Abstract :
Aim: The objective of this study was to evaluate the mesial developmental groove depth and to correlate it with the root canal anatomy in maxillary premolars using CBCT. Methods: Hundred extracted maxillary premolars were included in the study. Samples were stored in saline with 0.2% thymol until use. Each sample was examined for number of canals, canal configuration, maximum depth of mesial developmental groove with its position coronal to apex and minimum dentin thickness at the position of maximum mesial developmental groove depth using CBCT. Statistical Analysis: One–way ANOVA–F and Pearson’s correlation tests were performed for analysis. Results: Majority of the maxillary premolars exhibited two canals. The incidence of type IV canal configuration (most prevalent) for the maxillary first and second premolars were 57.6% and 41.6% respectively. The mean maximum groove depth was found to be 0.86 (±0.42) mm and was located at a mean distance of 7.13 (±2.17) mm coronal to the apex. The mean value for minimum dentin thickness at the position of maximum groove depth was 1.05 (±0.23) mm. Conclusion: The depth of mesial developmental groove, the minimum dentin thickness and the position of maximum depth of groove varied with the number of canals and canal configuration
