Prevalence of Temporomandibular Disorders and Assessment of Factors Associated with it - A Retrospective Study

E The temporomandibular joint has many anatomic and functional features that make it one of the most complex joints of the body. Temporomandibular disorders are a complex group of conditions involving the temporomandibular joint, disc or masticatory muscles. This condition causes a physical and psychological debility in the population, as the pain is widespread and causes disability. Patients can also have clicking or grating sounds, limited or asymmetrical jaw movement. Even though it is not a life threatening disease, the quality of life is reduced. The aim of this study was to evaluate the prevalence of temporomandibular disorders and assessment of factors associated with it. A retrospective study was conducted in the Saveetha Dental College. Ethical clearance was obtained from SRB committee, Saveetha Dental College. Data was collected from a total of 86000 patients who visited Saveetha dental college between Jun,2019 to March,2020. Out of this, the data of 69 patients who had pain in the TMJ in this time frame were retrieved. The data obtained was tabulated in SPSS for windows, version 20. Frequencies were analysed. Chi square test was done to analyse association. There is no significant association between type of TMD with age (P=0.342), gender (P=0.950) and dental status (P=0.404) in the present study. Within the limitations of this study, TMD was more predominant in males, disc displacement was more predominant and the most affected age group was between 30-39 years of age.
