Despite the known effectiveness of 0.2% chlorhexidine gluconate mouthwash in preventing plaque formation, relatively few studies have assessed adjunctive benefit to normal unsupervised oral hygiene measures. Furthermore, there have been few accurate measurements of toothstaining in the presence of normal oral hygiene and little data of effects on oral candidal carriage. This study was a double‐blind placebo‐controlled cross‐over study of a 0.2% chlorhexidine gluconate mouthwash used 3 times daily on plaque, staining and candidal carriage in a group of recurrent aphthous ulcer sufferers who maintained normal oral hygiene measures. At the end of 2 6‐week treatment periods, baseline plaque scores were reduced by active and placebo mouthwashes. Chlorhexidine significantly reduced plaque compared to the placebo. Staining has markedly and significantly increased during chlorhexidine rinsing. Candidal carriage was present in 22.2% of this group and there was no significant effect of chlorhexidine on the mean number of candidal colonies. The distribution of plaque and staining by tooth was plotted and observationally studied. Baseline and placebo treatment plaque distributions indicated the considerable relevance of tooth brushing behaviour for plaque distribution. The effects of tooth brushing on plaque distribution were minimised during the use of chlorhexidine. Staining associated with chlorhexidine showed a distribution again suggesting the influence of tooth brushing. In conclusion, chlorhexidine has significant adjunctive effects on plaque inhibition in the presence of normal unsupervised oral hygiene, but tooth brushing did not prevent tooth staining.
