Abstract

• Objective: The objective of this single-center, double-blind, parallel-group, randomized six-month clinical study was to evaluate the clinical efficacy of a new Dual Zinc plus Arginine dentifrice (Colgate-Palmolive Co., New York, NY, USA) containing zinc (zinc oxide, zinc citrate) 0.96%, 1.5% Arginine, and 1450 ppm fluoride as sodium fluoride in a silica base in reducing established dental plaque and gingivitis over a six-month period, relative to that of a regular fluoride dentifrice containing 1450 ppm fluoride as sodium fluoride in a silica base (Colgate-Palmolive Co., New York, NY, USA). • Methods: A total of 100 adult male and female subjects from Santo Domingo, Dominican Republic were enrolled in this clinical study. During the baseline visit, the dental examiner clinically measured three gingival parameters (gingival index, gingival severity index, gingival interproximal index) and three plaque parameters (plaque index, plaque severity index, plaque interproximal index). The examining clinician also performed an assessment of the oral soft and hard tissues. All subjects were then assigned a subject identification number in chronological order from 001 to 100 and were randomly assigned to one of two treatment groups following a computer-generated randomization list. They were provided with their assigned dentifrice and an adult, soft-bristled toothbrush for home use, and were instructed to brush twice daily (morning and evening) for one minute with the assigned dentifrice for a period of six months Subjects returned to the study facility site for their follow-up evaluation of plaque and gingivitis parameters after three and six months. • Results: Ninety-six (96) subjects completed the study. At the three-month evaluation, subjects in the Dual Zinc plus Arginine dentifrice group exhibited statistically significant (p < 0.001) reductions in all gingival and plaque parameters relative to subjects in the fluoride dentifrice group. For gingival parameters, reductions were 18.8% for gingival index, 33.3% for gingival severity index, and 19.1% for gingival interproximal index. For plaque parameters, reductions were 11.0% for plaque index, 22.4% for plaque severity index, and 9.8% for plaque interproximal index. At the six-month evaluation, subjects in the Dual Zinc plus Arginine dentifrice group presented continuous statistically significant (p < 0.001) reductions in all three gingival and plaque parameters when compared to the subjects in the fluoride dentifrice group. For gingival parameters, reductions were 26.3% for gingival index, 56.6% for gingival severity index, and 29.2% for gingival interproximal index. For plaque parameters, reductions were 30.1% for plaque index, 61.9% for plaque severity index, and 28.0% for plaque interproximal index after six months of product use, • Conclusions: The overall results of this double-blind clinical study support the conclusion that a Dual Zinc plus Arginine dentifrice containing zinc (zinc oxide, zinc citrate) 0.96%, 1.5% Arginine, and 1450 ppm fluoride as sodium fluoride in a silica base provides significantly greater reduction in dental plaque and gingivitis parameters as compared to a regular fluoride dentifrice containing 1450 ppm fluoride as sodium fluoride in a silica base after three months and six months of product use.
