Abstract

Aim: The aim of the study was to evaluate the position and the relation of impacted maxillary canines using panoramic radiograph and CBCT, along with the evaluation of root resorption of the permanent incisors and involvement of the maxillary sinus proximity.
Materials and Methods: A total of 25 patients with 34 impacted maxillary canine, age group ranging from 13 to 32 years of both genders were included in the study. Digital panoramic radiograph and CBCT was taken for all the patients and the impacted maxillary canine were evaluated for type, position, root resorption and maxillary sinus involvement. Statistical analysis using Chi-square test and Fisher’s exact test was performed.
Results: Most of the impacted maxillary canine (IMC) position in panoramic radiograph were located at sector 5 followed by sector 1, sector 4, sector 3 and sector 2. The common labiopalatal positions of impacted maxillary canine in CBCT was palatal followed by labial and mid alveolus. Correlation between sector location on panoramic radiograph and labiopalatal position in CBCT were done and the result were statistically significant (P value = 0.002). Measurement of agreement shows high values for type of impaction in both radiographic techniques. Root resorption and Maxillary sinus involvement were statistically significant in panoramic radiograph than CBCT.
Conclusion: In the present study, CBCT imaging was significantly better than that of panoramic radiograph for determining position of impacted canines according to sector location & labiopalatal position, type of impaction, root resorption and maxillary sinus involvement. However, further studies should be carried out in future with large sample size to determine the accuracy of localization of impacted maxillary canine.
