    Abstract:
    OBJECTIVES: The aim of the study was to compare the gingival health benefits of a thiocyanate/carbamide peroxide toothpaste to that of a triclosan toothpaste in home use. MATERIALS AND METHODS: The study was a two-centre, randomised, double-blind, parallel-group clinical trial, and consisted of a 2-week pre-experimental phase, followed by an experimental period of 6 months. A total of 140 healthy male and female volunteers (70 per group) who had at least 20 natural teeth with no probing depths greater than 5 mm and a mean gingival index (GI) of 1 or more at screening were admitted to the study. The two products were the test toothpaste (RCP) containing 0.5% SCN- (rhodanide), carbamide peroxide (equivalent 0.1% H2O2), and 1450 p.p.m. fluoride, and a control toothpaste (Colgate Total) containing 0.3% triclosan, 2.0% polyvinyl methyl ether maleic acid (PVM/MA), and 1450 p.p.m. fluoride (Triclosan). In the pre-experimental phase, all subjects used a fluoride toothpaste. Plaque (Turesky et al. 1970) and gingivitis (Löe & Silness 1963) were scored prior to beginning the pre-experimental phase, at baseline, and after 6 weeks and 3 and 6 months. RESULTS: In both the RCP and the Triclosan group, gingival health improved significantly between baseline and the following examinations. Plaque scores decreased significantly between baseline and 6 months in both groups. There were, however, no significant differences between the groups for either gingival index or plaque index. CONCLUSION: To conclude, this study seems to verify that in normal home use, a toothpaste containing a combination of thiocyanate and carbamide peroxide is as effective in reducing gingival inflammation and supragingival plaque formation as a benchmark control product.
