Introduction: Reduction of biofilm on dentures is important for maintaining denture wearersâ€™ health.
Objective: The aim of this study was to assess the effectiveness of toothbrush handles individually adapted in reducing of biofilm on dentures.
Materials and Methods: Study participants were 16 residents of the condo for the elderly, denture wearers, functionally independent and without cognitive impairment. Participants were randomly divided into two groups: Group 1 (adapted toothbrush handles) and Group 2 (conventional toothbrush). Biofilm from the inner surface of the basal area of the denture was observed using 5% erythrosine. Images obtained before starting the use of toothbrushes, after 7 and 21 days were sent for computer analysis.
Results: The average amount of biofilm on the first day was considered severe in both groups. At the end of the experiment, the average biofilm coverage in Group 1 was 44.7% (13.1% reduction) and in Group 2 it was 48.6% (4.8% reduction). However, the Friedman analysis of variance test showed that the reduction was statistically significant (p< 0.05) only in Group 1, demonstrating the effectiveness of the adapted brushes.
Conclusion: The findings of this pilot study indicated that for the reduction of biofilm on dentures the adapted toothbrush handles were superior to the conventional type.
