tailieunhanh - In vitro antimicrobial activity of some commercial toothpastes
Despite great improvements in global oral health status, dental caries still remain one of the most prevalent diseases. Yet some brands of toothpastes claim to be effective antimicrobial agents. This study was therefore designed to evaluate the in vitro antimicrobial activity of commercially available toothpastes against some microorganisms involved in tooth infections. Agar disc diffusion method was used to test the antimicrobial activity of ten different toothpastes at various concentrations (1:2; 1:4 and 1:8 dilutions) against Porphyromonas gingivalis, Escherichia coli, Staphylococcus aureus and Candida albicans. The sensitivity of tested toothpastes towards each microorganism was expressed as a percentage of the mean clear zone diameter. | In vitro antimicrobial activity of some commercial toothpastes
