

Materials And Methods: A cross-sectional exploratory study was conducted on 60 subjects (30 male and 30 female).

Influence of Aerated Drink, Mouthwash, and Simulated Gastric Acid on the Surface Roughness of Dental Ceramics: A Comparative Study.

Background: Dental ceramics are known for their natural appearance and their durable chemical and optical properties, and their uses mainly reflect their excellent aesthetic properties, biocompatibility and resistance to wear. In addition, dental ceramics are considered to be chemically inert restorative material with large differences in the chemical compositions and microstructures. Although ceramics exhibit excellent physical properties and biocompatibility, the oral environment presents a series of external factors that affect its physical and mechanical properties in its long term function.

Evaluation of Wettability of Three Saliva Substitutes on Heat-polymerized Acrylic Resin-An Study.

Aim: The aim of the present study was to evaluate the wettability of three saliva substitutes on heat-polymerized acrylic resin.

Materials And Methods: Heat-cured acrylic resins 150 were made and divided into three groups containing 50 samples each, i.e.

An Study to Compare and Evaluate the Correlation of the Facial Measurements with the Combined Mesiodistal Width of the Maxillary Anterior Teeth between Males and Females.

Aim: The aim of this study was to compare and evaluate the correlation of the facial measurements (interalar, intercommissural, intercanthal, and interpupillary distance) with the combined mesiodistal width of the maxillary anterior teeth between males and females.

Objectives: The objectives of this study were: (a) To evaluate the correlation of the facial measurements (interalar, intercommissural, intercanthal, and interpupillary distance) and combined mesiodistal width of maxillary anterior teeth. (b) To compare the correlation of the facial measurements (interalar, intercommissural, intercanthal, and interpupillary distance) with the combined mesiodistal width of maxillary anterior teeth between males and females.

Variations in Flexural Strength of Heat-polymerized Acrylic Resin after the Usage of Denture Cleansers.

Objective: The objective of this study was to evaluate and compare changes in the flexural strength of heat-cured denture base resins when treated using denture cleansers.

Study Design: A total of 40 specimens with dimension 65 mm length, 10 mm width, and 3 mm thickness were prepared as per ISO 1567 specification. A total of 10 specimens were immersed in distilled water to be used as control.

Prosthetic management of malpositioned implant using custom cast abutment.

Two cases are reported with malpositioned implants. Both the implants were placed 6-7 months back. They had osseointegrated well with the surrounding bone.

Areca nut and its role in oral submucous fibrosis.

Areca nut, commonly called as betel nut or supari, is a fruit of areca catechu palm tree, which is native of South Asia and Pacific Islands. The seed or endosperm is consumed fresh, boiled or after sun drying or curing. Chewing areca nut is thought to have central nervous system stimulating effect and along with this it is known to have salivary stimulating and digestive properties.

Single anterior tooth replacement by a cast lingual loop connector - a conservative approach.

One of the most challenging and complex treatment modality is replacement of single anterior tooth. This can be overcome by different treatment options such as implant-supported restorations as well as conventional porcelain-fused-to-metal and resin-bonded fixed partial dentures. Drifting of teeth into the edentulous area may reduce the available pontic space; whereas a diastema existing before an extraction may result in excessive mesiodistal dimension to the pontic space.
