    Abstract

    Purpose

    The purpose of this study was to evaluate, in vitro, the contamination of toothbrushes and pacifiers by Streptococcus mutans, and the efficacy of microwave and chlorhexidine for their disinfection.

    Materials and methods

    Sixty pacifiers and 60 toothbrushes were contaminated with S. mutans and then divided into groups according to the disinfection protocol: Group 1—chlorhexidine solution; group 2—microwave sterilization; and group 3—sterile tap water. The devices were evaluated microbiologically after disinfection for the survival of S. mutans colonies and were examined. The results were analyzed statistically by ANOVA and Turkey test.

    Results

    The results of both types of evaluation showed a large number of S. mutans colonies after spraying with sterile tap water, and chlorhexidine spraying and microwaving were effective in eliminating colonies. Groups 1 and 2 were statistically similar to each other (p > 0.05) and differed significantly from group 3 (p < 0.05).

    Conclusion

    The 0.12% chlorhexidine solution spray and 7 minutes of microwave irradiation were almost equally effective for disinfection of pacifiers and toothbrushes.
