Abstract
BACKGROUND
Oral care regimens can be explored to improve oral health in patients with gingivitis. This study aimed to evaluate the efficacy of a multicomponent oral care regimen with a dual zinc plus arginine (DZA) toothpaste and cetylpyridinium chloride with zinc lactate (CPC + Zn) mouthwash in reducing gingival bleeding in patients with gingivitis.
METHODS
This randomized clinical trial included 94 participants with gingivitis who were randomized into two groups: the DZA/CPC + Zn group, which used a 1450-ppm fluoride toothpaste containing 0.96% zinc plus 1.5% arginine and a fluoride-containing mouthwash with 0.075% CPC and 0.28% zinc lactate, and the control group, which used a 1450-ppm fluoride toothpaste and a placebo mouthwash for 6 months. All participants were examined by a blinded examiner who measured the gingival index, plaque index, and gingival severity index. Data were analyzed using paired t test, independent t test, and analysis of covariance (ANCOVA).
RESULTS
Both groups presented statistically significant reductions in all clinical parameters compared to baseline. The DZA/CPC + Zn group exhibited significantly greater reductions in gingival index, gingival severity index, proximal gingival index, plaque index and proximal plaque index compared to the control group at 1, 3, and 6 months. Furthermore, DZA/CPC + Zn significantly decreased the percentage of patients with generalized gingivitis over a 6-month follow-up period. However, differences between the DZA/CPC + Zn and the control groups were not maintained after both groups established similar regimens with fluoride toothpaste.
CONCLUSION
The multicomponent oral care regimen consisting of DZA toothpaste and CPC + Zn mouthwash is effective in reducing gingival inflammation and supragingival biofilm in patients with gingivitis.
