Clinical Approaching Of The Maxillary First Molar Root Canal

This paper reports the case of a maxillary first molar that presented two root canals in the Mesiobuccal root. Root canal therapy and case management are described. Features like wide crown access, adequate illumination and use of exploring files where important for successful completion of the endodontic treatment. The variations in dental anatomy play an important role in root canal therapy. A great predominance of two very close canals in the mesiobuccal root of maxillary molars has been demonstrated. Despite the current high success rate achieved in endodontic treatments, the mesiobuccal roots is still associated to a considerable number of failures due to the difficulty in locating and filling the second mesiobuccal canals. On account of this root canal therapy of these teeth should be carried out using angulated x-rays;efficient explorers;wider crown accesses;adequate lighting and whenever possible image magnification.
