Finding two mesiobuccal root canals named MB1and MB2 in maxillary first molar is not uncommon. Mesio-buccal-2 (MB2) canal orifice located palatally to the mesio buccall orifice and buccally as well as mesially to palatal orifices. A complete understanding of MB2 root canal morphology can contribute to the successful outcome of root canal treatment. This study conducted on CBCT scans with age ranged from 15 to 60 years which was further divide into group I (15-30 years), group II (30-45 years) and group III (45-60 years).Unilateral as well as bilateral prevalence of MB2 canal in maxillary first molar in both the genders and prevalence of MB2 canal in maxillary first molar in accordance with age were determined. Results showed overall prevalence of MB2 canal in maxillary first molar was 60.7%. In age wise distribution, group II showed greater prevalence than group I and group III showed least prevalence than others. The results were statistically significant between age groups. There was no statistical significance obtained between gender and quadrant wise. Conventional diagnostic aids such as radiographs play an important role in assessment of complex root canal morphologies. These modalities, however, do not provide detailed information of the complexity as a result of their inherent limitations. Shifting from 2D radiographic techniques to 3D radiographic techniques provides better visualization and location of these small and difficult structures.
