Objective: There is limited data available regarding dental arch morphology and its association with Sleep Disordered Breathing (SDB). The objective of the study was to compare the dental arch morphology of patients with Obstructive Sleep Apnoea-Hypopnoea Syndrome (OSAHS) and of those without any symptoms of SDB. Patients/Methods: A total of 600 subjects were included in the study and were divided into two groups of 300 subjects each (390 men and 210 women); Group 1: Patient group; Group 2: Control group. The test and control subjects were well matched for age and gender. A comparative cross-sectional study design was employed and specific measurements were made on dental study models with digital calipers to ensure precise and accurate measurement of anatomic distances. Results: Analyses were able to detect statistically significant changes (P<0.05) in maxillary and mandibular dental arch and alveolar width dimensions. The prevalence of recorded malocclusions in the OSA group in terms of molar/canine relation was also high, with most of the test subjects having an Angle's Class II malocclusion. Conclusions: Indian adults with OSA have a dental arch morphology, which is different from that of normal subjects, of similar age and gender. It is necessary to give due consideration to the evaluation of the dental arch morphology of patients with SDB before the appropriate treatment is offered.

There are a variety of options for use of dental anaesthetics. Anaesthetics can be used on their own or combined for improved effect. More dentists are offering newer types of anaesthesia and sedation in their own offices but the lack of inspection, inadequate training of para dental staff and unavailability of necessary emergency measures in the dental clinics is causing more accidents. A policy to govern the use of anaesthesia in dentistry is an increasingly controversial topic. Anaesthesia awareness among the dentist community leaves a lot to be desired. One reason there has been no urgency for framing a Dental Anaesthesia Policy is because there is very little data related to mishaps attributable to use of anaesthesia in dental practice. Dental practice does not have a systematic or scientific type of reporting to enable practitioners to predict or examine outcomes. When a procedure has adverse results, the dental practitioner is most likely to decide not to try it again or worse, decide to keep the failure to themselves so as not to harm the growth of their practice. An important aim of having a Dental Anaesthesia Policy is to pay adequate attention to the patient once dental anaesthesia is administered and to prioritise medical care, in case of any emergency.

Current literature suggests that tooth fracture post endodontic treatment is a more common complication than an endodontic reinfection. The best way to treat such complication is rehabilitation with complete coverage restoration with or without a foundation restoration. Critical analysis of several in vitro studies suggest that a posterior glass fiber reinforced composite restoration, particularly with glass fiber posts placed horizontally in a bucco-lingual direction improves the fracture resistance significantly. These case reports describe in detail the method of placement of posts horizontally rather than the conventional vertical placement in endodontically treated teeth to strengthen the remaining coronal tooth structure.
