ABSTARCT Background: Dental plaque is a soft layer consist of the accumulation of bacteria, formed and attached to the tooth surface. Propolis (Apis mellifera) contain flavonoid which is known as an antibacterial compound. The content of tt-farnesol and apigenin in flavonoids have a high potential as an anti-Streptococcus mutans and inhibit glucosyltransferase activity. Research objective: To find the influenceof propolis(Apis mellifera) hardcandyconsumption toward the decrease of dental plaquescores. Research methodology: This research is a clinical experimental research using a pretest-posttest design. Subjects were recorded their initial dental plaque scores, then consume propolis (Apis mellifera) hard candy and subjects dental plaque were re-scored. The statistic alanalysis test applies paired t-test. Research findings: The research finding shows the mean scores of dental plaque before is 0.47 and after is 0.36 which has 0.10 differences plaque scores with SD (Standar Deviation)  0,15 and  0,17 respectively. Conclusion : Propolis (Apis mellifera) hard candy consumption has the influence toward the decrease of dental plaque scores.
