Most cases of posttraumatic trigeminal neuralgia (PTTN) occur due to extraction of tooth, root canal treatment, and any kind of jaw fracture affecting the crown -root of a tooth. Aims: The aims of this study are to know the prevalence of PTTN in dental outpatient department (OPD) and to know the relation between traumatic dental extraction of teeth and occurrence of PTTN. Settings and Design: An institutional observational study. Methods and Material: The study was conducted during November 2018 to May 2019 and patients from dental OPD were selected based on the criteria of inclusion and exclusion factors.
