1. Bond strength to affected dentinIt was revealed that bond strengths of some resin bonding systems to several types of dentin surfaces affected by cervical abrasion, caries and laser irradiation showed lower bonds than those of normal dentin.2. Dynamic 3-D analysis of etched dentin surfacesTopography of wet and dried etched dentin surface was observed under a laser scanning microscope. Dentin surface etched with phosphoric acid showed shrinkage after air drying. The method that prevents shrinkage of etched collagen is ideal for sufficient penetration into demineralized dentin layer.3. Re-evaluation for the bonding performance to enamelIt was indicated that etching depth of phosphoric acid was 40 times greater than that of self etching primer. Thus, it was suggested that multiple application of self etching primer in the clinical situation. And, it was confirmed that the bond strengths to intact enamel surfaces were lower than those to ground enamel surfaces.4. SEM observation of bond … More ing interfacesThere was no correlation between the thickness of the hybrid layer and tensile bond strength. It can be considered that the mechanical properties of hybrid layer is more accessible to bond strength than its thickness.5. Clinical factors influencing dentin bondingIt was demonstrated that clinical factors (e.g. temperature, humidity, residues of temporary filling materials and endodontic treatment) influence the bond strengths of adhesive resin systems and resin luting cements to dentin.6. Bonding performance of composite resin inlaysThe bond strength of resin composite inlay to dentin was lower than that of resin composite for direct restoration. However, the bond strength indicated higher value when resin coating method was used.Consequently, it was proved that the properties of hybrid layer and bond strength varied because of the difference of composition and structure of dentin and several clinical factors. More research will be needed to confirm the optimal restorative procedures. Less

1.对牙本质的粘接强度研究结果表明，某些树脂粘接系统对牙本质表面的粘接强度在牙颈部磨损、龋蚀和激光照射后均低于正常牙本质.酸蚀牙本质表面的动态三维分析在激光扫描显微镜下观察湿、干酸蚀牙本质表面的形貌。磷酸酸蚀牙本质表面风干后收缩。防止蚀刻胶原收缩的方法是充分渗透到脱矿牙本质层的理想方法。对自酸蚀底漆与搪瓷粘接性能的再评价结果表明，磷酸的酸蚀深度是自酸蚀底漆的40倍以上。因此，建议在临床上多次使用自酸蚀底漆。并且，证实了与完整釉质表面的粘结强度低于与研磨釉质表面的粘结强度。粘结的SEM观察 ...更多信息 杂化层的厚度与拉伸粘结强度之间没有相关性。可以认为混杂层的力学性能比其厚度更容易影响粘结强度.影响牙本质粘结的临床因素研究表明，临床因素（如温度、湿度、临时充填材料的残留和根管治疗）影响树脂粘结剂和树脂粘接剂与牙本质的粘结强度.复合树脂嵌体与牙本质的粘结性能复合树脂嵌体与牙本质的粘结强度低于直接修复的复合树脂嵌体。结果表明，由于牙本质的组成和结构的不同以及临床因素的影响，混合层的性能和粘结强度也不同。需要更多的研究来确认最佳的修复程序。少
