Influence of Immediate & Delayed post space preparation

The success of endodontic therapy depends on the ability to establish and maintain a apical seal. One of the major factors of root canal failures is coronal leakage caused by recurrent caries open crown margins leakage through temporary restorations or failure to have a provisional placed on a treated tooth in timely manner. Therefore placement of a post in canal often becomes necessary to retain the core wherever indicated.Hence the aim of the study was to; 1.To compare the Influence of immediate and delayed post space preparation on the sealing ability of AH Plus-Gutta Percha and Resilon-Epiphany system 2.To compare the sealing ability of Resilon -Epiphany sealer and GP-AH Plus sealer
