Abstract

Ultrasonic dental scalers produce substantial aerosol and splatter, which may contain blood and other potential hazards to dental personnel. Ultrasonic scalers use high-frequency vibration to remove tartar from teeth. Dentists compared several ultrasonic scalers with conventional hand scaling on tooth models. Hand scaling produced virtually no fine aerosols or liquid splatter, but ultrasonic scaling produced aerosol clouds and splatter as far as 26 cm from the instrument tip. High-volume suction evacuators may reduce the risk to dental staff from aerosolized blood and saliva.
