Comparison Of Antibacterial Effects Between Aloe Vera And Sodium Fluoride On The Amount Of Streptococcus Mutans Colony ATCC In Vitro

Streptococcus mutans is a bacterium that plays an important role in the process of caries. These bacteria can produce glucosyltransferase GTF enzymes which can change the disaccharide particularly sucrose into glucan that serves as a medium for the initial attachment of bacteria to the tooth surface and produce acids in the metabolic process which is the beginning of dental caries. Aloe vera is natural materials that has a lot of active substances that contains antibacterial effects. Sodium fluoride is a material commonly used in the prevention of caries serves to remineralization of the teeth and has anti-bacterial properties. The purpose of this study was to analyze differences in decline in the number of colonies of Streptococcus mutans after in vitro administration of Aloe vera and Sodium Fluoride. This research was conducted using pure experimental research on the media containing artificial saliva enriched with sucrose and the culture of Streptococcus mutans ATCC 25 175 was incorporated in it. Samples are given treatments of Sodium Fluoride and Aloe vera extracts to see the difference in the number of bacterial colonies. Statistical analysisuses the t test to see a decrease in the number of colonies of Streptococcus mutans between treatment Aloe vera and Sodium Fluoride. T-test equality of two mean the two populations doesnt show a significant difference between the decline in the group of Aloe vera and Sodium Fluoride group with p-value of 0.2144. This study concludes that there is no difference in the decreasing in the number of colonies of Streptococcus mutans significantly after in vitro administration of Aloe vera and Sodium Fluoride.
