It contains essential oilthat can be used as an antibacterial agent. Streptococcus sanguis is the first colonial form bacteriathat causes dental plaque, the cause of dental caries and calculus. Inhibition of antibacterial is theability to inhibit bacteria growth. Essential oil has bacterial inhibition to damage the bacteria cellmembrane and enzyms. Purpose. To find out the inhibition of Piper retrofractum Vahl extract on thegrowth of Streptococcus sanguis. Method. The method used in this study was antimicrobial test ofdilution with concentration of 100%, 90%, 80%, 70%, 60% and 50%. Piper retrofractum Vahl extractmixed with Brain Heart Infusion Broth (BHIB) to obtain each consentrations then Streptococcussanguis added and incubated for 24 hours. Observations made by visual observation and streaking onTryptone Yeast Cystine (TYC) agar. Results. Minimum Inhibitory Concentration (MIC) of PiperRetrofractum Vahl extract against Streptococcus sanguis, based on observations of the growth ofbacteria on media BHIB and TYC agar, was 70%. Conclusion. Piper retrofractum Vahl extract inhibitthe growth of Streptococcus sanguis in wich is 70 %.
