An in vitro evaluation of the availability of cetylpyridinium chloride and chlorhexidine in some commercially available mouthrinse products

This study highlights the fact that some commercially available mouthrinses may not achieve the plaque inhibitory activity that they are expected to have.Ingredients contained within some cationic antiseptic mouthrinse solutions may inactivate the plaque inhibitory agent.The study confirms the varying ability of different mouthrinses to form stains in the laboratory and this has been found in many previous studies to be indicative of clinical staining and plaque inhibitory efficacy.
