Aim: Third molar teeth were prophylactically extracted to compensate for the evolutionary reduction in jaw size. However, due to advances in therapeutic options and recent investigative methods, patients are being given an option for varying treatment of the teeth as indicated. They commonly present a wide variety of anatomical variations including multiple canals, isthmi and apical deltas and hence the need to know their varied root canal morphology.

Materials and Methods: In this study, 238 mandibular third molar teeth were investigated by Cone Beam Computed Tomography especially for the presence of C-shaped canals and their configurations analysed.

Results: The population group examined showed a high percentage of C-shaped canals. The presence of these canals was higher in females. A buccal groove was seen in 04 (21.1%), lingual groove in 06 (31.6%) and both the grooves in 09 (47.4%). At the coronal level, 47.4% of cases showed a C4 configuration. The middle third mostly exhibited a C3 (d) configuration with a prevalence of 31.6%. At the apical third, C3 (d) canal morphology was seen in 42.1% of teeth.

Conclusion: A high percentage of C-shaped canals was observed in the population group which warrants advanced diagnostic aids and treatment protocols if these teeth have to be preserved in the oral cavity.
