Radiographic assessment of maxillary canine impaction

Abstract

Aim-The aim of this study was to develop and validate a large-scale prediction model for impaction of maxillary canine based on linear and angular radiographic measurements. Methodology- From the available database all patients with at least two panoramic radiographs recorded between the ages of 7 and 14 years with an interval of 1 to 3 years (T1 and T2) were selected. At T1, linear and angular readings were done. At T1, 572 patients with unilaterally or bilaterally impacted canine were chosen from 2361 records. Thirty-six patients remained untreated at T2 and were used as research participants. Logistic regression analysis was used to construct the prediction model.
