SUMMARY

The overgrowth of certain strains of normal flora in oral cavity can cause many kinds of oral infections or diseases such as carries, periodontitis, and gingivitis. Prevention and treatment of these diseases are usually achieved by chemical antiseptics. However, these chemicals are found as negative impacts of human health hazards and accession of microbial resistance. The present study explores the potential of Piper betle extracts on inhibition of two oral pathogenic bacteria; Streptococcus mutans DMST 41283 and Streptococcus intermedius DMST 42700. P. betle demonstrated significantly higher inhibitory activity against both pathogenic strains than Acacia catechu, Camellia sinensis, Coccinia grandis, Solanum indicum, and Streblus asper. Among fractionated extracts of P. betle from several solvents, the extract from ethyl acetate (Pb-EtOAc) possessed the widest inhibition zone of 11.0
