摘要

Objectives

The present study aims to examine and classify the localization of canine teeth impacted in the maxilla for various reasons, their relationship with adjacent structures, and the developing pathologies by using cone beam computed tomography (CBCT).

Material and method

CBCT images taken for various reasons from 175 patients with maxillary impacted canine teeth that met the research criteria were examined. Demographic characteristics of the patients such as age and gender were recorded. The maxillary impacted canine teeth were examined by using CBCT in terms of their locations, relationship with the maxillary sinus, nasal floor and nasopalatine canal (NPC), relationship with adjacent teeth and the associated pathologies.

Results

A total of 209 maxillary impacted canine teeth of 175 patients were examined. Of the patients included in the study, 37.3% were male, while 62.7% were female. The mean age was found as 35 (age range 18–70). The rate of unilateral impacted canine teeth was 67.5% and 52.6% of the canine teeth were found to be located on the right side of the maxilla. Canine teeth were palatally impacted in 79% and 89% were found to be in a mesioangular position. The rate of canine teeth associated with the nasal cavity floor was found to be 7%, the rate of canine teeth with roots extending into the maxillary sinus was 6%, and the rate of canine teeth associated with NPC was found to be 15%. When the relationship of maxillary impacted canine teeth with the surrounding anatomical structures was examined, maxillary impacted canine teeth of male were found to have a higher relationship with the nasal cavity floor. The rate of pathologies associated with maxillary impacted canine teeth was found to be 22.5%. The most common pathologies were intracoronal resorption in maxillary canine teeth (8%) and root resorption in lateral incisors (7%).

Conclusion

The results of the present study show that maxillary impacted canine teeth can remain for many years without causing pathology. However, it is crucial to evaluate them comprehensively by using CBCT when orthodontic or surgical intervention is planned.
