The air evacuated from the dental environment also first goes through a high-efficiency pre-filter and then is treated with high-powered, UV-C radiation to destroy virus particles. The Mi Dentista dental team has also implemented other infection control methods recommended by the CDC and the American Dental Association including avoiding placing patients in an enclosed waiting room, no accompanying visitors, repeated disinfection of surfaces during the day, and frequently replacing masks, face shields, gowns, goggles, and gloves. “ “Consider the use of upper-room ultraviolet germicidal irradiation (UVGI) as an adjunct to higher ventilation and air cleaning rates.” The use of these units will reduce particle count (including droplets) in the room…. “Consider the use of a portable HEPA air filtration unit while the patient is actively undergoing, and immediately following, an aerosol-generating procedure. “Ventilation systems that provide air movement from a clean (DHCP workstation or area) to contaminated (clinical patient care area) flow direction should be installed… ,” CDC COVID-19 Guidance for Dental Settings (Updated on May 19, 2020). Yet, without similar support, dentists and dental assistants may have a higher chance of becoming infected and transmitting the disease to others. The negative pressure approach is the same method that large, specialized hospitals use to prevent the transmission of many airborne pathogens like tuberculosis and measles in the form of negative pressure isolation rooms. Most importantly, as you can see in the video below, the air around the treatment care area, namely the oral region where dental procedures are carried out, is being constantly replaced and refreshed without interruption. In addition, due to the 6000 CFM rating of the multiple reverse flow fans, the air across the entire dental office may be replaced every 90 seconds. Each unit’s reverse flow fan is rated to evacuate up to 2100 CFM (cubic feet of air per minute) which means that the quiet, powerful system may replace the air around every dental unit every 20 seconds. Mi Dentista has set up elegantly-designed high-efficiency negative pressure dental units so that both droplets and aerosols may be rapidly eliminated via a high-speed vacuum. ![]() Thus, the physical proximity between patients and dentists during a typical dental visit may benefit from additional care and attention. Novel coronavirus, as the virus is frequently known, is believed to spread via droplets or aerosols produced from coughing, dental procedures, and breathing among others. Mi Dentista Dental Clinic in collaboration with a mechanical engineering firm, HVAC Engineering, has set up the first known dental clinic in Los Angeles that uses Negative Pressure Environments to mitigate diseases like COVID-19, namely the disease associated with the SARS-Cov-2 virus. ![]()
