title: Contamination of dental goggles and effectiveness of 3 disinfectants in a stomatology hospital.
abstract: We investigated the contamination levels of dental goggles to assess the infection risk in a stomatology hospital and compared the effectiveness of 3 disinfectants, including Swashes (Swashes Enterprise, Co. Ltd., Shenzhen, China), medical ethanol (75%), and chlorine-containing disinfectant (500 mg/L). The results showed that 87.41% of goggles had bacterial contamination. In total, 54% of cultures included gram-positive cocci, making them the major microbial group contaminating the goggles. All 3 disinfectants showed excellent performance in disinfection, and there were no significant differences among the eligibility rates of the 3 disinfectants (97.2% vs 100.0% vs 100.0%, respectively). The study highlights the fact that dental goggles are potential reservoirs of nosocomial pathogens. Disinfection of goggles could be an effective and practical infection control method for dental practice.
