Abstract
The aim of this study was to evaluate the effect of different angulations
of impacted maxillary canine on root resorption of adjacent teeth using
cone-beam computed tomography. Thirty CBCT scans of patients who had
a unilateral or bilateral impacted maxillary canine were included.
1) from CBCT axial view, the position of the maxillary impacted
canine investigated either labial, palatal position or mid alveolus
2) from panoramic view, canine angulation to the occlusal plane and
lateral incisor was measured.
3) Proximity to and/or direct contact of the impacted canine with
incisors or premolars (yes/no).
4) location and severity of root resorption was determined vertically as
apical, middle coronal and horizontally as palatal, buccal, mesial, or
distal
5) severity of resorption was graded as: no resorption,slight resorption,
moderate resorption and severe resorption.
