Abstract

Background: The localization of the additional canal orifice is one of the primary factors influencing the success of endodontic treatment. To deal with this problem, several techniques that each have their own advantages and disadvantages have been discussed in the literature.Objectives: The aim of the present in vitro study was to review a new approach to localizing second mesiobuccal (MB2) canals in maxillary first molars using CONE BEAM COMPUTED TOMOGRAPHY (CBCT).Patients and Methods: The CBCT scans of 296 patients who were referred to the department of dentomaxillofacial radiology were included in the study. The presence of MB2 canals, the angle formed by the mesiobuccal, distobuccal, and palatal root canal orifices (ÐMDP), and the angle formed by the mesiobuccal, distobuccal, and MB2 canal orifices (ÐMDMB2) were evaluated on the axial section.Pearson correlation and multiple linear regression methods were used for all predictions. All of the analyses were performed using SPSS for windows version 22.0. A two-sided P value<0.05 was defined as statistically significant.Results: Of the 468 first molars, MB2 canals were observed in 296 subjects (141 females and 155 males). There were no statistically significant differences between females and males (P=0.300). The ÐMDP and ÐMDMB2 were detected and evaluated. A moderate positive correlation was found between the ÐMDPand the ÐMDMB2. To predict the ÐMDMB2values, it was shown that the ÐMDMB2 increased by 0.420 degrees when the6 MDP increased by 1 degree. If the ÐMDP was greater than 90.95 degrees, there was a 78% probability that MB2 canals could be found.Conclusion: The determination of the presence of MB2 in the maxillary first molars may be carried out using CBCT scans. If the ÐMDP was 91 degrees or greater, there was considered to be a higher probability that MB2 canals would be found in the endodontic cavity. Due to the positive correlation between the ÐMDP and the ÐMDMB2, the localization of MB2 canals may be easily performed in relation to the main MB canal.
