Er,Cr:YSGG激光对乳牙硬组织粘接性能影响的研究进展

Er,Cr:YSGG激光以其能够安全、精确地切割牙体硬组织而成为近年来激光牙科学的研究热点.Er,Cr:YSGG激光照射后牙体硬组织的表面形态、成分及结构均发生改变,这些变化对后续修复材料粘接力的影响目前还存在争议.本文从Er,Cr:YSGG激光用于牙体硬组织切割的机制、乳牙组织的结构特点、Er,Cr:YSGG激光处理对乳牙牙体硬组织粘接力的影响、Er,Cr:YSGG激光在儿童口腔领域应用的安全性、优势及展望做一综述.

Research progress on the bonding strength of primary teeth after Er,Cr: YSGG laser irradiation

With many advantages such as safety, effective cutting of enamel and dentin, Er, Cr: YSGG laser has gained more and more attention in recent years. After irradiation, the morphology, composition, and structure of tooth surface has changed, yet, the effect of these alterations to the bonding strength of the subsequent material is controver-sial. The paper has made a review from the following four aspects:Mechanism for tooth hard tissue cutting with Er, Cr:YSGG laser; The structure characteristics of primary teeth; The enamel bonding strength of primary teeth after Er, Cr:YSGG laser treatment;Safety, superiority and expectation for the application of Er, Cr:YSGG laser in primary teeth.
