使用体外系统测定了磨光NaF、高岭土或甘油单独或在不同组合中对牙本质渗透性的影响。结果表明，重要的变量不是浆料的任何成分，而是抛光过程本身。磨光牙本质会在牙本质表面形成部分涂抹层，从而充分堵塞牙本质小管的开口，从而减少液体通过牙本质的50%至80%。
The effects on dentin permeability of burnishing NaF, kaolin, or glycerin, alone and in various combinations, were determined using an in vitro system. The results indicate that the important variable was not any of the constituents of the paste but the burnishing process itself. Burnishing dentin creates a partial smear layer on the dentin surface, thereby occluding the orifices of dentinal tubules sufficiently to reduce fluid movement across dentin 50 to 80%.
