Aerosol Generating Procedures (AGPs) in dentistry include any procedure that uses any of the following devices: high speed hand pieces, surgical hand pieces, ultrasonic and sonic devices, air polishing devices, and lasers. Triplex where air and water are used together or used with air on a wet surface is onsidered aerosol generating.
All patients are to be screened upon arrival at the clinic. The latest screening questions can be found at
COVID-19 screening at NSW healthcare facilities and usually consist of the following:
All dental practitioners should exercise clinical judgment with consideration of current local epidemiology, NSW Health advice, protocols, risk level, as well as the nature of the dental procedure being performed. This will assist in determining whether to delay or defer treatment. Consideration should be given to the seriousness of the presenting condition, and to the patient's COVID-19 status (i.e. low risk, confirmed, or suspect).

Implement aerosol management. Use isolated areas, single rooms with door closed where available, negative air flow and ventilation. High risk AGPs consider negative pressure rooms or equivalent.
Aerosol Generating Procedures (AGPs) in dentistry are defined as procedures that use any of the following devices: high speed hand pieces, surgical hand pieces, ultrasonic and sonic devices, air polishing devices, and lasers. Triplex - where air is used together with water, or air is used on a wet surface - is considered aerosol generating.
*Risk assessment for AGPs should consider the length of procedure and anticipated exposure to large volumes of blood/body fluids and respiratory droplets and prevalence of community transmission.
**Public Health Risk and alert phases are based on direction from Public Health response branch (PHRB) and the NSW Health Clinical Excellence Commission (CEC) further information can be found the on the Critical Intelligence Unit website and on the
