Comparative Analysis of Morphological Characteristics and Localization of Maxillary Impacted Canines using Cone Beam Computed Tomography.

BACKGROUND This study aimed to evaluate the crown length and width and root length and dilacerations in unilateral impacted maxillary canines, compared with contralateral erupted canines, and to investigate the relationship between the morphology of impacted canines and their localization. MATERIAL AND METHODS Pretreatment cone beam computed tomography (CBCT) of 40 patients (age range 11-34 years) with unilateral impacted maxillary canines (IC) were analyzed. The crown length, crown width, root length, and dilacerations of IC were assessed and compared with that of contralateral erupted canines (CC). The eruption path length, impaction depth, and impaction height were measured, and mesio-distal and labio-palatal positions of the IC were determined. RESULTS Crown length and width of IC were significantly greater, by 0.15 mm and 0.26 mm, respectively, than that of CC (P.
