Abstract

Aim: To determine the prevalence of root fenestration (RF) in an Iranian subpopulation using CBCT. Methods: This cross-sectional study was carried out in Kermanshah, Iran on all patients requiring CBCT scan for various indications. RF was categorized into 6 types. Also, periapical status was classified in 3 levels. Data was analyzed using descriptive statistics, multiple logistic regression, and chi-square test (α=0.05). Results: In this study 230 CBCT images with a total of 3101 teeth were evaluated. RF was observed in 36.9% of the images and 3.9% of the teeth. RF was more common in maxilla and on the buccal side. Also it was more frequently observed in canines (25.8%). The most common type of RF was type I i.e. exposure of the apical third of the root regardless of involvement of the anatomic apex. Moreover, the most frequent involvement of periapical tissues was level 1 i.e. widened periodontal space without radiolucent periapical lesion. Conclusion: The overall prevalence of RF was 3.9%. RF was more common in maxilla and on the buccal aspect. The most common teeth involved with RF were canines followed by lateral incisors. RF type I was more frequently observed. Moreover, RF was more commonly associated to level 1 of periapical involvement. © 2020 Lahore Medical And Dental College. All rights reserved.
