Abstract The effects of three apical preparation sizes and three sealer materials on fracture resistance and sealing ability of endodontically treated roots were investigated in this study.Two hundred and twenty intact extracted maxillary human anterior teeth were used. The crowns of all teeth were removed at the cementoenamel junction, and the pulp tissues were removed from all roots. The roots were randomly divided into two main categories for both parts of this study. |
