The Anomalous Mandibular Canine

A small series of cases has been investigated in which the unerupted mandibular canine has crossed the mid-line. The angle that the canine assumes during its developmental period may provide some indication of its subsequent behaviour. It is likely that the migration of the canine commences early, from 8½ years in the present study and 7 years 10 months in the case described by Ando et al (1964). Normal intra-oral radiographs are probably inadequate in the early detection of this condition and in the later stages of migration may lead to the condition escaping undetected.
