Air-powder abrasive systems are used in dentistry to remove dental plaque, calculus and stain from the surfaces of teeth. A model system consisting of a thin layer (14 micron) of vacuum-deposited aluminium was used to demonstrate the effectiveness of such a system. Photomicrographic analysis showed two distinct areas of removal: an inner area where removal of aluminium was complete, surrounded by an area where removal was incomplete. With the aid of a relocation pin attached to the nozzle of the instrument it was demonstrated that nozzle-target distance, the air pressure input, the flow of water and the time of operation were all factors which affected the clinical efficiency of the instrument.
气粉磨蚀系统用于牙科，以去除牙齿表面的牙菌斑、牙结石和污渍。使用一个由真空沉积铝的薄层（14微米）组成的模型系统来证明这种系统的有效性。显微照片分析显示出两个不同的去除区域：一个内部区域，铝的去除是完全的，周围是一个去除不完全的区域。借助于连接到仪器喷嘴的定位销，证明了喷嘴与目标的距离、空气压力输入、水流和操作时间都是影响仪器临床效率的因素。
