چکیده
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 MB 2 canals of the permanent maxillary first molar of a Sulaimani population were within the normal range.
