title: Ectopic canine tooth: a rare cause for maxillary antral mucocoele.
abstract: A 40-year-old female presented with a 10 year history of left sided facial pain and occasional purulent nasal discharge, refractory to antibiotics. Dental examination showed 3 missing teeth in left maxilla one of which had no history of extraction. X-ray paranasal sinus showed a bony opacity in the maxillary sinus but nasal endoscopy was normal. C.T. scan revealed a radio-opaque shadow arising from medial wall of left maxillary sinus with a large maxillary mucocoele. Caldwell-Luc procedure was done and an ectopic canine tooth was seen arising from the medial antral wall. Extraction of the tooth with excision of mucocoele resulted in relieving of the symptoms.
