Abstract

Purpose: Evaluation of the bacterial contamination of toothbrushes, and comparing the antibacterial effect of microwaves radiation, ultraviolet radiation, and Chlorhexidine gluconate on toothbrushes among children. Subjects and methods: Twenty-seven normal apparently healthy children aged between 6-12 years from both genders were involved in this study and equally divided into three groups regarding the technique of toothbrush sterilization. Group I: included children’s toothbrushes were exposed to microwave radiation for 3 minutes. Group ІІ: included children’s toothbrushes were exposed to UV radiation for 12 minutes. Group ІІІ: included children’s toothbrushes were immersed in chlorhexidine mouthwash 0.12% for 20 hours. All toothbrushes were collected after the children were instructed to brush their teeth with them for one week twice daily. Results: Significant decrease in overall bacterial count across the three study groups after toothbrush sterilization. However, when compared with ultraviolet and microwave radiation, chlorohexidine demonstrated a significantly lower overall bacterial count. and there was a substantial difference between the three groups in terms of statistics. Conclusion: This study proved efficacy for the reduction of total bacterial count after sterilization of toothbrushes with chlorhexidine having the highest reduction rate among the three studied groups.
