Personaly I make The filling of The cavity after 12 HouRSS, untill than The cavitatea îs full with provisoral material.
In terms of post space preparation, the required post space may be prepared either immediately after the completion of the endodontic procedure using hot pluggers or alternatively at a later stage after full setting of the sealer using rotary instruments [9]. Performing post space immediately after root canal obturation but before sealer cement sets may, however mean that the apical seal remains intact [10]. Yet the common procedure is late removal of the coronal part of the root canal filling at a subsequent visit [9].
If post space and post itself are prepared in the same session as the root canal fillings, these aseptic conditions may be easily followed with no additional efforts but in some cases the evaluation period is needed to analyse the restorability of the tooth with post & core [9]. Since there are different schools of thoughts regarding the critical time to carry out this procedure, this aspect is under extensive research. The dye penetration commonly used for leakage studies do not require any sophisticated materials but they give questionable result. SEM is a better means of assessing the adaptation because it has larger depth of field, higher resolution and better magnification at the interface [11].
