ABSTRACT
Objective:
To evaluate in the vitro effectiveness of three chemical agents for toothbrush disinfection. Material andMethods:
Sixteen new toothbrushes were evaluated, previously sterilized and classified in five experimental groups (n=3) and one item as control. Three chemical agents were assessed 0.12% Chlorhexidine gluconate (CHX), essential oil mouth rinse (Listerine) and 3.5% Sodium hypochlorite (NaOCl). The five selected strains were inoculated on toothbrushes and incubated for a 24 hours period and 37°C temperature in aerobic conditions. The incubated toothbrushes were immersed for a 15 min period into selected chemical agents and after drying in a controlled air stream, again re-cultured into enriched broth. A comparison was made between the initial and final microorganisms density recovered after chemical disinfection based on Mc Farland scale. The data obtained was compared by descriptive analysis and ANOVA methodology.Results:
3.5% NaOCl was the most effective chemical agent for toothbrush disinfection followed by CHX; Listerine was not effective to eliminate the inoculated bacteria in toothbrushes.Conclusion:
3.5% NaOCl and 0.12% CHX are the most effective chemical agents for toothbrush disinfection and Listerine was only effective against C. albicans.Key words
