Abstract

Background and aim: Determining the accuracy of panoramic radiography in assessing the labio-palatal position of maxillary impacted canines and root resorption of the adjacent tooth.
Materials and methods: We used these further variables: angulation, mesiodistal position, and vertical position, which respectively were based on the angulation of canine about the midsagittal plane, five sectors on panoramic radiographs using the Allcandri method, and division of incisor adjacent to the impacted canine into three sectors. labio-palatal position of the MICs and root resorption of permanent incisors were evaluated on CBCT. The statistical correlation between the investigated variables on panoramic and position of MICs and the root resorption of the adjacent tooth on CBCT were examined using independent t-test, Mann-Whitney test, and Fisher's exact test.
Results: In respect of the mesiodistal position of the cusp tip of the MIC, the labially localized MICs were common in sectors 1 and 2, and the palatally localized MICs were more frequent in sectors 3, 4, and 5. Concerning the vertical position of the MIC's cusp tip, the localized labial MICs were more common in sectors 1 and 3, and palatally localized MICs were more frequent in sector 2. The mean angle of MICs about the sagittal plane was significantly higher in the palatally localized MICs. There was no significant correlation between the MIC's tip, mesiodistal position, and the adjacent tooth's root resorption.
Conclusion: Results showed the correlation coefficients among the upper pharyngeal airway width, and ANB and Witt's analyses were not significant. These results can reinforce the probability of class III malocclusion inheritance.
