The importance of access cavity prepaiation in the success of endodontic treatment cannot be overemphasized. Orthograde obturation of a root canal that apparently looks calcified in the radiograph is a challenge to the operator. Proper knowledge of the tooth anatomy and very careful orientation of the bur are essential to uncover the remnant of a canal. Two case reports, where previous unsuccessful attempts to locate the root canals were made, are presented. In both the cases, the apical direction of the access cavity preparation was at fault. A carefully directed long shank round carbide bur uncovered the calcified orifices and the canals were negotiated with the use of thin root-canal instruments moistened with an E.D.T.A. preparation.
