While dentifrices containing triclosan at 0.02% have conventionally been used in Japan, we experimentally prepared a dentifrice (SBJ-PRO2) containing triclosan at 0.3%. Thus, we planned and conducted a general clinical trial to investigate its effects in eliminating plaque and in reducing gingival inflammation. Efficacy and safety of a long-term use of dentifrices with a triclosan content of 0.3% have been reported abroad. In this study, we investigated its efficacy and safety during short-term use.
A 4-week clinical trial was conducted an 70 patients between 20 and 65 years of age. As a result, the plaque index improved by 84.1%, and the gingivitis index improved by 89.9%. Concerning safety, there were no adverse events or adverse drug reactions.
These results suggested that a dentifrice with a triclosan content of 0.3% is safe, usetul, and effective in eliminating plaque, and it provides a tool for self-prophylaxis against periodontal diseases.
