Abstract :

Objective:To evaluate the reliability of angular method of localising the position of a impacted maxillary canine on orthopantogram(OPG).

Material and Methods: 20 subjects,7 males and 13 females with a total of 24 impactedcanines were evaluated. The angulation of the canine to the occlusion plane was measured using a panoramic radiograph .The angulation of the canine to the occlusal plane was measured using a panoramic radiograph; if the angulation was greater than 65�, it was presumed that impacted tooth is buccally positioned than a palatally impacted maxillary canine.. This radiographically predicted position is verified by intraoperative position of tooth which is gold standard for comparison.

Result: 70 % of palatal placed canines were located accurately by angular method of localisation as compared to buccal placed impacted teeth which were accurately localised in 30% only.

Conclusion : Angulation method is not reliable in accuratelydetermining the position of impacted teeth.However its usefulness in determining the position of palataly placed teeth is more than that of buccally impacted teeth.
