Efektivitas Suspensi Activated Charcoal dari Cangkang Kelapa Sawit terhadap Jumlah Streptococcus Mutans Pada Basis Akrilik Ortodonti

Abstract

Every year palm oil production is increasing, so there will also be an increase in palm oil waste. Palm oil solid waste produces 65 kg of shell waste per one ton of palm oil. Oil palm shells can be utilized as activated charcoal which has adsorption power against bacteria because it has a large enough surface area and porosity. Due to its adsorption properties and as an effort to reduce palm oil waste, activated charcoal can be utilized as a disinfection product in the field of orthodontics, especially the treatment of removable orthodontic appliances. The purpose of this study was to determine the difference in the mean number of colonies of Streptococcus mutans bacteria on the acrylic base of removable orthodontic appliances after being soaked in artificial saliva contaminated with Streptococcus mutans culture, 0.2% chlorhexidine solution and 10% sterile activated charcoal suspension for 15 minutes. Calculation of the number of bacterial colonies in this study using the TPC method. The research sample is a square shape self-cure acrylic base with a size of 20x20x1 mm, totaling 27 samples and divided into 3 immersion groups. One-Way ANOVA test results showed that there were significant differences in the number of bacteria in all treatment groups (p<0.05). The results of the LSD Post-hoc test, showed that there were significant differences in the number of bacteria between the artificial saliva immersion groups contaminated with Streptococcus mutans culture and 0.2% chlorhexidine, artificial saliva immersion groups contaminated with Streptococcus mutans culture and 10% sterile activated charcoal suspension, and 0.2% chlorhexidine immersion group and 10% sterile activated charcoal suspension. The conclusion of this study is that 10% sterile activated charcoal suspension has antibacterial activity against Streptococcus mutans, but not as effective as 0.2% chlorhexidine
