Summary of research results obtained from a project titled "Examination in Adhesion to Clinical Restorable Tooth Surface using An In-vivo/vitro Bi-use Portable Adhesion Tester" carried out from 1999 to 2001 was as follows :1. Improvements, i.e., (1) transparent guide tip for bonded surface, (2) connector for testing wire, (3) the driving gear of the tester, for an in-vivo/vitro bi-use portable adhesion tester developed in 1997 by the investigators of this project were successful for fast operation and the accuracy of the measurement.2. The tensile bond strengths of typical resin adhesive systems to the exposed dentin of cervical abrasion lesion (CD) were 10.5〜15.8 MPa in vivo and 11.2〜16.1 MPa in vitro. The in vivo value was similar to or smaller than the in vitro value. The bond strength to CD was 10〜13 % smaller than the value of cervical sound dentin (SD).3. In vitro bond strengths of typical light cured glass ionomer restorative system (LGI) / compomer restorative systems were 8.4 / 5.9〜9.5 MPa. The bond strength of the compomer systems took a middle position between LGI and the light cured composite restorative system.4. The bond strengths of typical resin adhesive systems, Single Bond / Clearfil Mega Bond / Fluoro Bond / AQ Bond / One-Up Bond F, were 26.5 / 21.6 / 13.7 / 13.5 / 10.6 MPa to sound enamel and 17.7 / 25.0 / 13.7 / 18.7 / 11.2 MPa to SD.5. In vitro bond strengths of resin adhesive systems to CD / SD were 16.0〜22.5 / 18.9〜25.0 MPa, and the CD value was 10〜15 % smaller than the SD value.6. Conforcal Laser Scanning Microscope was an effective apparatus in addition to SEM for the observation and the quantitative measurement at the resin-dentin interface.

1999 - 2001年项目“体内/体外两用便携式黏附仪检测临床可修复牙面黏附”的研究结果总结如下：该项目的研究人员于1997年研制了一种体内/体外两用便携式附着力测试仪，改进了(1)粘接表面的透明导尖，(2)测试导线的连接器，(3)测试仪的驱动齿轮，成功地提高了操作速度和测量精度。典型树脂胶粘剂体系与颈磨蚀病变外露牙本质的体内抗张强度为10.5 ~ 15.8 MPa，体外抗张强度为11.2 ~ 16.1 MPa。体内值与体外值相近或小于体外值。与CD的结合强度比颈声牙本质（SD）小10 ~ 13%。典型光固化玻璃离子修复体系(LGI) /复合修复体系的体外结合强度为8.4 / 5.9 ~ 9.5 MPa。复合材料体系的结合强度介于LGI和光固化复合材料修复体系之间。典型树脂粘接体系Single bond / Clearfil Mega bond / Fluoro bond / AQ bond / One-Up bond F对sound牙釉质的粘接强度为26.5 / 21.6 / 13.7 / 13.5 / 10.6 MPa，对SD.5的粘接强度为17.7 / 25.0 / 13.7 / 18.7 / 11.2 MPa。树脂胶粘剂体系对CD / SD的体外结合强度为16.0 ~ 22.5 MPa / 18.9 ~ 25.0 MPa， CD值比SD值小10 ~ 15%。激光共焦扫描显微镜是除扫描电镜外，对树脂-牙本质界面进行观察和定量测量的有效仪器。
