Abstract
Dentists, dental hygienists and oral health care workers practice in a highly sensitive environment with marked contamination where they are exposed to a variety of bacteria, viruses, fungi and protozoan from many sources 1. Transmission of infection during any dental treatment can occur through different routes such as direct contact with blood, saliva or tissue debris, indirect contact with contaminated instruments or surfaces that are improperly sterilized or contact with infective agents present in either the droplets or aerosol particles from saliva and respiratory fluids.2 During dental treatments, saliva may become aerosolized and microorganisms from the mouth will contribute to the spread of infection.3 Dental handpieces, ultrasonic scalers, air polishers and air abrasion units produce the foremost visible aerosols. Each of these instruments produces an aerosol from the operative site by the action of the rotary instrument, ultrasonic vibrations or the combined action of water sprays and compressed air. Aerosol transmission is one of the possible modes of contamination when there is exposure to high concentrations of aerosols in a relatively closed environment. Routine dental procedures generate aerosols that can pose potential risks to the dental care personnel and also to the patients. Dental teams should be well aware of the risks and maintain a healthy environment for preventing such infections. Therefore, understanding aerosol transmission and its implications in dentistry are essential. In addition to standard precautions, some special precautions should also be implemented. 4 Bacterial species like Pseudomonas aeruginosa, Pseudomonas cepacia, Legionella pneumophila and Mycobacterium chelonae are identified in biofilms in dental clinics.5 The concentration of total bacterial aerosols is said to clinical working hours in dental surgeries.6 The emergence of the novel coronavirus disease 2019 (COVID-19) caused by the highly infectious SARS- CoV-2 virus at the end of 2019 led the World Health Organisation (WHO) to declare a global pandemic on 11 March 2020.7
