Incidence of canine impaction and transmigration in a patient population.

In this study, 4500 consecutive panoramic radiographs were prospectively reviewed. The incidence of canine impaction was found to be 3.58% and the incidence of canine transmigration was 0.31%. There were six maxillary and eight mandibular transmigrant canines. The incidence of impacted canine teeth and transmigration of maxillary and mandibular canines may be more frequent than was previously thought, at least in some populations.
