| Abstract |
| Enterococcus faecalis is the most resistant bacteria in root canals, that has esterase-like activities that enable the bacteria to hydrolyze resin-based materials. Therefore, this study was conducted to evaluate gap percentage, of two types of bioceramic and BC/resin-based sealers in comparison to resin-based sealer regarding the presence or absence of E. faecalis in the treated root canals. The aim of the present study was to determine the effect of E. faecalis on sealing ability and biodegradation of three different types of sealers;1-AH Plus (DentSply, Germany) epoxy resin-based sealer, 2-SureSeal (Sure-Endo, Korea) BC sealer, and 3-GuttaFlow Bioseal (Coltene, Whaledent) epoxy resin and bioactive material.: One hundred twenty roots were randomly divided into three groups according to the type of used sealer: Group A: Roots were obturated using AH Plus sealer, group B: Roots were obturated using S.S root and group C: Roots were obturated using GFBS. All groups were subdivided into four subgroups according to the type of inoculation: Subgroup 1 “roots inoculated with E. faecalis”, subgroup 2 “roots non-inoculated with E. faecalis”, subgroup 3 “roots inoculated with dead bacteria” and subgroup 4 “roots inoculated with media only”. By comparing the four treatment subgroups: Subgroup “with bacteria” showed the highest statistically significant gap % values in AH plus and GFBS. While in S.S it showed no statistically significant difference with subgroup “dead bacteria”. It is better to use BC sealers in cases expected to have a high percentage of E. faecalis. |
