Chlorhexidine mouthrinse as an adjunctive treatment for gingival health

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effectiveness of chlorhexidine mouthrinse used as an adjunct to mechanical oral hygiene procedures (i.e. toothbrushing with/without the use of dental floss and/or interdental cleaning aids) for the control of gingivitis and plaque compared to: mechanical oral hygiene procedures alone mechanical oral hygiene procedures plus placebo mouthrinse mechanical oral hygiene procedures plus mouthrinses containing other plaque inhibitory, anti‐plaque or anti‐gingivitis agents mechanical oral hygiene procedures plus mouthrinses containing different formulations of chlorhexidine. To determine whether the effect of chlorhexidine mouthrinse is influenced by chlorhexidine concentration, or frequency of rinsing (once/day versus twice/day). To report and describe any adverse effects associated with chlorhexidine mouthrinse use (reporting of adverse effects will be limited to those detailed in the included trials).
