Abstract

Background: Streptococcus mutans is a Gram-positive bacteria that can convert fructose and lactic acid causing a decrease in pH. The acidic atmosphere that occurs due to a reduction in the mouth's pH can accelerate the growth of bacteria thereby increasing plaque formation in teeth. Chlorine dioxide is a chemical compound that can control plaque because it can raise the mouth's pH to inhibit the growth of bacteria in an acidic atmosphere of the mouth. Chlorine dioxide with a concentration of 0.3% is the highest concentration and is safe as a mouthwash. Objective: This study aims to determine the antibacterial effect of chlorine dioxide at a concentration of 0.3% in inhibiting the growth of Streptococcus mutans. Method: This research is an in vitro experimental laboratory study. The test group used chlorine dioxide with a concentration of 0.3%, a mouthwash containing fenol as a positive control and an aquades as a negative control. The disc diffusion method is carried out to determine the value of the inhibitory zone of chlorine dioxide against bacteria. The results of the inhibition zone measurement were statistically analyzed using the ANOVA one-way test and the Post Hoc LSD test. Results: The study showed that chlorine dioxide at 0,3% had a larger (22,88 mm) average inhibition zone than the positive control, namely mouthwash containing fenol (18,45 mm). Conclusion: Chlorine dioxide with a concentration of 0.3% has an antibacterial effect against Streptococcus mutans.
