PREVALENCE AND PATTERNS OF MANDIBULAR IMPACTED CANINES. A CBCT BASED RETROSPECTIVE STUDY
Demographic studies are important for understanding the prevalence and various patterns associated with impacted canine for early diagnosis and success of treatment. The aim of this study was to evaluate prevalence and different patterns of mandibular impacted canines (MIC), using cone beam computed tomography (CBCT).
CBCT records of 3469 patients were taken from two different radiological centers. Sorting of data for MIC was done using Romexis viewer 4.6.0. R. Data was analyzed statistically and descriptive statics for age, gender, side and position of impaction were generated. Chi-square test was used to evaluate gender dysmorphism in terms of presence, position and side of MIC. A p-value of <0.05 was taken as significant.
20 patients with MIC were identified with a mean age of 19+2.2 years. 85% of MIC were unilateral while 15% were bilateral. 15 % of MIC were transmigrated and were unilateral with a male to female ratio of 2:1.70% of MIC were labially placed. Bilateral impactions were found only in males. No gender dysmorphism was noted for presence, position and side of impaction (p value >0.05).
The prevalence of impacted mandibular canine was 0.57% while prevalence of transmigration was 0.09%. Unilateral and labial position of impacted canine was more predominant.
