摘要
目前,铒∶钇铝石榴石(erbium∶yttrium-aluminum-garnet,Er∶YAG)激光可用于临床治疗牙体硬组织疾病,包括防龋、去腐备洞、根管预备及消毒、根尖手术等。体外实验已证实,Er∶YAG激光可促进牙本质形貌及有机物和无机物的成分改变。为进一步研究Er∶YAG激光在口腔科的适用性,一些学者利用现代生物材料分析方法对Er∶YAG激光照射前后牙本质进行分析,从牙本质的形貌、结构及成分变化,探讨Er∶YAG激光照射对牙本质的作用。文章对既往研究中涉及的研究方法及结果做一阐述,以期为后续研究设计及临床实践提供参考。
Nowadays,erbium∶yttrium-aluminum-garnet(Er∶YAG)laser has been used widely in dental hard tissue treatment,including caries prevention,caries removal,canal preparation and decontamination,periapical surgery and so on. In vitro studies have shown that Er∶YAG laser irradiation can cause chemical and morphological changes in dentin. In order to identify the adaptability of Er∶YAG laser to dental hard tissue,some researchers have utilized analysis methods of modern biological material investigations. They analyzed the dentin before and after Er∶YAG laser irradiation,contrasted the change of dentin morphology,structure and chemical composition. The aim of this paper is to review the previous research methods and results, in order to provide reference for the future study design and clinical practice.
