Root canal morphology of permanent incisors and canines in a Sri Lankan population

Results: Maxillary central and lateral incisors and canines typically presented with a single canal of type I canal configuration. In mandibular teeth, most of the central incisors showed type I (57.4%) canal configuration. Type III was found in 37.0% of the cases. The incidence of type III canal configuration in mandibular lateral incisors was 55.9%. The remainder was distributed mainly between type I and II. In addition, mandibular canine teeth typically presented with a single canal. Conclusions: The root canal morphology in mandibular incisors and canines is variable in different population groups. Mandibular incisor and canine root canal morphology of Sri Lankan people have closer affinities with those of people of European than East Asian origin.
