“…Three-dimensional imaging of teeth with MB2 canals prior to endodontic treatment may help to increase the success rate of root canal therapy. While micro-CT facilitates endodontic studies in the laboratory (36), CBCT scans may be useful in clinical settings due to advantages such as lower radiation dose (37-39), higher resolution (39), and isotropic voxels (40). In a pilot study, Blattner et al (4) assessed CBCT scans’ ability to accurately confirm or disconfirm the existence of MB2 canals in maxillary first molars.…”

BackgroundThe 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.ObjectivesThe 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 MethodsThe 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 (∠MDP), and the angle formed by the mesiobuccal, distobuccal, and MB2 canal orifices (∠MDMB2) 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.ResultsOf 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 ∠MDP and ∠MDMB2 were detected and evaluated. A moderate positive correlation was found between the ∠MDP and the ∠MDMB2. To predict the ∠MDMB2 values, it was shown that the ∠MDMB2 increased by 0.420 degrees when the ∠MDP increased by 1 degree. If the ∠MDP was greater than 90.95 degrees, there was a 78% probability that MB2 canals could be found.ConclusionThe determination of the presence of MB2 in the maxillary first molars may be carried out using CBCT scans. If the ∠MDP 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 ∠MDP and the ∠MDMB2, the localization of MB2 canals may be easily performed in relation to the main MB canal.

“…The major advantages of dental CT scans over conventional medical computed tomography scans are also difficult to overlook. First, the radiation dose of dental CBCT scans is dozens of times lower (34-102 mSv) than conventional medical CT scans (200-500 mSv) (15,16). In addition, a dental CT scan has about eight times higher resolution than does a medical CT scan (7).…”
