激光预处理牙本质对树脂粘结性能影响的研究进展

摘要

近年来，为提高牙本质与树脂的粘结性能，国内外学者围绕牙本质表面处理进行了大量的研究。激光技术的快速发展为牙本质的表面处理提供了新思路。该文从树脂水门汀的分类和特点、激光预处理原理、常用激光的种类和特点、激光预处理对牙本质表面形态的影响和对树脂粘结性能的影响五个方面作一简要综述。%In recent years,to improve the bonding performance of dentin and the resin cements,the domestic and international schol-ars have carried out extensive researches in regard to the dentin surface treatment.The rapid development of laser technology provides a new way to dentin surface preparation.The paper has made a review from the flowing five aspects:the classification and characteristics of resin cement,laser pretreatment principle,types and characteristics of commonly used laser,the influence of laser pretreatment on dentin surface morphology and the effect on the properties of resin cement.
