Abstract

controlled trial compared: Periogard® with alcohol (positive control) (CHXw/a) and without alcohol (CHXn/a); Listerine Total® (EOw/a) and Listerine ZeroTM (EOn/a) arranged into four sequences of use. 21 volunteers with intra-oral halitosis used each product at once, followed by a one-week washout period. The breath was measured by portable gas chromatograph OralChromaTM before rinsing and after 1, 2 and 3 hrs. Compared to the baseline, at the first hour, only EOw/a was able to significantly reduce the breath (H2S p<0.0001 and CH3SH p=0.001) for both gases and its effect lasted for up to three hours (H2S p<0.0001 and CH3SH p=0.001). CHXw/a (control) reduced H2S at the first hour (p=0.001) and lasted for three hours (H2S p<0.0001) without effect on CH3SH. CHXn/a just reduce H2S levels. EOn/a had no effect on breath, which increased with time for both gases. It can be indicated the essential oil based product containing alcohol and zinc chloride more efficiently with the proviso that only essential oils are approved for continuous use. The EOw/a presented the best performance against intra-oral halitosis followed by the control CHXw/a and CHXn/a.
