Abstract

The aim of this study was to compare the 3 panoramic interpretation methods in predicting the position of a displaced
maxillary canine and to determine the new appropriate cut-off point for buccal and palatal canine impaction. We performed a
retrospective study of 37 patients with 47 maxillary impacted canines. Patients underwent both panoramic radiograph and cone
beam computed tomography (CBCT). Panoramic radiograph methods—including magnification method or canine incisor index (CII),
angulation and sector methods—were evaluated using CBCT as the gold standard. The McNemarχ2 and Stuart-Maxwell tests were
calculated to compare the panoramic methods and CBCT. Diagnostic testing (i.e., sensitivity, specificity, accuracy) and Receiver
Operating Characteristic curve (ROC) were evaluated for new appropriate cut-off points (significance level 0.05). Of the 37 patients,
23 were female. Age ranged between 12 and 41 years (mean, 20.27±8.03). The 47 impacted canines included 11 (23.40%)
buccal, 20 (42.55%) palatal canine and 16 (34.05%) mid alveolus. The sensitivity of the 3 methods for buccal and palatal canine
impaction were between 37.5-77.42 %. There were no statistically significant difference among the magnification and angulation
method and CBCT (p = 0.80 and 0.07, respectively). However, there was a significant difference between the sector and the CBCT
(p = 0.04). In conclusion, magnification and angulation methods were interchangeable and not different from CBCT in determining
the position of impacted maxillary canines.
