Aim & Objective: The aim of the present study was to evaluate the root canal morphology of the mesial root of two rooted mandibular second molars in Meerut district (U.P.), population and predict the co-relation between the inter-orifice distance and the canal configuration.
Method: Randomized data of patients who were advised CBCT for a purpose other than this study was collected from the Department of Oral Medicine & Radiology. A total of 174 scans were observed, in which the mesial root of 207 mandibular second molars were evaluated for the study. The samples were viewed in axial, sagittal as well as coronal planes to determine the root canal configuration and measure the inter-orifice distance between the mesio-buccal and the mesio-lingual canal for all the samples.
Result: The most common canal configuration observed was Vertucci's Type IV followed by Vertucci's Type II. Type II canals had a smaller mean inter-orifice distance (2.14mm ) There was a significant correlation between the inter-orifice distance and root canal configuration in all the observed samples.
Conclusion: Vertucci’s Type IV is the most common canal morphology found in the mesial root of mandibular second molar and the inter-orifice distance can be used as a reliable predictor of canal morphology. Canals with smaller inter-orifice distance had a tendency for Type II configuration.
