~ Treatment of Resistant Bacteria and Viruses.

 Emerging research data continue to strengthen the view that blue light in the range of 405 nm to 470 nm wavelength is antimicrobial against several bacteria. In recent studies, we showed that pulsed blue light (PBL) is not just a more potent antimicrobial than conventional blue light, but also a non-chemical and non-pharmaceutical antiviral against coronaviruses. This presentation reviews our recent studies and those of others, and summarizes our findings which show that PBL, when incorporated into dental practice, could ameliorate oral bacterial and viral infections. The paper highlights the antimicrobial value of certain light-based dental technologies and precents recent data from our ongoing studies which show that PBL-based LED light fixtures, designed for environmental sanitation, are antiviral and antibacterial against some of the deadliest bacteria and viruses. These recent findings indicate that it is possible to develop and deploy commercial cost-effective light fixtures as environmental decontaminants that can inactivate viruses and other microorganisms safely, not just in hospitals and clinics, but in homes, offices, ambulances, and other modes of transportation. The implications of these findings for disease epidemics and pandemics will be discussed.
