Abstract
Objectives: The study aimed to evaluate the prevalence and patterns of impacted and transmigrated canine and associated
pathologies in a dental population. Methods: The panoramic radiographs of 5531 patients [1820 (32.9%) male and 3711
(67.1%) female] who attended to several dental clinics between August 2018 and January 2019 were retrospectively
evaluated. The number, position, impaction and transmigration of canine were noted. An impacted canine was diagnosed
to be transmigrated when at least part of its length had crossed the midline. The presence of other coexisting anomalies
was also noted. Results: A total of 388 patients (7.0%) presented with at least one impacted tooth. The most common
impacted canines were in the maxilla among 368 (94.8%) patients, while 51 (13.1%) patients showed impacted canines in
the mandible. About 32 (8.2%) patients showed both co-existed maxillary and mandibular canine impaction, while 126
(32.5%) impacted canines were bilateral either in the maxilla or in the mandible. Transmigrated canine was observed
among 26 (6.7%) of impacted canine patients. Impaction of other teeth was found among 173 (44.6%) patients. Certain
anomalies were co-existed along with canine impaction in 98 (25.3%) patients. Pericoronal radiolucency was the most
common am-ong 84 (21.6%) patients followed by dentigrous cyst among 23 (5.9%) patients. Other anomalies were
supernumerary teeth among 5 (1.3%) patients, and odontoms in only 1 (0.3%) patient. Conclusions: The prevalence of
impacted teeth was high, and there was a predilection for impacted teeth in the maxilla. Pericoronal radiolucency was
commonly seen in relation to the impacted canines followed by dentigrous cyst.
