Abstract

The purpose of this study was to compare the root canal filling remnant and patency between Bioceramic sealer group and Epoxy-resin sealer group after removing by using Ni-Ti rotary with eucalyptus oil and GuttaClear®. Eighty human extracted lower premolar teeth with 1 root canal, 1 apical foramen and patency. The teeth were simple randomly divided into 2 experimental groups (n=40): Group 1 obturation by Gutta-percha with Bioceramic sealer [iRoot®SP] using single cone technique, Group 2 obturation by Gutta-percha with Epoxy-resin sealer [AH-Plus®] using Hybrid warm vertical compaction technique. Then each group was simple randomly divided into 2 subgroups (n=20) in removing step by Ni-Ti rotary with eucalyptus oil or GuttaClear®. Patency was checked again.  Roots were split in bucco-lingual dimension. Evaluated the remnant under Scanning Electron microscope at 1000x magnifications. The result revealed that root canal filling remnant remain in all experimental groups. Median percentage of root canal filling remnant after removing in group which obturated by Gutta-percha with Bioceramic sealer was more than in group which obturated by Gutta-percha with Epoxy-resin sealer, and mean percentage of root canal filling remnant in group which removing by using GuttaClear® was more than group which removing by using eucalyptus oil with no statistically significant difference (P>0.05). Ratio of patency after removing in group which obturated by Gutta-percha with Bioceramic sealer was less than group which obturated by Gutta-percha with Epoxy-resin sealer and in group which removing by using GuttaClear® was more than group which removing by using eucalyptus with no statistically significant difference (P>0.05). In conclusion, filling root canal with Gutta-Percha and Bioceramic sealer is retreatable and GuttaClear® is an option of solvent for removing root canal filling materials in endodontic retreatment.
