Clinical Trial Summary

A desirable quality of mouthrinses is substantivity an intrinsic feature of some molecules. Substantivity requires the adsorption of the agent on the oral surfaces and subsequently antimicrobial activity bacteriostatic along following hours. This work aims to quantitatively determine the substantivity of (i) a single o-Cymen-5-ol plus CPC oral rinse, (ii) a, CPC oral rinse and (iii) a o-Cymen-5-ol mouthwash on the salivary microbiota up to 4 h after their application.

Description:

One of the desirable qualities of mouthrinses is substantivity, which is defined as the persistence capacity of its antimicrobial action over time in the mouth. This is an intrinsic feature of some molecules. Such substantivity seems to require the adsorption of the agent on the buccal surfaces and subsequently exert a certain antimicrobial activity that seems to be mostly bacteriostatic. Substantivity is the result of multiple factors controlling or altering adhesion, life period of antimicrobial capabilities, synergisms, antagonisms, and others. In order to improve substantivity and therefore increase antimicrobial effectiveness of CPC, o-Cymen-5-ol has recently been proposed to become incorporated to oral rinses. The aim of this work is to quantitatively determine the substantivity of (i) a single o-Cymen-5-ol plus CPC oral rinse, (ii) a, CPC oral rinse and (iii) a o-Cymen-5-ol mouthwash on the salivary microbiota up to 4 h after their application.
