title: A comparative study in vivo of the therapeutic effect of triclosan, hexetidine and chitosan.
abstract: The present clinical study was performed to comparatively assess the therapeutic effect of Low and High Molecular Weight Chitosan (LMWCh and HMWCh), hexetidine, triclosan. Plaque index, saliva buffering capacity and bacteriological controls for S. mutans and lactobacilli, were performed. The plaque and bacterial indices revealed statistically significant differences between groups. Buffering capacity was similar using, hexetidine, and triclosan, whereas it was maximum in 100% of the patients in the LMWCh and HMWCh groups. Only 0.5% HMWCh induced low activity of S. mutans in 100% of the patients and caused complete inhibition of lactobacilli growth. No changes were observed in the profile of salivary proteins. The present clinical study confirms the therapeutic efficacy of the chitosan as a bacteriostatic agent.
