Endodontically treated teeth often require a post-and-core build-up for restoring the teeth to optimum health and function. The removal of gutta percha from the root canal filling, to prepare the post space is most critical in success of the endodontic and prosthodontic treatment. A 4 mm remaining length of root canal filling, after post space preparation, is commonly assumed to maintain sealing ability similar to that of the intact filling. Post space may be prepared either immediately using

The purpose of this study was to investigate the effect of immediate and delayed post space preparation on the integrity of the apical seal along with the techniques of obturation of root canal and the method of gutta percha removal for post space preparation.
