| dc.description.abstract | Stick of microbial on the surface of dentures can cause proliferation of bacteria colony so it cause the formation of plaque that can cause bad smell in mouth and denture stomatitis. There is evidence that denture stomatitis also cause by another species biofilm, that is Streptococcus mutans. This study was aimed at observing the differences of Anacardium Occidentaleleaf extract efficacy as denture cleanser in concentration of 25%,50%, 75% for 45 minutes on the growth of S. mutans. The samples were made from heat-cured resin acrylic plates with dimension of 10 x 10 X 1 mm. Heat-cured resin acrylic plates were immersed in Anacardium Occidentaleleaf extract with concentration of 25%,50%, 75% for 45 minutes which each concentration contained of 8 samples, and heat-cured resin acrylic plate were immersed in the aquades as control. To observe the inhibiting force of Anacardium Occidentale leaf extract on the growth of S. mutans, it was tested using spectrometer. The data were analyzed using one way ANOVA. The result showed that there were significant differences (p < 0.05). Then the data were analyzed using LSD test and it showed that there were significant differences on heat-cured resin acrylic plates immersed in Anacardium Occidentale leaf extract with concentration of 25%,50%, 75% for 45 minutes on the growth of S. mutans. In conclusion, Anacardium Occidentaleleaf extract in concentration of 75% used to immerse the acrylic plate for 45 minuts efectively inhibited the growth of S. mutans. | en_US |
