In the present study, three tooth paste samples Colgate, Sensodyne and Himalaya have been taken. This experiment show Sensodyne have good antimicrobial activity against S.aureus than in Colgate and Himalaya. Colgate total contains which kills a wide range of bacteria. From these studies we conclude Himalaya is showing good DPPH radical scavenging activity at 90 min. This may be due to high phenolic content in Himalaya. Based on the polyphenol estimation, the phenolic content in Himalaya is high. Superoxide scavenging assay shows that Sensodyne it is 95.38%, for Himalaya, 63.59% and for Colgate it is 69.78%. All the paste samples are having no effect on squamous epithelial cells.
