Abstract

Aim: The aim of this study was to survey the root canal morphology of mandibular incisor teeth in a Palestinian population using radiographic approach. Materials and Methods: Five hundred and twenty two extracted mandibular incisor teeth were randomly collected from Palestinian population. The teeth were radiographed from a mesiodistal direction and examined for the presence of a second canal and for the type of canal configuration. Results: All teeth had single root. Three hundred and sixty nine teeth (70.7%) had one canal (type I Vertucci classification). The rest (29.3%) had a second canal (type II and III). Conclusion: Mandibular central and lateral teeth were mostly found to have one root and Type I canal system.
