Introduction: The aim of this study was to identify the prevalence of ectopically erupting canine in pre-adolescent patients reporting to the Dental Outpatients Department (OPD) at Children Hospital, Pakistan Institute of Medical Sciences (PIMS) which is a primary care dental setup, using orthopantomogram (OPG) radiographs. Study design: Cross-sectional design.

Patients with missing canines on clinical examination based on Bishara’s criteria clinical signs, were referred to the Radiology department for OPG to confirm displacement from normal path of eruption. On the OPG, the image of the canine was analyzed.

Results: The studied sample consisted of 1000 patients with 33% males and 67% females. The age range of subjects was between 10 years to 13.5 years with a median age of 11.0 years. There were a total of 131 cases of ectopically erupting canine. In these cases, 37 were on the right, 78 on the left and 16 were bilateral. In females, there were 74 cases with 9 bilateral, 23 on the right and 42 on the left. As for males, a total of 57 cases, 7 bilateral, 14 on the right and 3336 on the left side.
