Obstructive sleep apnea (OSA): A prosthodontic perspective.

The subject of sleep medicine, for dental profession in general and prosthodontists in particular, continue to offer great challenges and opportunities in terms of diagnosis, treatment planning and treatment based on qualitative evidence. Although the role played by the prosthodontists is still in its infancy, there is much to learn and understand in the rapidly evolving field of sleep medicine as the recognition of co-managing patients with sleep disorders by the prosthodontists is fast becoming a reality. This article discusses at length the prosthodontic perspectives of the research in the field of sleep medicine, particularly on obstructive sleep apnea.

Mandibular invasion of squamous cell carcinoma: factors determining surgical resection of mandible using computerized tomography and histopathologic study.

Aim: Carcinoma of the mandibular region can be considered as an important, distinct entity associated with special problems relating to diagnosis, evaluation of extension, planning of treatment, surgical techniques, treatment result and prognosis. The study was aimed to assess the accuracy of computerized tomography in demonstrating mandibular invasion, to assess the role of anatomic structures like cancellous spaces, the inferior alveolar nerve and periodontal spaces in spread of carcinomas in the mandible and to determine the spread of tumour within the mandible and the resection procedure to be carried.

Materials And Methods: 11 mandibular specimens which were resected for squamous cell carcinoma were examined clinically, radiographically and histopathologically.
