Antimicrobial Effect of Tea and Tea with Milk Beverages on Oral Streptococcus mutans and Lactobacilli

The aim of this study was to compare the antimicrobial effects of black tea to that of tea with milk (TM) against oral Streptococcus mutans and Lactobacillus sp. in Egyptian children. Three saliva samples were obtained from children (pre, immediately post and after 1 hour of beverage drinking) by spiting in sterilized containers. The samples were added to transporting media and transmitted to bacterial lab for culturing and counting. The results showed that tea and TM beverages had a highly significant bacterial counts reduction against these cariogenic bacteria by different rates (43.6% - 83.3%). Conclusions; tea and TM exhibited a magnificent antimicrobial effect against S. mutans and Lactobacillus bacteria. Consequently, they are recommended as effective natural anti-cariogenic beverages.
