With the introduction of the Er:YAG laser, it has become possible to remove enamel and dentin more effectively and efficiently than with other lasers. Thermal damage is reduced, especially in conjunction with water spray. Since FDA (Federal Drug Administration) approval of the Er:YAG laser in 1997--for caries removal, cavity preparation and conditioning of tooth substance - there have been many reports on the use of this technique in combination with composite resins. Moreover, cavity pretreatment with Er:YAG laser (laser etching) has been proposed as an alternative to acid etching of enamel and dentin. Reports evaluating the adhesion of glass-ionomer cements to Er:YAG-lased tooth substance are scarce. This article reviews the literature regarding adhesion and sealing efficacy using different (pre)treatment protocols in association with Er:YAG laser preparation. Recent research has shown that lasing of enamel and dentin may result in surface and subsurface alterations that have negative effects on both adhesion and seal. It is concluded that at present, it is advisable to respect the conventional pretreatment procedures as needed for the respective adhesive materials. Although the majority of present day reports show that microleakage and bond strength are negatively influenced by laser (pre)treatment (compared with conventional preparation), there is ongoing discussion of how adhesion is best achieved on Er:YAG-lased surfaces.
随着铒激光的问世，与其他激光相比，它可以更有效地去除牙釉质和牙本质。热损伤减少，尤其是与水喷雾结合使用时。自 1997 年 FDA（美国食品和药物管理局）批准铒激光用于龋齿去除、窝洞预备和牙本质预处理以来，已有许多关于将该技术与复合树脂联合使用的报道。此外，还提出了用铒激光（激光蚀刻）预处理窝洞作为牙釉质和牙本质酸蚀刻的替代方法。评价玻璃离子水门汀与铒激光处理牙体之间黏附力的报道很少。本文回顾了不同（预处理）方案联合铒激光预备时，使用不同（预处理）方案对黏附力和密封效果的文献。最近的研究表明，牙釉质和牙本质的激光照射可能导致表面和次表面改变，对黏附力和密封都有负面影响。因此，目前的建议是根据各自的黏附材料，必要时仍需遵循传统的预处理程序。尽管目前大多数报道显示，与传统预备相比，激光（预处理）会对微渗漏和黏结强度产生负面影响，但仍在讨论如何在铒激光处理后的表面上实现最佳黏附。
