Environmental Disinfection of a Dental Clinic during the Covid-19 Pandemic: A Narrative Insight.

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.

Impact of COVID-19 pandemic on otolaryngology, ophthalmology and dental clinical activity and future perspectives.

OBJECTIVE: Since the COVID-19 outbreak, otolaryngologists, ophthalmologists and dentists have been severely affected, both for the transmission routes and for the diagnostical and therapeutic procedures typical of these disciplines. MATERIALS AND METHODS: In this article, we discuss the transmission routes, the potential risk of contagion for patients and healthcare providers during procedures, and comment on the changes that will affect head and neck clinical practice in the future of outpatient and surgical activities. RESULTS: Otolaryngologists, ophthalmologists and dentists are at high risk for infection contagion and spread because they perform diagnostic and therapeutic procedures that generate aerosol and droplets thus facilitating virus transmission. Furthermore, examination involves close doctor-patient contact and otolaryngologists and dentists have to remove patient's protective devices during the visit. CONCLUSIONS: Special attention to prevention protocols for diagnostic and therapeutic procedures and the use of protective equipment is of utmost importance to limit contagion and prevent a new virus spread in the near future.
