Effect of "Awur” Tea Infusum on Mutans Streptococci

“Awur” Tea is a traditional drink of the Indonesian community that has benefits to human's health. It is known as a healthy drink since a long time ago. One of the benefits is the capability to prevent dental caries because it has active substance ,i.e tea infusum.Objectives: The aim of this research is determining the sensitivity of infusum “Awur” tea leaves on mutans streptococci, in vitro Methods:Infusum is the product of the process of steeping “Awur” tea leaves for extraction of its medicinal principles. The effect of infusum “Awur” tea was examined by measuring the inhibitory zone, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) The microorganisms tested were Streptococcus mutans Ing-Britt, Streptococcus mutans KPSK2 , Streptococcus mutans LM7, Streptococcus mutans JC2 and Streptococcus sobrinus B13. Data obtained is done by descriptive methods. Results::showed that infusum “Awur” tea has effect on all of mutans of Streptococcus mutans Ing-Britt ( inhibitory zone 2.40 mm, MIC 6.25%/ml,MBC 50%/ml), Streptococcus mutans KPSK2 ( inhibitory zone 1.80 mm, MIC 6.25%/ml,MBC 50%/ml), Streptococcus mutans LM7 ( inhibitory zone 2.00 mm, MIC 6.25%/ml,MBC 50%/ml), Streptococcus mutans JC2 ( inhibitory zone 1.60 mm, MIC 6.25%/ml,MBC 50%/ml), Streptococcus sobrinus B13 ( inhibitory zone 2.30 mm, MIC 6.25%/ml,MBC 50%/ml). Conclusion: It can be concluded that infusum “Awur” tea shows antimicrobial activity against on mutans streptococci in vitro. Hence, it may have potential anti-caries property.
