As concern about indoor air quality increases, attention is being placed on the aerosol and splatter produced during dental procedures. This study quantifies the contamination produced by ultrasonic scalers during in vitro scaling without coolant water. When compared with the handheld curette used as a control, all ultrasonic scalers and tips tested produced significant aerosol and splatter regardless of the type of scaler, the power level or the insert. The ADA-recommended method for controlling contaminated aerosol and splatter is the use of a large-bore high-volume evacuator. This study supports the ADA recommendation of use of a high-volume evacuator whenever ultrasonic scaling is performed.
随着人们对室内空气质量的关注度不断提高，牙科手术过程中产生的气溶胶和飞沫受到了更多关注。本研究对无冷却用水情况下超声洁牙机在体外洁牙过程中产生的污染物进行了量化。与用作对照的手持刮治器相比，所有测试的超声洁牙机及其刀头，无论洁牙机类型、功率水平或刀头如何，都会产生大量的气溶胶和飞沫。美国牙科协会（ADA）推荐的控制受污染气溶胶和飞沫的方法是使用大口径高流量吸引器。本研究支持ADA关于在进行超声洁牙时使用高流量吸引器的建议。
