Abstract
Objective: To find the incidence of two canals, and root canal morphology of mandibular incisors in Pakistani population thus preventing missed canals during endodontic procedures. Materials and Methods: 100 CBCT scans taken in Armed Forces Institute of Dentistry, Rawalpindi, Pakistan were studied to determine the presence of second canal as well as determining the root canal morphology according to Vertucci’s classification, in mandibular incisors. The data was analyzed using SPSS 20.0. Results: Images of 400 mandibular incisors were observed. 73.8% of the incisors had one canal (Vertucci’s Type I) and 26.2% had two canals (Vertucci’s Type II 4%, Type III 20.4% and Type IV 1.7%). Conclusion: Overall, 26.2% incisors had two canals, so the dentists performing root canal treatment of mandibular incisors must be aware of this fact to avoid missed canal. CBCT can be used successfully to determine root canal configurations.
