Transmigration of permanent mandibular canines.

Transmigration is a rare occurrence relating to the movement of a mandibular canine across the mid-line of the mandible. Two cases are presented where patients referred for assessment of third molar problems subsequently revealed on radiological examination the asymptomatic phenomenon of transmigration. With dental panoramic radiography becoming more widespread among dental practitioners it is possible that more cases of transmigration will be observed.
