The assessment of impacted maxillary canine position with panoramic radiography and cone beam CT

Abstract

Objective: The aim of this study was to correlate the position of impacted maxillary canines on panoramic radiography with cone beam CT (CBCT) and analyse the labiopalatal position of canines and root resorption of permanent incisors in CBCT according to the mesiodistal position of canines on panoramic radiographs. Methods: This study was a retrospective radiographic review of 63 patients with 73 impacted maxillary canines. The mesiodistal position of the canine cusp tip was classified by sector location and analysed on 73 impacted canines from 63 panoramic radiographs. The labiopalatal position of the impacted canines and root resorption of permanent incisors were evaluated with CBCT. The sector location on panoramic radiographs was compared with the labiopalatal position of impacted maxillary canines on CBCT. The statistical correlation between panoramic and CBCT findings was examined using the x 2 test and the Fisher's exact test. Results: Labially impacted canines in CBCT were more frequent in Panoramic Sectors 1, 2 and 3, mid-alveolus impacted canines were more frequent in Sector 4 and palatally impacted canines were more frequent in Sector 5. There was a statistically significant association between the panoramic sectors of the impacted canines and the labiopalatal position of the canines (p , 0.001). Root resorption of permanent incisors showed a significant difference according to sector location (p , 0.001) and was observed in Sectors 3, 4 and 5. Conclusions: This study suggests that the labiopalatal position of impacted canines and resorption of permanent incisors might be predicted using sector location on panoramic radiography.

Radiographic Analysis and Prevalence of Impacted Maxillary Canine Teeth in Children Between 8 and 16 Years

“…When analyzing horizontal location of the impacted canines of our population the highest percentage stood at sectors l, ll and lll being similar that found by Jung et al (2012) in children under 15 years (Warford et al, 2003;Lindauer et al).…”

Diagnostic Value of Panoramic Radiography in Determining the Position of Impacted Permanent Maxillary Canines

“…Disturbed development of permanent maxillary canines is common due to having the longest development period, the most superior position of development and the most difficult developmental path (6)(7)(8)(9).…”

“…Impacted canines may lead to such problems as displacement and resorption of adjacent teeth, cystic degeneration, canine ankylosis, and a small dental arch (9). Therefore, the treatment method of choice is surgical exposure and placement of the tooth in the dental arch.…”

Comparison of panoramic radiography and cone-beam computed tomography for qualitative and quantitative measurements regarding localization of permanent impacted maxillary canines

“…Criteria used in various previous studies were modified to assess DPR and CBCT images of IPMCs. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] The amount of magnification, which was determined by the manufacturer (×1.3), was taken into account in the measurements of DPR images. Morphology of the adjacent PLI, contact relationship between the IPMC and the adjacent PLI, presence of root resorption in the adjacent PLI, and angle measurements were evaluated in DPR images and in the coronal and sagittal sections of CBCT images ( Table 1).…”
