Dental aerosol

[2] These smaller particles are capable of becoming deposited in the lungs when inhaled and provide a route of diseases transmission.

[9] The dental unit water lines (DUWLs) may also be contaminated with other bacteria like Mycobacterium spp and Pseudomonas aeruginosa.

[12] Mycobacterium tuberculosis is transmitted in the form of droplet nuclei which are smaller than 5 μm which stay suspended in the environment for longer duration.

There are lacking evidences to prove the active tuberculosis development resulting from this transmission in Dental health care Workers (DHCWs).

[17] On 16 March 2020, the American Dental Association (ADA) has advised dentists to postpone all elective procedures.

[19] Elements like calcium, aluminium, silica and phosphorus can also be found in the dental aerosols produced during the procedures like debonding of orthodontic appliances.

[21] A number of methods have been proposed, and are widely used, to control dental aerosols and reduce risk of disease transmission.
