The making of dentures is carried out as an effort to deal with tooth loss in the community. Heat polymerized acrylic resin is the most commonly used material for removable dentures. Dentures need to be cleaned regularly to avoid the growth of Streptococcus mutans. Peppermint leaf has antibacterial activity due to the presence of compound such as menthol, menthone, flavonoids, polyphenols, tannins, saponins, and alkaloids. The purpose of this research is to examine the effect of peppermint leaf extract on the growth Streptococcus mutans of heat polymerized acrylic resin.
Laboratory experimental research was carried out on acrylic resin discs with a diameter of 10 mm and a height of 2 mm. The research subjects were soaked in artificial saliva for 1 hour, then soaked in Streptococcus mutans suspension for 24 hours. The research subjects were divided into five groups: positive control group (0.5 % sodium hypochlorite), negative control group (aquadest), and groups soaked in peppermint leaf extract at concentrations of 5%, 10%, and 20%. Each group was soaked for 30 minutes. Spread plates method was used in bacteria inoculation and colony counter was used to count colony of Streptococcus mutans. Data were analyzed using One Way ANOVA and LSD.
The results showed the highest mean of colonies in the negative control group (274 x 10² CFU/ml) and the lowest mean of colonies in positive control group with 6.4 x 10² CFU/ml, followed by the peppermint leaf extract group with a concentration of 20% (65.4 x 10² CFU/ml). One Way ANOVA and Post-Hoc LSD test showed that there are significant differences (p<0>Streptococcus mutans and the 20% concentration of peppermint leaf extract has the highest power to inhibited the growth of Streptococcus mutans, but its effectiveness was still lower compared to 0.5% sodium hypochlorite.
