Abstract

Background: Dental caries is caused by Streptococcus mutans, which forms biofilms and produces acid that damages tooth enamel. Prevention is often achieved through mouthwashes containing antibacterial agents, but commercial products may have side effects due to chemical ingredients. Artocarpus altilis (breadfruit) leaves contain bioactive compounds like flavonoids and tannins, which have potential as natural antibacterial agents. Objective: This study aimed to evaluate the antibacterial activity of Artocarpus altilis leaf extract and formulate an effective mouthwash against Streptococcus mutans. Methods: The study used a true experimental design with a pretest-posttest control group. The extract was obtained by maceration with 96% ethanol. Three mouthwash formulations were prepared with varying glycerin concentrations (15%, 20%, and 25%). Antibacterial activity was assessed using the paper disk method, and data were analyzed using Kruskal-Wallis and Mann-Whitney tests. Results: The 2-4% extract had strong antibacterial activity, with inhibition zones ranging from 20.25–23.81 mm, significantly different from the negative control (p<0.05). The mouthwash formulations were liquid, yellow-green in color, with a characteristic breadfruit and mint scent, pH ranging from 5.5 to 7.9, and viscosity of 1 cPs. The mouthwash exhibited strong antibacterial activity, with inhibition zones between 18.81±1.5 mm and 18.94±0.5 mm, showing no significant differences across formulas (p>0.05). Conclusion: The 2% Artocarpus altilis extract and 15% glycerin formula was stable and effectively inhibited Streptococcus mutans

Abstract

Black rice (Oryza sativa L.) contains chemical compounds, namely ferulic acid, -oryzanol, amino acids, tannins, phenolics, and anthocyanins which have potential as antibacterial agents. This study aims to formulate an antibacterial gel preparation from black rice extract with an extract concentration of 10% and to test the antibacterial effectiveness of the gel preparation against Staphylococcus aureus and Escherichia coli bacteria. Black rice extract was obtained by maceration using 70% ethanol solvent: 3% citric acid. The extract obtained was then formulated in a gel dosage form. The results showed that black rice extract could be formulated as an antibacterial gel preparation that met the organoleptic, homogeneity, pH, spreadability, and adhesion requirements. In the results of the antibacterial effectiveness test, there is a clear zone which represents the ability to inhibit the growth of the tested bacteria by the gel. Black rice extract can be formulated in a gel dosage form with an extract concentration of 10% and a physically stable formula is obtained in formula III with a carbopol concentration of 2%. The average diameter of the antibacterial gel FIII preparation of black rice extract in inhibiting Staphylococcus aureus bacteria was classified as strong, namely 11.17 ± 0.34 mm, while inhibition of Escherichia coli bacteria was also relatively strong, namely 12.20 ± 0.46 mm
