Rare non-syndromic bilateral maxillary and mandibular permanent canine agenesis.

Oligodontia or absence of teeth such as the Canines is rare and is often accompanied with several other missing teeth. This condition may also be accompanied with morphological and growth related changes in the teeth and the maxillofacial complex. Complete agenesis of the permanent canines in the maxilla and the mandible is extremely rare and occurs in association with syndromic oligodontia. Non-syndromic absence of canines however, is extremely rare and has only been reported twice. Studies have shown that the incidence of missing canines is more in females. This report describes a sporadic case of congenital absence of maxillary and mandibular bilateral canines. The patient reported to the clinic with a chief complaint of crowding and wanted alignment. On intra-oral examination it was observed that the patient had all permanent canines missing with no prior history of extractions, crowding in both the arches and class I molars on both sides. With no other symptoms fixed orthodontic therapy was planned for the patient with premolars substituted for the canines.
