牙釉质和牙本质样本暴露于口外脉冲钕钇铝石榴石（Nd：YAG）激光。使用扫描电子显微镜和组织学技术观察激光照射的样品，以确定激光的效果。本研究提供了以下几点：（1）在适当的处理下，釉质可以被激光蚀刻到与磷酸蚀刻相当的深度;（2）龋性和非龋性牙本质都可以被Nd：YAG激光汽化。在组织学上或在SEM下未观察到任何牙釉质或牙本质样品的开裂或碎裂。
Enamel and dentin samples were exposed extraorally to a pulsed neodymium yttriuma1uminumgarnet (Nd:YAG) laser. The lased samples were observed using both scanning electron microscopy and histological techniques to determine the effects of the laser. The present study has provided the following points: (1) Properly treated, enamel can be 1aser etched to a depth comparable to that achieved with phosphoric acid etching; and (2) both carious and noncarious dentin can be vaporized by the Nd:YAG laser. No cracking or chipping of any enamel or dentin sample was observed histologically or under the SEM.
