Summary of research results obtained from this project carried out from 2004 to 2006 were as follows :1. Differences in the efficiency of obtaining bond strength to cervical tooth substance and the reliability in inherent bond strength of each system were recognized in typical all-in-one adhesive systems.2. In the dumbbell-form specimen obtained from human tooth for the micro-tensile bond test having a square cross-section (1.0 × 1.0mm) and 0.65mm the curvature for regulating the narrowest part and 1.0mm the length of parallel portion was effective to improve the reliability of the value of μ-TBS. In addition, the effectiveness in the beam specimen having a square cross-section (1.0 × 1.0mm) was also recognized.3. In standardized V-shaped cavity cervical composite restoration, the occlusal microleakage did not vary with the final preparation unit (an Er : YAG laser unit : L or a rotary cutting unit : R) and the adhesive system used. The gingival microleakage of L restoration was greater than that of R restoration, regardless of the system.4. The μ-TBS to the gingival dentin wall did vary with the unit used for final cavity preparation. However the μ-TBS was not influenced by the difference in systems.5. The immediate bond strength of 3 typical self-etching primer systems to enamel was similar to that of a typical self-priming adhesive system. In addition, the values of those 3 systems to dentin were similar to or greater than that of the self-priming adhesive system.6. It was difficult to specify a clear relationship between the fracture mode and the value μ-TBS.7. It could be suggested that both the formation of hybrid layer and the appearance of meshwork at the resin-dentin interface did vary with adhesive properties, i.e., decalcification ability and permeability.8. The mean μ-TBS to caries-affected dentine was significantly lower than the value to sound dentine, and it seemed difficult to anticipate the level of μ-TBS from the value of DIAGNOdent^<TM>.

2004年至2006年期间，本项目所取得的研究成果总结如下：1。在典型的一体化粘结系统中，每个系统获得与牙颈部物质的粘结强度的效率和固有粘结强度的可靠性存在差异.在1.0 × 1.0mm方形截面、0.65mm的哑铃型牙体微拉伸粘结试验中，调整最小弯曲部分的曲率和1.0mm平行部分的长度对提高μ-TBS值的可靠性是有效的。此外，在正方形截面（1.0 × 1.0mm）的梁试样中也得到了验证.在标准化的V形腔颈椎复合修复体中，咬合微渗漏并不随最终准备单元（Er：YAG激光单元：L或旋转切割单元：R）和所使用的粘合剂系统而变化。无论哪种系统，L型修复体的牙龈微渗漏均大于R型修复体.牙龈牙本质壁的μ-TBS确实随用于最终洞制备的单元而变化。而μ-TBS不受系统差异的影响. 3种典型的自酸蚀底漆系统与牙釉质的即刻粘结强度与典型的自底漆粘合剂系统的即刻粘结强度相似。另外，这3种系统对牙本质的粘附力值与自吸粘接系统相近或大于自吸粘接系统.很难确定断裂模式与μ-TBS值之间的明确关系。7.这表明，混合层的形成和树脂-牙本质界面处的网状结构的外观确实随粘合性能而变化，即，脱钙能力和渗透性。患龋牙本质的μ-TBS值显著低于健康牙本质的μ-TBS值，并且似乎难以从DIAGNOdent值预测μ-TBS的水平<TM>。
