Er-YAG激光照射可以改善牙本质的粘附性能。我们测试的假设，即牙本质粘附的影响Er-YAG激光调节。人磨牙的浅表或深层牙本质：（a）用35%H3PO4酸蚀刻;（B）用2 Hz和180 mJ的Er-YAG激光（KaVo）照射，并用水冷却;（c）激光和酸蚀刻。将Single Bond（3 M ESPE）和Z100复合材料（3 M ESPE）粘结到制备的表面。储存后，对样本进行剪切破坏测试，将粘合界面在EDTA中脱矿并进行透射电子显微镜处理。双因素方差分析显示，调理处理和治疗和牙本质深度之间的相互作用显着影响剪切粘结强度的结果。单独酸蚀产生的剪切粘结强度值显著高于单独激光消融或与酸蚀组合实现的剪切粘结强度值。Er-YAG激光产生了对牙本质粘附性产生不利影响的激光改性层，因此它不构成传统酸蚀的替代粘结策略。
Er-YAG laser irradiation has been claimed to improve the adhesive properties of dentin. We tested the hypothesis that dentin adhesion is affected by Er-YAG laser conditioning. Superficial or deep dentin from human molars was: (a) acid-etched with 35% H3PO4; (b) irradiated with an Er-YAG laser (KaVo) at 2 Hz and 180 mJ, with water-cooling; and (c) laser- and acid-etched. Single Bond (3M ESPE) and Z100 composite (3M ESPE) were bonded to the prepared surfaces. After storage, specimens were tested in shear to failure, Bonded interfaces were demineralized in EDTA and processed for transmission electron microscopy. Two-way ANOVA revealed that conditioning treatment and interaction between treatment and dentin depth significantly influenced shear bond strength results. Acid-etching alone yielded shear bond strength values that were significantly higher than those achieved with laser ablation alone, or in combination with acid-etching, The Er-YAG laser created a laser-modified layer that adversely affects adhesion to dentin, so it does not constitute an alternative bonding strategy to conventional acid etching.
