Unusual intrabony transmigration of mandibular canine: case series (report of 4 cases)

Vivek Muljibhai Tarsariya et al. BMJ Case Rep. .

Abstract

Intrabony cross arch migration (transmigration) of impacted teeth is a very rare dental anomaly. Transmigration is commonly seen in permanent dentition of the lower jaw. The tooth most commonly involved is the mandibular canine. The prevalence of transmigrated canine has been found to be only 0.14-0.31%. Transmigration of the canine most frequently occurs in a mesial direction resulting in migration across the mandibular symphysis to the opposite side of the dental arch. We report a case series (4 cases) of rare transmigration of mandibular canines and emphasise the need to use panoramic radiography in cases presenting with either over retained deciduous canines and/or missing permanent canines. We also propose a newer modification to the present classification of transmigration for one of these cases as the present classification does not include all the entities.
