Comparing the Effect of 0,06 % -, 0,12 % and 0,2 % Chlorhexidine on Plaque, Bleeding and Side Effects in an Experimental Gingivitis Model. A Parallel, Double Masked, Randomized, Placebo-controlled Clinical Trial
Chlorhexidine is the gold standard of dental plaque prevention, but which concentration is the most effective is not known. The aim of the present study was to compare the plaque and gingivitis inhibiting effect of commercial products containing 0.2%, 0.12% and 0.06% chlorhexidine in a modified experimental gingivitis model. In three groups of healthy volunteers, experimental gingivitis was induced and monitored over 21days, simultaneously treated with the commercial solutions containing 0.2%, 0.12% and 0.06% chlorhexidine. The maxillary right quadrant of each individual received mouthwash only, whereas the maxillary left quadrant was subject to both rinsing and mechanical oral hygiene. Compliance and side effects were monitored at days 7, 14, and 21. Plaque and gingivitis scores were obtained at baseline and day 21. The commercial mouthwash containing 0.2% chlorhexidine resulted in statistically significantly lower plaque scores than the 0.12 and 0.06% mouthwashes after 21 days use, whereas no statistically significant difference was found between the effect of the two latter mouthrinses. A commercial available mouthwash containing 0.2% chlorhexidine proved statistically significant better effect in preventing dental plaque than 0.12% and 0.06% solutions.

- Plaque index of Silness and Loe (PI) 1964 — 21 days
0= No plaque 1. A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may be seen in situ only after application of disclosing solution or by using the probe on the tooth surface. 2. Moderate accumulation of soft deposit s within the gingival pocket, or the tooth and gingival margin which can be seen with the naked eye. 3. Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin.
