Caudodontia of mandibular 2nd molar with bilateral maxillary canine – premolar transposition - a case report.

Transposition of teeth is a developmental anomaly manifested by a positional interchange of two permanent teeth. It is often associated with hypodontia, peg lateral crowding, severe rotation and malformation like dilaceration and missing teeth, retained teeth and even with impaction which are clinically important for diagnosis as well as treatment plan. However, this case is a deviation from the afore mentioned group of associated anomalies. Surprisingly, in this case bilateral maxillary canine – premolar transposition is associated with idiopathic resorption of the crown of the second mandibular molar. The persistence of only the caudal part of the tooth in such a case merits denoting it as ‘Caudodontia’ by us.
