Three-dimensional evaluation of mandibular canine impaction characteristics and their relationship with lower incisor root morphometry

2022

To three-dimensionally evaluate the characteristics of mandibular canine impaction with the morphometry of the roots of the lower incisors.Cone-beam computed tomography (CBCT) scans of 35 individuals (18 males and 17 females) with a mean age of 14.37± 10.26 years were evaluated. Forty-three impacted mandibular canines (IMbC) were evaluated. Their location, sector and level of impaction were determined. Likewise, the distances of the canines to the occlusal plane, the angulations with respect to the midline and adjacent lateral incisors, the length of the impacted canines, and of the lower incisors were measured. Finally, the presence of incisor root resorption was determined. Chi-square and…
