摘　要：掺铒钇铝石榴石（Er:YAG）是一种短脉冲型的激光，可用于硬组织消融、软组织切割及根管荡洗等，在乳牙去腐、树脂粘接、多生牙拔除、舌系带延长、根管荡洗等方面具有重要意义。由于Er:YAG激光在许多应用范围可以替代涡轮手机，减少了振动和气溶胶的产生，微创无痛操作更为患儿接受，因此，在儿童口腔医学中的应用研究越来越广泛。本文将从上述方面对Er:YAG激光在儿童口腔医学中的应用进展进行综述，为进一步的临床应用提供参考。

Abstract: The erbium-trium aluminum garnet (Er:YAG) is a short-pulse laser that can be used for hard tissue ablation, soft tissue debridement and root canal decontamination. It can be effectively used in deciduous teeth removal, resin bonding, superordinate teeth extraction, lingual lacunae extension, root canal washing and other aspects. Because the operation is painless, it is more acceptable to children, hence it is very common in pediatric stomatology application research. This article reviews the application of Er:YAG in pediatric stomatology from the above aspects.
Key words: Er:YAG; laser; gingivectomy; photoninduced photoacoustic streaming; pediatric stomatology
