Biocidal activity of chlorhexidine and cetrimide against various oral microorganisms

ABSTRACT

The microbicidal activity of chlorhexidine and cetrimide alone and in combination against various oral microorganisms was evaluated. The tested microorganisms were Staphylococcus aureus, Strept. viridans, Lactobacilli and C and ida albicans. The results showed that cetrimide [0.025%] potentiated the activity of chlorhexidine, and it was possible to select combinations that produce a 100% kill within five minutes. Such formulations could be of use as mouth rinses to guard against dental caries and other oral diseases such as c and idosis
