Prevalence of untreated second canal in the mesiobuccal root of maxillary molars and its association with apical periodontitis: A cone beam computed tomography study

This study aimed to evaluate the prevalence of mesiobuccal 2(MB2) canals not located/treated in maxillary molars and correlated their non-treatment with presence periradicular lesion. The was conducted on 180 cone beam computed tomography (CBCT) scans. examinations added up 210 teeth analyzed (140 first 70 second molars). non-located/treated MB2 periapical lesions mesiobucal(MB) root identified by observation axial subsequently sagittal coronal slices. Among evaluated, 91.4% (n=192) had canal, while 8.6% (n=18) did have this canal. In (n=133), lesion observed 85.0% (n=113). (n=59), 72.9% (n=43). MB related non-location/treatment canal higher when it an independent
