Abstract

Context: The trigeminal nerve is a mixed nerve performing both sensory and motor functions and supplies the orbit, the maxilla and the mandible, any trauma whether accidental or iatrogenic are the common cause of trigeminal neuropathy. 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. Statistical Analysis Used: Data collected were analyzed using the Statistical Package for Social Sciences (SPSS) software version 17 using descriptive frequency method. Results are represented as frequency and percentages. Results: The total new cases reported to the dental OPD were 8280 patients, out of those 129 patients of PTTN were recorded. In this study, the prevalence of PTTN patients was 1.55% and the males were more affected than female. Conclusions: PTTN is most often secondary to iatrogenic trauma during dental extractions and other orodental surgical procedures performed in oral cavity with localized sensory defects to inferior alveolar nerve, lingual nerve, and branches of maxillary nerves.
