Incidentally Detected Intranasal Supernumerary Tooth: A Case Report

Abstract

Intranasal tooth is a rare type of supernumerary teeth. Its aetiopathogenesis is uncertain but genetic predisposition, trauma and infection are described in previous literatures. It can be either symptomatic or asymptomatic. In our case report, it was asymptomatic which was diagnosed mainly by CT scan as a radiopaque lesion with morphology and attenuation same as that of intraoral tooth. We report a case of an incidental intranasal supernumerary tooth in a 45-year-old male who presented with history of road traffic accident and parasymphyseal fracture of left mandible. This case highlights the rarity of this entity.
