Background: A successful endodontic treatment depends upon complete debridement of the root canal system. Therefore, the dentist should have thorough knowledge of the root canal morphology of the teeth. Thus, the aim of this study is to evaluate the presence of the second canal in extracted mandibular incisor teeth. Materials and methods: For this study we collected 50 freshly extracted mandibular incisors. In which 27 were central incisors and 23 were lateral incisors..  All teeth were placed in 5.25% sodium hypochlorite for 30 minutes and after that access cavities were prepared  and pulp tissue was dissolved by immersing the teeth in 5.25% sodium hypochlorite for 24 hours. India ink was injected into the pulp chamber with an endodontic irrigating syringe with gauge 27 needle. The stained teeth were air dried and decalcified with 5% nitric acid  for 3 days. The specimens were then dehydrated in ascending concentrations of ethyl alcohol (70%, 96% and 99%) for 12 hours each. Finally, transparent specimens were obtained by immersing the dehydrated teeth in methyl salicylate solution into which teeth were stored until examined. The specimens were examined using magnifying glass. The canal configurations were categorized into the first four types of Vertucci’s classification. Results: The result of our study shows that type I is most prevalent canal configuration in both mandibular central (66.66%) and lateral incisors (65.21%). In mandibular central incisors the prevalence of canal configuration follows as: type III followed by type IV and type II. In mandibular lateral incisors the prevalence of canal configuration follows as: type III followed by type II and type IV. Conclusion: Our study concluded that type I is most prevalent canal configuration in both mandibular central and lateral incisors. A thorough knowledge of tooth morphology, canal configuration are important factors for a successful treatment.
Key words: Mandibular incisors, Vertucci’s classification.
