Temporomandibular disorders are a class of degenerative and musculoskeletal conditions associated with morphological and functional deformities. It is prevalent among all age groups causing various symptoms, including pain, discomfort, even limiting the functions. Malocclusion is one of the predisposing factors causing TMJ disorders. Hence the objective of this study was to evaluate the relationship between TMJ disorders and malocclusion. A retrospective study was conducted. Data was collected through reviewing records of 86000 patients visiting a dental hospital in Chennai. A total of 294 patients who had reported with TMJ problems were evaluated. Data such as age, gender, symptoms, associated with TMD, presence of malocclusion, patient's profile were noted. The data collected were analysed statistically through IBM SPSS software. A total of 294 patients reported with TMJ disorders in all age groups from June (2019) to March (2020). TMJ disorders were prevalent more in the age group of 20-40years (57.4%) and more among males (52.58%). About 54.79% of the patients with TMD had malocclusion. In this study, TMJ disorders and malocclusion were significantly associated with each other.

Extractions of molars are one of the frequently performed procedures in a dental clinic and it is associated with innumerable trans operative and post-operative complications, such as edema, trismus, localized alveolar osteitis, pain and surgical site infection. Some authors advocate the use of local and systemic antibiotics to reduce the incidence of these postoperative complications. Despite the risks of allergic reactions among some individuals, toxicity and the development of antibiotic resistant microorganisms, about 50% of dentists routinely prescribe the use of prophylactic antibiotics for this purpose, however the number of antibiotics prescribed vary among dental practitioners. A retrospective study was done among patients visiting the Department of Oral and Maxillofacial Surgery undergoing extraction of first and second mandibular molar and prescribed post-operative antibiotics. The number and group of antibiotics were noted, data were tabulated, and descriptive statistics were performed. Among 1909 patients, about 95% of the patients were prescribed single antibiotic post-extraction, and this was high among young adults, whereas multiple antibiotics were highly opted and prescribed for middle-aged adults.

Lately, people have become more conscious about their physical appearance. Orthodontic treatment has no doubt in providing a significant effect on facial aesthetics. Commonly treated dental and skeletal malocclusion includes class II and class III, skeletal malocclusions might need orthodontic fixed appliance, orthognathic surgery or a combination of both for its correction. The aim of this study is to analyse the prevalence percentage of patients with skeletal malocclusion undergoing orthognathic surgery along with fixed orthodontics. We reviewed and analysed the data of 86000 patients who visited a dental institutional hospital between June 2019 and March 2020. A total of 60 patients were chosen to be included in this retrospective study. They were diagnosed with either class II or class III malocclusions. Socio-demographic and clinical data of all the 60 patients were collected, such as age, gender, type of skeletal malocclusion, treatment suggested and treatment undergone were retrieved from the patient records provided by Saveetha Dental College and Hospitals. This data was tabulated in excel and analysed using SPSS software. Chi-Square test was performed, and the p-value was determined to evaluate the significance of the variables. Among the patients, 51.7% were males with the peak prevalence of reporting for skeletal malocclusion treatment at the age of 10-30 years (85%). Most predominant dental malocclusion being class II division 1 (38.3%) followed by class III(23.3%). Proclination (40%) and crowding (60%) were other common dental alignment issues in the maxillary and mandibular arches, respectively.
