Purpose: To evaluate the effects of 0.2% sodium hypochlorite, Efferdent (Prestige Consumer Healthcare), and 6.25% Ricinus communis on biofilm removal and antimicrobial action on dentures and brushes using nonimmersion or immersion protocols for the brushes.Materials and Methods: A total of 45 denture wearers were randomly assigned to a denture immersion protocol for 7 days: 0.85% saline solution for 20 minutes (control); 0.2% sodium hypochlorite for 20 minutes (SH); Efferdent for 3 minutes; or 6.25% Ricinus communis for 20 minutes (RC). The participants were also randomized to immersion (n = 23) or no immersion (n = 22) of their brushes with their dentures in the same solutions. For biofilm evaluation, the dentures were stained and photographed, and the area of the biofilm was measured using Image Tool 3.0 (University of Texas Health Science Center). To evaluate microbial load on dentures and brushes, the biofilm was collected, and the Candida spp and Streptococcus mutans colonies were counted.Results: The SH, Efferdent, and RC groups showed reduced biofilm and Candida spp on dentures regardless of the immersion protocol for the brushes. However, no difference was found in the Candida spp counts collected from the brushes immersed compared to the brushes not immersed in the solutions. The SH and Efferdent groups showed reduced S mutans on both dentures and brushes, except for in the nonimmersion subgroups.Conclusion: All solutions reduced denture biofilm and microbial load. However, immersion of brushes in the solutions did not contribute to reducing the microbial load. [ABSTRACT FROM AUTHOR] |
