背景自酸蚀粘合剂被认为可以防止在后路树脂基复合材料固定下使用时的术后敏感。作者测试了一个双重假设：自酸蚀或SE粘合剂比全酸蚀或TE粘合剂术后敏感性低; SE粘合剂比TE粘合剂釉质边缘完整性差。根据磨牙和前磨牙的I类和II类矫正选择患者。作者用SE材料（Clearfil SE Bond，Kuraray America，纽约）进行了30次置换，用Prime & Bond NT（Dentsply Caulk，米尔福德，特拉华州）进行了36次置换，它使用34%的磷酸同时蚀刻牙釉质和牙本质。制备物是标准设计的，所有边缘都在釉质中，没有斜切。在橡胶坝隔离后，作者用自酸蚀底漆（用于Clearfil SE Bond）或用专有的34%磷酸（用于Prime & Bond NT）蚀刻处理釉质和牙本质壁，然后应用相应的牙本质粘合剂。使用适用于后牙矫正的专有混合树脂基复合材料进行牙齿修复：Clearfil SE Bond的Clearfil AP-X或Prime & Bond NT的Esthet X Micro Matrix Restorative。在术前、术后2周、8周和6个月对修复牙进行冷敏感性、空气敏感性、咀嚼力敏感性以及边缘变色的评价。方差分析显示，在任何回忆时间，SE和TE材料之间的术后敏感性无统计学显著差异。在6个月时，所有矫正的边缘变色被评定为“不存在”。只有一颗牙齿在6个月时对咬合力敏感。SE粘合剂在敏感性和边缘变色方面与TE粘合剂没有差异。术后敏感性可能取决于修复技术，而不是使用的牙本质粘合剂的类型。
Background. Self-etching adhesives are believed to prevent postoperative sensitivity when used under posterior resin-based composite restorations. The authors tested a twofold hypothesis: a self-etch, or SE, adhesive would result in less postoperative sensitivity than a total-etch, or TE, adhesive; and SE adhesive would result in poorer enamel marginal integrity than a TE adhesive.Methods. Patients were selected on the basis of requiring Class I and II restorations in molars and premolars. The authors placed 30 restorations with the SE material (Clearfil SE Bond, Kuraray America, New York) and 36 restorations with Prime & Bond NT (Dentsply Caulk, Milford, Del.), which uses 34 percent phosphoric acid to etch enamel and dentin simultaneously. Preparations were of standard design, with all margins in enamel without beveling. Upon rubber dam isolations, the authors conditioned the enamel and dentin walls with the self-etching primer (for Clearfil SE Bond) or etched with the proprietary 34 percent phosphoric acid (for Prime & Bond NT), followed by application of the corresponding dentin adhesive. Teeth were restored with the proprietary hybrid resin-based composite indicated for posterior restorations: Clearfil AP-X for Clearfil SE Bond or Esthet X Micro Matrix Restorative for Prime & Bond NT. The restored teeth were evaluated preoperatively and at two weeks, eight weeks and six months postoperatively for sensitivity to cold (ice), air and masticatory forces, as well as for marginal discoloration.Results. Analysis of variance revealed no statistically significant differences in postoperative sensitivity between the SE and TE materials at any recall time. Marginal discoloration was rated as "absent" for all restorations at six months. Only one tooth displayed sensitivity to occlusal forces at six months.Conclusion. The SE adhesive did not differ from the TE adhesive in regard to sensitivity and marginal discoloration.Clinical Implications. Postoperative sensitivity may depend on the restorative technique rather than on the type of dentin adhesive used.
