Abstract

Objectives

In this retrospective study, the frequency and severity of ectopic eruption in the children's permanent canines, changes between the impacted canine parameters on orthopantomography (OPG) taken for routine follow-up were demonstrated. Also, it was aimed to reveal the differences between OPG and cone beam computed tomography (CBCT).

Methods

Ten thousand (5020 girls, 4980 boys) pediatric patient, were retrospectively investigated for the presence of impacted canine radiographically. OPG and CBCT images of 343 pediatric patients (207 girls, 136 boys) detected impacted canines (n = 432) were evaluated in four steps that the angular and linear measurement, position and status relationships with adjacent anatomical structures were investigated.

Results

The incidence of impacted canine in children was 3.43% (4.02% girls, 2.73% boys). The percentage of adjacent lateral incisor' resorption was 33%. Although the presence of resorption in lateral incisors in contact with a canine was found to be statistically significant (p = 0.02), there was no statistically significant relationship the follicle size and localization of canine in the transverse plane. When images were compared, it was found that there was a statistically significant difference between CBCT and OPG about the parameter of canine angulation to the midline and parameter of canine angulation to the lateral incisor.

Conclusions

Pediatric dentists should prefer OPG as the first choice for radiographic imaging for the diagnosis of impacted canine at an early age. Follow-up OPGs should be carefully studied with advancing age. The CBCT should be preferred to prevent complications, to view its relationship with adjacent anatomical structures and canine localization in detail.
