A Study on the Performance of an Oral Disinfector Based on UV-C LED Disinfection Technology

Le résumé fourni par la source

LED UV-C LED technology has garnered significant attention as a cutting-edge solution for controlling the spread of infectious and epidemic diseases. This study innovatively integrates UV-C LED technology into an oral disinfector, developing an air disinfection system based on circulating air adsorption. The system effectively captures droplets and aerosols generated during oral diagnosis and treatment, achieving efficient microbial inactivation through an integrated UV-C LED sterilization module. Non-pathogenic Escherichia coli and natural environmental bacteria were selected as test subjects to simulate real-world oral treatment scenarios and evaluate sterilization efficiency. Results show that the disinfector achieves a sterilization rate of 97.22% for E. coli and 96.24% for natural bacteria, demonstrating excellent air microbial disinfection efficacy. Additionally, to ensure safe operation, irradiance intensity was measured at three key positions (left, middle, right) around the disinfector, confirming no UV leakage risk during operation. This study represents a systematic exploration of UV-C LED disinfection technology in simulated oral clinical settings, providing critical data support for bioaerosol inactivation and offering theoretical and practical foundations for advancing infection control technologies in oral healthcare environments.
