Comparative evaluation of impacted maxillary canine position using panoramic radiograph and CBCT

Abstract

AIM: To correlate labiopalatal position of impacted maxillary canines and evidence of root resorption of permanent incisors in CBCT relative to its position in panoramic radiographs.

MATERIALS AND METHODS: Archived panoramic radiographs and CBCT of 10 patients with impacted maxillary canines were assessed. Labiopalatal position in panoramic radiographs were assessed using sector location and angular measurements and compared to position and evidence of root resorption of adjacent incisors in CBCT. Data was analysed using SPSS version 21.0.

Results: Labially impacted maxillary canines were frequent in sector 1,2,&3 and palatally impacted canines were frequent in sector 5 in PAN. Positive Correlation (r = + 0.468) exists between Panoramic Sectors of Impacted Maxillary Canine and Labio-palatal position in CBCT at significance level of 0.10. Negative Correlation (r =- 0.556) exists with angulation at significance level of 0.10. Root resorption were frequent in panoramic sector 5.

Conclusion: Labio-palatal position of impacted maxillary Canines can be made with sector location than angular measurement in panoramic radiograph but CBCT is better predictor for root resorption.
