Abstract

This micro-CT study evaluated the root canals of 135 mandibular incisors in a Malaysian subpopulation using Vertucci (1984) and Ahmed et al. (2017), whilst the accessory canals were classified using the Ahmed et al. (2018) system. The Fisher Exact test was used for analysis (p = 0.05). Results showed that 53% of the teeth had Type I/1MI1 canals, whilst Type III/1MI1-2-1 canals occurred significantly less often in 15% of teeth (p
