背景资料：本研究的目的是评估化学机械龋去除和传统的龋齿挖掘的影响，对三种不同的牙本质粘合剂system.Methods的微拉伸粘结强度：30个提取的人下颌磨牙的龋齿的放射线标志延伸到牙本质的中间三分之一，纵向通过在颊舌方向的龋损的中心，产生两个部分。每颗牙齿的一半用碳化钨钻挖，另一半用Carisolv（R）进行化学机械处理。三种牙本质粘结系统：施加蚀刻和冲洗单瓶粘合剂（SingleBond，3 MESPE）;两瓶两步自蚀刻粘合系统（OneCoatSelfEtchingBond，ColtenWhaledent）;和单步单瓶自蚀刻粘合剂（AdperEasyBond Self-EtchAdhesive，3 MESPE），并进行复合材料构建。测试试样的微拉伸粘结强度。数据进行了分析，使用双向方差分析和成对多重比较进行了使用Holm-Sidak方法。结果：蚀刻和冲洗粘合剂和两瓶自蚀刻系统表现出显着较高的粘结强度比单瓶自蚀刻系统。结论：Carisolv（R）不影响不同粘结剂体系对龋损牙本质的微拉伸粘结强度。
Background: The aim of this study was to evaluate the influence of chemomechanical caries removal and conventional caries excavation on the microtensile bond strength of three different dentine adhesive systems.Methods: Thirty extracted human mandibular molars with radiographic signs of dental caries extending up to the middle third of dentine were sectioned longitudinally through the centre of the carious lesion in a buccolingual direction to yield two sections. One half of each tooth was excavated by tungsten carbide bur and the other half was chemomechanically treated with Carisolv (R). Three dentine bonding systems: an etch-and-rinse single bottle adhesive (Single Bond, 3M ESPE); a two bottle, two-step self-etch bonding system (One Coat Self Etching Bond, Coltene Whaledent); and a single-step, single bottle self-etch adhesive (Adper Easy Bond Self-Etch Adhesive, 3M ESPE) were applied and composite build-up was done. The specimens were tested for microtensile bond strength. Data were analysed using two-way analysis of variance and pair-wise multiple comparisons were done using the Holm-Sidak method.Results: The etch-and-rinse adhesive and two bottle self-etch system showed significantly higher bond strength than the single bottle self-etch system. Caries excavation method had no influence on bond strength values.Conclusions: Carisolv (R) did not affect the microtensile bond strength values of different adhesive systems tested to the caries affected dentine.
