Antibacterial Effect of Bioceramic and Mineral Trioxide-Aggregate Sealer on Enterococcus-faecalis

Objectives: To analyze antibacterial effect of Bioceramic and Mineral Trioxide Aggregate sealer on E.faecalis isolate clinic at 2 minutes (freshly mixed), 4 hours (initial setting), 1 day and 7 days after mixed the sealer
Methods: Antibacterial effect of Bioceramic and Mineral Trioxide Aggegate sealer was assessed by direct test contact. Each sealer contacted with E.faecalis isolate clinic at 2 minutes, 4 hours, 1 day and 7 days after mixed the sealer. This suspension was poured in agar medium and incubated for 24 hours. The colony in agar plates counted with colony forming unit (CFU)
Results: The significant differences were shown by Bioceramic and Mineral Trioxide Aggregate sealer at 7 days, between Bioceramic at 2 minutes (freshly mixed) and 4 hours (initial setting), and also between Bioceramic at 4 hours (initial setting) and 7 days after mixed the sealer.
Conclusions: Both of Bioceramic and Mineral Trioxide Aggregate sealer have a good antibacterial effect when freshly mixed, initial setting and 1 hour after mixed the sealer, but at 7 days Mineral Trioxide Aggregate was greater. Mineral Trioxide Aggregate sealer has a constant antibacterial effect until 7 days.
