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. [ABSTRACT FROM AUTHOR]

The eruption of tooth other than the alveolar arch is called Ectopic Tooth. It is frequently encountered in the maxillary sinus. Facial pain is the most common presentation which is commonly misdiagnosed as chronic sinusitis. We present a case of a 47-year-old lady who was incidentally diagnosed to have an ectopic free lying canine in the maxillary sinus and discuss the various theories mentioned in literature predisposing to this condition.
