Knowledge of canal anatomy is essential. Failure to find a canal influences the prognosis of endodontic treatment. The aim of this study is to investigate the prevalence of Mesiobuccal canal number two (MB2 canal) in the extracted permanent maxillary first molars of a Sulaimani population. An ex vivo study on 180 extracted permanent maxillary first molars was conducted and the floor of the pulp was clearly exposed. The canal orifice was examined clinically by the aid of a chelating agent and magnifying lens. Patency of each canal was established by a no.10 k-type file. The results showed that 23.3% of the examined teeth had two canals in the mesial root (17.0% with one apical foramen and 6.3% with two separate foramens). The occurrence of MB2 canals of the permanent maxillary first molar of a Sulaimani population were within the normal range.
Key words: Prevalence, MB2 canal, maxillary first molar, Sulaimani population.
