Abstract

The root canal system is complex and the canal may branch, divide and rejoin taking various pathways to the apex.One of the predominant causes of the failure of root canal treatment in mandibular premolars is due to the variations in root canal anatomy. The aim of this study was to survey the root canal morphology of mandibular first and second premolar teeth in a South Indian population using CBCT analysis.The sample included 150 CBCT images comprising mandibular first premolars and second premolars were collected from Saveetha Dental College and Hospitals.The study showed that Type 1(1-1) vertucci classification is seen in most of the mandibular first and second premolars.Within the limits of this study, Type I [1-1] Vertucci's classification is seen in most of the first premolar and second premolars.It can be concluded from the results of this study that mandibular first and second premolar teeth present a wide variety of radicular features, with one root and one canal being found in majority of cases.
