The 5th cranial nerve i.e. trigeminal nerve is a mixed nerve performing both sensory and motor functions. This nerve supplies the orbit, the maxilla and the mandible, and any trauma whether accidental or iatrogenic is one of the most common causes of trigeminal neuropathy. Most cases of post-traumatic trigeminal neuralgia are the result of oral surgical operations especially extraction of tooth, root canal treatment and any kind of jaw fracture affecting the crown -root of a tooth. The sensory defects are located mainly in territory innervated by Inferior alveolar nerve, Lingual nerve and branches of maxillary nerves. The objectives are to know the prevalence of post- traumatic trigeminal neuralgia in dental OPD, at tertiary care center, Patna. and to know the relation between traumatic dental extraction of teeth and occurrence of post- traumatic trigeminal neuralgia. A retrospective cross-sectional study was done involving 5300 new cases (patients) reported to the Division of Orthodontics, Department of Dentistry, IGIMS, and Patna. The data collected from the record available from dental OPD record from October 2011 to March 2016.The case were selected based on the criteria of inclusion and exclusion factors. The total new cases reported to the dental OPD were 5300 patients, out of those 112 cases of post-traumatic trigeminal neuralgia (PTTTN) were recorded. In this study the prevalence of PTTN case were 2.11%.The female were more affected than male. Post- traumatic trigeminal neuralgia is most often secondary to iatrogenic trauma during dental extractions and other surgical procedures of oral cavity with localized sensory defects to inferior alveolar nerve, lingual nerve and branches of maxillary nerves.
