Role of Air Cleaners in Dental Offices in India
Article by Nidhi Yadav, Bhavana Agrawal, Charu Maheshwari | Published: 2015 SRM Journal of Research in Dental Sciences
During dental treatment, several thousand droplets are aerosolized. The larger droplets fall quickly to the floor, leaving dry microscopic droplet nuclei which remain suspended in the air for extended periods of time and require prolonged hours to settle down. These bacteria and viruses become highly mobile in the air. Microorganisms in excess of that of outdoor air are present in dental surgery. The article concludes 'Due to their highly effective technology in reducing the level of bioaerosols and other advantages filters prove to be an exceptional means of controlling air borne infections in dental clinics, and hence, provide better indoor air quality'...

Important Role for Standalone Indoor Air Purification Systems in a Dental Laboratory
Article by Dental Technology Today | Published: Spring 2017
Most people do not know how harmful their indoor air can be. The US. EPA states that 68% of human disease is spread through indoor air (1). When it comes to the air in a dental laboratory, these concerns become even greater. According to the US Department of Labor’s statistics, working as dental professional is one of the most damaging jobs to people’s health (2). Why is this the case? This is due largely to the fact that many dental laboratories do not pay enough attention to their indoor air quality. Laboratory owners believe that they are well protected through...

US Dept of Labor - Indoor Air Quality Investigation
Article by US Department of Labor
This report supports the claims about Sick Building Syndrome and Building-Related Illness including the causes, toxic elements and what should be done about it.
Article by Rella Christensen, PhD Dentistry IQ Nov 111, 2006
Dental aerosols are a concern. These airborne particles are composed of debris and microorganisms propelled into the air from the oral cavities of the many people treated throughout the day within the office. These very small particles can remain suspended at the end of treatment for many hours. When inhaled, their small size allows penetration to the alveoli of the lower respiratory tract, where infectivity is greatly increased. Dentistry's invisible aerosols are inhaled inadvertently by all who enter the office - clinicians, staff, patients, people accompanying patients, service people. Today, air purifiers are not used widely in dental offices, but they are potentially a very effective way to manage aerosols. Effective equipment uses high-efficiency particulate air (HEPA) filters renewed at regular intervals.
