As concern about indoor air quality increases, attention isbeing placed on the aerosol and splatter produced during dentalprocedures. This study quantifies the contamination producedby ultrasonic scalers during in vitro scaling without coolantwater. When compared with the handheld curette used as a control,all ultrasonic scalers and tips tested produced significantaerosol and splatter regardless of the type of scaler, the powerlevel or the insert. The ADA-recommended method for controllingcontaminated aerosol and splatter is the use of a large-borehigh-volume evacuator. This study supports the ADA recommendationof use of a high-volume evacuator whenever ultrasonic scalingis performed.
