Nouveaux paradigmes liés à l'utilisation des ciments endocanalaires biocéramiques : étude in vitro

Abstract : According to their interesting properties (biocompatibility, adhesion to the dentin, dimensional stability, antimicrobial properties), bioceramics root canal sealers leads to a paradigm shift. Instead of a warm vertical compaction a single cone technique may be used. We have carried out an in vitro study about the influence of two bioceramics sealers (Total Fill BC Sealer® and Bioroot RCS®) and the master cone fitting on the endodontic filling with open apexes. With the manufacturers recommendations those two sealers and a single cone technique produced a void free obturation. Using a modified single cone technique where the MC is fitted at 2mm of the WL resulted in the formation of an apical plug. Because Total Fill BC Sealer® is injected with a syringe, the fillings showed fewer voids than Bioroot RCS® but a higher risk of over filling. Considering the biocompatibility of bioceramics this filling technique could be useful when there are high risks of gutta percha overfill. Nevertheless, longer in vivo studies are required.
