Abstract
Root canal treatment through cleaning, shaping and apical sealing are crucial for periapical healing. Moreover, Coronal restoration of the root canal treated tooth is required to prevent coronal leakage and to provide function and aesthetic. The quality and timing of the final restoration has its effect on the survival and success rate of endodontically treated tooth. It has been found that full coverage restorations show a higher long-term survival rate than direct restorations. Direct restoration has an excellent short-term survival rate comparing to crowns or onlays. Long term survival is the main criteria of successful endodontic treatment. Full coverage restorations show a higher survival rate than direct restorations. The definitive restoration should be placed as soon as RCT completed. It has been shown that time of crown placement after endodontic treatment affect the survival rate of endodontically treated teeth. Finally, no need for a post if the remaining tooth structure can withstand the core material.
