A Clinical Study on the Prevalence of Additional Canals -MB2 and MB3in Mesiobuccal Root in Maxillary Molars

The goal of successful endodontics is the total preparation of the whole endodontic space. The success of endodontic therapy is dependent on the quality of cleaning of the entire root canal system. Varying morphology in human teeth is a common occurrence. Therefore, it is of importance to have a thorough knowledge of the dental anatomy and its variation prior to initiation of treatment. It is known that failure to find and treat these additional canals may modify the long-term prognosis of treatment. The maxillary permanent molars have been studied by many authors but the results are disparity, both as regards the number of canals found in the mesiobuccal (MB) root and in their disposition.
