Over time teeth are exposed to several physical-chemical alterations, which may change the dental structure. Therefore, dental clinicians must be aware of how to manage the altered tissue. Laser irradiation and self-etch adhesives may be an option in this situation. This study aimed to evaluate the bond strength of self-etch adhesive systems associated with different treatments on hypermineralized dentin. 80 bovine incisors were distributed into two groups: Universal (3M ESPE; n = 40) and Optibond All in One (Kerr; n = 40). Five treatments were performed for each group (n = 8): (T1) adhesive system (control); (T2) acid + adhesive; (T3) Er,Cr:YSGG laser + adhesive; (T4) acid + Er,Cr:YSGG laser + adhesive; (T5) Er,Cr:YSGG laser + acid + adhesive. After bond and restorative procedures, teeth were submitted to microshear bond strength test. ANOVA two-way followed by Games-Howell Test was performed. Statistical significance difference was observed for adhesive systems and treatments ...

Er，Cr：YSGG激光辐照和自蚀刻胶粘剂体系对高矿化牙本质的影响：粘结强度评估

随着时间的流逝，牙齿暴露于几种物理化学变化中，这可能会改变牙齿的结构。因此，牙科临床医生必须知道如何处理改变的组织。在这种情况下，可以选择激光照射和自蚀刻粘合剂。这项研究旨在评估在高矿化牙本质上进行不同处理的自蚀刻胶粘剂系统的粘结强度。将80个牛切牙分为两组：Universal（3M ESPE； n = 40）和Optibond All in One（Kerr； n = 40）。每组（n = 8）进行五种治疗：（T1）粘合剂系统（对照）；（T2）酸+胶; （T3）Er，Cr：YSGG激光+粘合剂; （T4）酸+ Er，Cr：YSGG激光+粘合剂; （T5）Er，Cr：YSGG激光+酸+粘合剂。经过粘结和修复程序后，牙齿经受了微剪切粘结强度测试。进行ANOVA双向，然后进行Games-Howell测试。对于粘合剂体系和处理，观察到统计学显着性差异。
