Abstract

Aim: To investigate whether the use of an oxidizing mouth rinse as an adjunct to chlorhexidine is efficacious in reducing stains and plaque.

Materials and methods: This study had a single-blind, three-group (n = 35 each) parallel design, including a 21 days experimental period during which group I rinsed with chlorhexidine (CHX) 0.2% alone, group II used chlorhexidine (CHX) followed by hydrogen peroxide (H2O2) 1.5%. Group III rinsed with the same mouthwashes in reverse order. Patients were randomly assigned to one of the three groups. The examination for plaque, and stains was done after 1, 2, and 3 weeks of rinsing.

Results: Group II showed significantly less stain intensity in comparison with group I after 14 and 21 days (P values 0.025 and 0.005, respectively). The proportion of stained surfaces was less in the group II than in the group I and was significant at the end of 1 week. The plaque formation was significantly less in groups II and III than group I at 7, 14, and 21 days.

Conclusion: The adjunctive use of hydrogen peroxide to chlorhexidine proved to be superior to chlorhexidine alone with regard to the inhibition of plaque and development of stains.

Keywords: Chlorhexidine; hydrogen peroxide; plaque; stain area; stain intensity.
