Association Between Trauma From Occlusion And Vitality Of Teeth - A Retrospective Study

Trauma from occlusion can play a role in the initiation and progression of pulp and periradicular inflammation. When the intensity produced by the force of occlusion surpasses the ability of periodontium for resistance and distribution of these forces, occlusal trauma may extend and cause some changes in periodontal ligament, alveolar bone, cementum, and pulp. Therefore, it is capable of affecting the vitality of the tooth. The aim of present study was to evaluate the association of trauma from occlusion and non-vital teeth. A retrospective cross-sectional study was conducted using the patient records from the Department of Conservative Dentistry and Endodontics of a dental hospital from June 2019 until March 2020. Patients diagnosed with trauma from occlusion were chosen and evaluated for the vitality of the tooth. Data was collected and then subjected to statistical analysis. Microsoft Excel 2016 data spreadsheet was used to collect data and later exported to the SPSS software. Among 156 individuals diagnosed with trauma from occlusion, 65%of the teeth were reported to be non-vital. Based on gender, females were found to have trauma from occlusion and associated non-vital teeth when compared to males. Mandibular anteriors found to be most affected teeth in trauma from occlusion incidence. There was a declining frequency of trauma from occlusion occurrence as age increases. The highest distribution was recorded among index age group 26-35 years patients as compared to other age groups. Within the limitation of the present study it can be concluded that trauma from occlusion may or may not affect the vitality of teeth.
