The position of the root canal filling materials at the root apex was studied using intact mandibular teeth of a cadaver. Teeth were divided into two groups. Each group received routine root canal therapy. The root canal filling materials were placed at the radiographic apex in one group, and at 0.5 to 2 mm short of radiographic apex in the other group. The position of the gutta percha at the root apex was checked radiographically and microscopically. Results showed an extrusion of the filling material out of the canal when placed at the radiographic apex. Placing the filling materials 1.0 to 1.5 mm short of radiographic apex showed an acceptable position microscopically.
