A Study on the Deodorant Effect of Dentifrices Containing Chlorhexidine

The effect of chlorhexidine (CHX) -containing dentifrice on bad breath suppression was determined. In the in vitro test, reacting the dentifrice with the mixed saliva, we measured sulfur compounds. The amount of sulfur compounds of the CHX-containing dentifrice group was low, and this result was statistically significant (p<0.01). In the clinical test in which the subjects used each dentifrice continuously for four weeks, sulfur compounds of the CHX dentifrice group were reduced by 51.8%. Moreover, the rate of debris suppresion in the CHX dentifrice group was higher than in the control dentifrice group.
