Background: Maxillary canine impaction is complex in its etiology, localization, response to preventive treatments,and prediction. The present study was conducted to predict canine impaction using OPG. Materials & Methods: The present study was conducted in the department of orthodontics on 60 patients with impacted canines. In all patients, OPG was taken with Kodak machine following standardized radiographic technique. To determinethe angular measurements, a reference line wasneeded. Angulation as a predictor of eruption afterextraction of the deciduous canine was measured previouslyvia a midline constructed from the perpendicularto the central incisors, and to a midline constructedfrom the mandibular central incisorinterproximal contact to the maxillary incisor interproximal contact. Results: Out of 60  patients, males were 22 and females were 38. The difference was significant (P- 0.01). As measured on OPG, the mean angle was 64.00, median was 62.04, S.D was 11.12, minimum value was 42.04 and maximum was 85.01. 7 impactions were seen in sector I, 20 in II, 25 in III and 30 in IV. The difference was significant (P< 0.05). Conclusion: Canine impaction is a common phenomenon. The usefulness of OPG in prediction of impaction of canine is widely accepted.
