Efficacy of Turmeric Extract (Curcuma domestica Val) 40%, 50%, AND 60% CONCENTRATIONS IN INHIBITING THE GROWTH OF Streptococcus mutans bacteria
Ni Nyoman Nurdeviyanti, I Gusti Ketut Armiati, Pande Putu Levina Amanda Krisna Abstract: The oral cavity is the entrance to the bacteria that can cause the caries disease. The main bacteria cause the caries is Streptococcus mutans. The purpose of this research was to know the effectiveness of turmeric (Curcuma domestica Val) extract against the growth of Streptococcus mutans bacteria. This research is an experimental lab in vitro using the design of the post test only control group with Kirby Bauer antibacterial test at concentration of 40%, 50%, and 60% with positive control (0.2% Chlorhexidine gluconate) and negative control ( 96% ethanol). The results showed that turmeric (Curcuma domestica Val) extract with a concentration of 40% there was an average inhibition zone of 8.4 mm, in the turmeric (Curcuma domestica Val) extract with a concentration of 50% there was an average inhibition zone of 8.98mm, and in the turmeric (Curcuma domestica Val) extract with a concentration of 60% there was an average inhibition zone of 9.28 mm. Mann Whitney shown that there were not significant differences of turmeric (Curcuma domestica Val) extract at all concentration with positive control, and there were significant differences with negative control. From the research results, it can be concluded that turmeric (Curcuma domestica Val) extract can inhibit the growth of Streptococcus mutans bacteria.
