ABSTRACT Objectives: In our current economy, it is obligatory that the dentists and technicians be cost conscious about the materials they use. Therefore, it would be economically advisable to reuse them. No matter ‘cost’ is always an important factor in selection of alloys, but the physical, chemical and biological properties for a specific clinical situation should always be the first priority. Before a definitive recommendation can be made for repeatedly using non precious metals, carefully researched information should be available. The purpose of this study was to evaluate the effect of reusing a Ni Cr alloy on its ultimate tensile strength, yield strength and modulus of elasticity. Method: Three groups of 12 samples each were prepared. 100% new alloy was used to cast the samples of group A. Group B consisted of samples which were cast using 100% once used alloy, and Group C consisted of samples cast using 100% twice used alloy. The materials were judiciously chosen and the method employed was standardized to produce satisfactory test specimens. All tensile testing was done on a modified tensile test bar of ADA specification no. 14, which was further modified to facilitate sample alignment during investing and reduce the problems associated with castings. Results: The tensile bars were then tested for its properties of Ultimate tensile strength, yield strength (at 0.2% offset) and modulus of elasticity. The results were then subjected to standard statistical analysis. The comparisons of means of ultimate tensile strength, yield strength, modulus of elasticity values of different groups were made using ‘student t test’. It shows a significant reduction in these values if the alloy is reused. Conclusion: The practicality of recasting base metal alloys as an economy measure came under close scrutiny during the investigation.

Ameloblastoma, previously known as adamatinoma, a distinctive benign, locally invasive odontogenic tumor grows slowly and progressively. Among the six histopathological variants, the granular cell type is the rarest form but the most aggressive in terms of recurrence. A patient presented with a recurrent anterior mandibular swelling. The swelling was finally excised and was reported to be granular cell variant

The purpose of this study was to assess the awareness and attitudes of medical students with regard to the subject of Orthodontics. Considering the fact that today's medical students will be tomorrow's medical practitioners, they would probably encounter patients with various malocclusions or dentofacial defects, who would not have an esthetically pleasing profile. Hence it was considered pertinent to assess their level of awareness.This cross sectional study was conducted among the first yearMBBS students at the K.S.Hegde Medical Academy, Mangalore. 132 students participated in the survey. A validated questionnaire was distributed among the students. Descriptive statistics, i.e., number and percentage was used to describe the variables. There was a difference between male and female students' awareness and their attitudes towards orthodontics.While there is scope for conducting similar studies in future, it was concluded in this study that medical students had average awareness of orthodontics as a sub-specialty of dentistry.A basic introduction to dental sub-specialties would help them identify dentofacial problems and make appropriate referrals. Orthodontists for their part could improve their communication skills and allay patient fears about treatment discomfort.

Prosthetic rehabilitation of a partial or total maxillectomy patient with an obturator prosthesis is a predictable intervention to recreate an anatomic barrier between the oral and nasal cavities, and to restore mastication, deglutition, speech and esthetics. The use of a hollow bulb design reduces the weight of the prosthesis and gives better comfort to the patient as the retention, stability and support of the prosthesis is improved. This case report describes fabrication of single piece hollow bulb definitive obturator prosthesis for a patient with left side total maxillectomy

Obstructive sleep apnea is a sleep disorder of airflow at the nose and mouth during sleep. It is apotentially hazardous condition and appropriate treatment should be strongly advised to all OSA patients. Dentist are becoming increasingly aware of the importance of detection and management of obstructive sleep apnea. Mandibular repositioning appliance plays an important role in management of OSA. This articles reviews etiology, clinical features, diagnosis and various treatment options with special reference to oral appliances how snoring can be controlled prosthodontically by different modalities of scientifically defensible
