Background And PurposeAim is to evaluate the antibacterial activity and physical properties of Biodentine containing chlorhexidine (CHX)/cetrimide (CT) mixtures at 24 h.Materials And MethodsPowder formulations of CHX (2.5%) and CT (2.5%) were added to the powder of Biodentine and served as experimental groups (EXP). Antibacterial free groups were designed as control (CNT). The antibacterial acitivity (AB) (n = 5; for each) of disc-shaped specimens against Streptococcus mutans and Lactobacillius casei and compressive strength (CS) (n = 10; for each) tests used both for groups after 24 h after polymerization.Statistical Analysis UsedNormality of data were tested with the Shapiro-Wilk test. Significant differences were analyzed with the Mann-Whintey U test for both the methods (agar disk diffusion and compressive strength) at a significance level of P < 0.05.ResultsSignificantly higher antibacterial effects were obtained in EXP groups compared to the CNTs for both bacteria after 24 h, distinctly (P < 0.01). No differences were found between groups regarding the CS values (P > 0.05).ConclusionSince the incorporation of 5% CHX/CT to the Biodentine exhibited acceptable antibacterial activity without hampering compressive strength values at 24 h, this combination could be a promising alternative for eliminating the residual bacteria for indirect pulp-capping therapies.
