Radiographic analysis of interorifice distance and canal configuration in mesial roots of mandibular first molars
Abstract
Introduction: The Middle Mesial Canal (MMC) is an additional root canal that can be present in the mandibular molars of some patients with high chances of being missed. The aim of this study is to determine the inter orifice distance between Messiobuccal (MB) and Mesiolingual (ML) canal orifice and its association with the presence or absence of MMC using CBCT to help the operator clinically in identifying the presence of MMC. Methods: 50 CBCT samples consisting of 100 permanent mandibular first molar teeth were analysed. The distance between the mesiobuccal and mesiolingual orifice was recorded. Statistical Analysis such Independent T test and Pearson correlation were used to determine the association between MB and ML interorifice distance and presence of MMC and variation in the prevalence of MMC among male and female and different age groups. Results: The mean distance between MB and ML canal orifice was 3.19 ± 0.42mm, in the presence and absence of MMC the mean distance was 3.66±0.24mm and 3.07±0.38 mm respectively. The mean inter orifice distance in males was 3.29 ± 0.38 mm and in females was 3.08 ± 0.45 mm.
