Prevalence of Untreated Mesio-Buccal 2 Canal in Maxillary First Molars Reported in KSA Since 2010: A Systematic Review

Several aspects are involved in the success of an endodontic therapy. Because root canal treatment is so complicated, it can't be evaluated using two-dimensional radiographs. Endodontic failure can occur if any section of the canal is overlooked and left untreated. The root canals of the first and second molars are the most complicated of all the maxillary teeth. Locating the mesio buccal (mb2) canal in the maxillary teeth for endodontic treatment is difficult. The mb2 canals are located utilizing three-dimensional technology and cone beam computed tomography (CBCT). The primary goal of this research is to conduct a systematic evaluation of publications that have reported on the occurrence of mb2 canal in maxillary first molars. Many studies in Saudi Arabia have found that the incidence of mb2 in maxillary first molars ranges from 23.3 percent to 70.6 percent, and that the incidence in maxillary second molars is about 19.8%. A few studies also found that direct viewing of the root, followed by troughing, was used to find an mb2 canal that was not visible on a CBCT scan.
