TOMOGRAPHICAL ANALYSIS OF ROOT CANAL VARIATIONS IN PERMANENT MANDIBULAR CENTRAL INCISORS

Abstract

Objective: The objective of this study was to analyze root canal variations in permanent mandibular central incisors using cone beam computed tomography.

Design Place and Duration of Study: This descriptive study was undertaken in department of radiology, Rehman college of Dentistry, Peshawar, from 15th October 2022 till 15th April 2023.

Meth0oodology: Cone Beam Computed Tomography scans of 128 patients of both genders between 18 and 60 years of age were studied and The Cone Beam Computed Tompgraphy scans were studied for type of mandibular central incisor. Results were analyzed with the help of SPSS (version 21). Chi square test was done to stratify teeth type among genders to see effect modifiers. P-value of 0.05 was considered significant.

Results: Out of 128 CBCT scans of patients (n=128), there were 70 females (54.68 %)and 58 males (45.32%) having mean age of 28.7 years, ranging from 22-41 years with a standard deviation of 5.25 years. Most of the mandibular central incisors were type I (n=91, 71.09%) followed by Type III canals (n=37, 28.91%). Type II and type IV were not found.

Conclusion: Most of the mandibular central incisors are type I followed by type III. Type II and IV were not found in our population.
