Investigation the angulation of maxillary impacted canines by using cone-beam computed tomography

Aim: This study aimed to evaluate the angulation and localization of unilaterally impacted canines by using CBCT. Methodology: Seventy-two images were included in the study based on the inclusion criteria. Demographic information (age and gender), localization and angulation of the impacted canine teeth were recorded. Canine angulation was measured between the two lines drawn on the coronal section of CBCT, with the first line drawn from the crista galli to the anterior nasal spine and the second line drawn along the long axes of the impacted canine teeth. Results: The mean age was 35.42±12.29 years in men and 31.10±11.09 years in women. In women, 16 of the impacted canines were on the right and 23 were on the left side, while in men, 21 of them were on the right and 12 were on the left side. Mean angulation was 34.6° (range, 17.6°-64.4°) for women and 36.2° (range, 21.4°-56.3°) for men. A weak negative correlation was found between patient age and angulation (p=0.49, rho = - 0.233). Conclusion: Angulation of maxillary impacted canines is an important predictive factor in orthodontic treatment. In the present study, no significant difference was found between angulation and canine localization and gender.   How to cite this article: Laçin N, Yalçın M.
