Abstract

Objective: To determine the antibacterial effect of silver diamine fluoride and glass ionomer cement restoration against streptococcus mutans. Materials and methods: This study included 10 blood agar plates, the anti-bacterial efficacy of each matter was estimated against streptococcus mutans using agar diffusion test. Streptococcus mutans was prepared on blood gar plate. Three wells (A,B,C) with a diameter of 5 mm were performed in each plate and totally filled with one of the tested substances. The test materials were divided into three groups: group A (SDF): silver diamine fluoride, group B (GI): glass ionomer and group C (SDF+GI) were placed into uniform wells that punched in the agar plate. The plates were left for 30 minutes for diffusion at room temperature, then incubated for 48 hours at 37 °C in the incubator. A digital caliper estimated the aacterial growth zones in millimeter. Results: Results of the current study showed significant antibacterial effect of SDF against streptococcus mutans compared with SDF and GI combination and showed that GI has no significant antibacterial effect against streptococcus mutans. Conclusions: SDF has excellent bacteriostatic activity against cariogenic strains of S. mutans, GI has no significant antibacterial effect against s. mutans and SDF and GI combination has lower antibacterial effect compared with SDF alone.
