Abstract
Background The control of biological hazard risk in health care and dental clinic environments represents a critical point in relation to the Covid-19 infection outbreak and international public health emergency. The purpose of the present review was to evaluate the scientific literature on the no-touch disinfection procedures in dental clinics aiming to limit transmission via airborne particles or fomites using no-touch procedures for environmental decontamination of dental clinics. Methods An electronic database literature search was performed to retrieve research papers about Covid-19 and no-touch disinfection topics including full-length articles, editorials, commentaries, and outbreak studies. A total of 86 papers were retrieved by the electronic research. Results No clinical article about the decontamination of a dental clinic during the Covid-19 pandemic was detected. About the topic of hospital decontamination, we found different no-touch disinfection procedures used in hospital against highly resistant organisms, but no data were found in the search for such procedures with respect to SARS-CoV-2: (1) aerosolized hydrogen peroxide, (2) H2O2 vapor, (3) ultraviolet C light, (4) pulsed xenon, and (5) gaseous ozone. One paper was retrieved concerning SARS-CoV-2; 32 documents focused on SARS and MERS. The cleaning and disinfection protocol of health care and dental clinic environment surfaces are essential elements of infection prevention programs, especially during the SARS-CoV-2 pandemic. Conclusion The decontamination technique that best suits the needs of the dental clinic is peroxide and hypochlorous which can be sprayed via a device at high turbine speed with the ability of producing small aerosol particles, recommendable also for their low cost.

Summary
The control of biological hazard risk in health care and dental clinic environments represents a critical point in relation to the Covid-19 infection outbreak and international public health emergency. A new coronavirus emerged in the central Chinese city of Wuhan in late 2019 [1] and spread rapidly around the world [2] causing the World Health Organization to declare pandemic infection on 11 March 2020 [2] It is a coronavirus (SARS-CoV-2) that causes pneumonia, moderate to serious respiratory failure, septic shock, and higher risk of death in patients with other pathologies, especially in older people with underlying medical problems like chronic respiratory diseases, cancer, cardiovascular disease, and diabetes [1, 3]. Transmission of SARS-CoV-2 occurs mostly by respiratory droplets over a close distance It is an aerosol-transmissible disease which can spread when infected people talk, cough, sneeze, or disperse mouth and nasal fomite secretions into the air.
