A Review on the Current Trends to Reduce Exposure to Bioaerosols in Operative Dentistry

Abstract

Aerosols and dentistry always go hand in hand. Aerosols are particles less than 50 μm in diameter and dentists are at high risk of infectious airborne diseases due to these aerosols. They are produced as a result of dental procedures using high speed handpiece, ultrasonic units, three way syringes etc. Covid -19 pandemic has fabricated new challenges to health care providers and increased their responsibilities towards society. During this time of crisis it is necessary for the dental professionals to safeguard themselves and also offer timely treatment to their patients. The current pandemic has opened a wide arena for additions and changes in the way dentists previously worked. Physical barriers such rubber dams, specially designed chambers and protective acrylic screens are used to avoid direct contact with aerosols. Air purification, filtration units along with fumigation and ventilation can be used to reduce the microbial load in air circulating within the operatories. This article reviews the current trends that are available to reduce bio aerosols in dental operatories that can be practically employed in day to day practice.
