Quantitative measurements of aerosols from air-polishing and ultrasonic devices: (How) can we protect ourselves


Kaufmann, Manuela; Solderer, Alex; Gubler, Andrea; Wegehaupt, Florian J; Attin, Thomas; Schmidlin, Patrick R (2020). Quantitative measurements of aerosols from air-polishing and ultrasonic devices: (How) can we protect ourselves. PLoS ONE, 15(12):e0244020.

Abstract

Aim: To assess the distribution and deposition of aerosols during simulated periodontal therapy.
Methods: A manikin with simulated fluorescein salivation was treated by four experienced dentists applying two different periodontal treatment options, i.e. air-polishing with an airflow device or ultrasonic scaling in the upper and lower anterior front for 5 minutes, respectively. Aerosol deposition was quantitatively measured on 21 pre-defined locations with varying distances to the manikins mouth in triplicates using absorbent filter papers.
Results: The selected periodontal interventions resulted in different contamination levels around the patient's mouth. The highest contamination could be measured on probes on the patient's chest and forehead but also on the practitioner's glove. With increasing distance to the working site contamination of the probes decreased with both devices. Air-polishing led to greater contamination than ultrasonic.
Conclusion: Both devices showed contamination of the nearby structures, less contamination was detected when using the ultrasonic. Affirming the value of wearing protective equipment we support the need for universal barrier precautions and effective routine infection control in dental practice.
