Prevalence of two-rooted permanent mandibular canines: A preliminary study

Aim: The aim of this study is to determine the prevalence of two roots of mandibular permanent canines on intraoral periapical radiographs (IOPARs). Methods: Two hundred and two IOPARs of patients in the age range 18–70 years were retrospectively analyzed for the presence of two roots in permanent mandibular canines. Statistical Analysis and Results: The data obtained were analyzed using Microsoft Excel (Version 2007) for Windows. Three patients out of 202 exhibited two roots, indicating the prevalence to be 1.48%. The mean age of the patients depicting two roots was 37 years. All the patients were females. In all the three patients, the additional root was noted on the left side canines. Conclusion: This study demonstrates the prevalence of two-rooted mandibular permanent canine.
