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. Compare the Influence of immediate and delayed post space preparation on the sealing ability of AH Plus-Gutta Percha and Resilon-Epiphany system; and 2 Compare the sealing ability of Resilon -Epiphany sealer and GP-AH Plus sealer.
