Abstract :
OBJECTIVE: This study aims to measure the distance between the root canals and inter-radicular region of mandibular 1st and 2nd molars using dental volumetric tomography (DVT). MATERIALS AND METHOD: Mandibular DVT images of 50 first-molar teeth and 50 second-molar teeth of 80 patients were examined retrospectively. The shortest distance from the root canal wall to the inter-radicular region was measured at 2 mm below the bifurcation level at axial sections. Measurements were made by 2 radiologists, and arithmetic means were calculated for each area. The differences between the groups were analyzed with two-way ANOVA. Besides, Tukey HSD test was used for pairwise comparisons (p=0.05). RESULTS: The root canals of the 1st molar teeth were closer to the inter-radicular region than those of the 2nd molar teeth (p=0.009). When the thickness of root canal walls of different types of molars was compared pairwise, the mesiobuccal canal had the lowest measurement (p 0.05). The distance of the distal canal to the bifurcation area was higher than that of the mesiobuccal and mesiolingual canals (p=0.000). There was no statistically significant difference between the distobuccal and distolingual canals (p 0.05). CONCLUSION: The root canals of the 1st molar teeth were closer to the inter-radicular region than those of the 2nd molar teeth. Measurements of different root canals of the 1st and 2nd molar teeth revealed differences in thickness. Overall, the order was MB ML DL DB D. Accordingly, over- instrumentation should be avoided particularly in mesial canals to avoid complications such as strip perforation and vertical fracture.
