The In Vitro Antimicrobial Efficacy of Two Different Bioceramic Sealers against Enterococcus Faecalis

Abstract Background: The purpose of this study was to evaluate the antimicrobial effect of two bioceramic sealers (Ceraseal-B and Bio-C) against Enterococcus faecalis. Methods: The antimicrobial effect of the two bioceramic sealers were assessed by the agar diffusion test (ADT) method using AH Plus sealer as a control. The results were reported in terms of the diameter of the growth inhibition zones in mm. The zone of inhibition for each sealer was measured at 24h, 48h and 72 hrs. Results: The results showed that amongst the bioceramic sealers tested, Bio-C had a greater zone of inhibition compared to Ceraseal-B. This showed that Bio-C had a greater antimicrobial activity compared to Ceraseal-B. However, both of the freshly mixed bioceramic sealers had a lesser antimicrobial activity against the control group (AH Plus). Conclusion: The invitro antimicrobial efficacy of Bio-C sealer was greater than that of Ceraseal-B sealer.
