Transmigration is a rare occurrence relating to the movement of a mand
ibular canine across the mid-line of the mandible. Two cases are prese
nted where patients referred for assessment of third molar problems su
bsequently revealed on radiological examination the asymptomatic pheno
menon of transmigration. With dental panoramic radiography becoming mo
re widespread among dental practitioners it is possible that more case
of transmigration will be observed.
