The 24th CE Leader of the Year

As dentists and other healthcare providers continue to respond to the COVID pandemic and emerging variants, an easy-to-use tool is now available to help them easily and accurately assess the ventilation rate of treatment rooms and waiting rooms.

The Eastman Institute of Oral Health Research published in the "Journal of Dentistry" showed that if the ventilation rate of the room is low, the respiratory aerosol particles will stay in the indoor air for a long time. Minimize the potential exposure of airborne viruses (such as COVID) to patients and providers.

As part of the University of Rochester Medical Center, the Eastman Institute of Oral Health has developed a calculator and a simple process and other tools to help dentists easily determine the ventilation rate of any room in terms of air changes per hour measure.

"Knowing the ventilation rate of each dental treatment room will help providers understand what measures they can take to improve ventilation when necessary," said Professor EIOH, DDS, PhD, MPH, who provides research on dental treatment, aerosol behavior and Ventilation was widely cited throughout the pandemic.

"We found that the carbon dioxide level in the dental treatment room is directly related to the ventilation rate and the number of people in the room," said Dr. Ren. The research-the basis for the development of the ventilation calculator-was published in the Journal of Dental Research.

Using carbon dioxide monitors and household baking soda and vinegar, suppliers can follow a process that includes calculators suitable for imperial or metric measurements to determine the room’s current air change rate. These tools, video demos, and email addresses for sending questions are available on the EIOH Covid Security and Resources webpage.

Due to the wide variety of procedures performed by dentists, which often produce splashes, droplets and aerosols, the Eastman Institute of Oral Health adopted the CDC's recommendations and formulated an increase in the ventilation rate of its dental treatment room to 15 times per hour The strategy of breathing.

"Many factors affect the ventilation rate of any given room, including the HVAC system, the size and design of the room, and the structure and age of the building," said Dr. Ren. "Improving room ventilation is as simple as adding a portable air purifier."

When adding a portable air purifier, it is important to understand its clean air delivery rate to ensure that it helps achieve the required air exchange rate. The EIOH Covid Safety and Resources website also provides guidance and custom tools to help users understand the clean air delivery rate and how to calculate the air exchange rate of their portable air purifier.

“The higher the clean air delivery rate, the faster the portable air purifier can clean the air,” explained Dr. Ren. "When choosing a portable air purifier for a dental treatment room, please use the tobacco smoke grade, which represents the size of the most difficult small dental aerosol to clean."

Improved ventilation and air filtration are important steps in a multi-level approach to safely providing dental care during a pandemic of infectious respiratory diseases. Pre-appointment screening for signs and symptoms, proper body distance, preoperative mouthwash, proper use of personal protective equipment including N95 masks and protective glasses or face masks, and thorough disinfection and cleaning are all important steps to prevent potential transmission. COVID-19 in the dental environment.

The Eastman Institute of Oral Health at the University of Rochester Medical Center was established in 1917. It is a world leader in research, post-doctoral education, and clinical care, and has consistently ranked among the top 10 NIH/NIDCR-funded companies.
