本研究的目的是通过使用相同的牙齿对照和不同的横截面表面积进行微拉伸粘结强度（μTBS）测试，评价和验证等离子体处理改善粘合剂/牙本质界面粘结的有效性。拔除未萌出的人第三磨牙，去除牙冠暴露牙本质表面。对于每个牙本质表面，其一半用非热氩等离子体刷处理，而另一半用载玻片屏蔽并用作未处理的对照。然后按照指示施用Adper Single Bond Plus粘合剂和Filtek Z250牙科复合材料。将制备好的牙齿进一步切割成截面尺寸为1×1 mm 2、1×2 mm 2和1×3 mm 2的微棒试样，进行μTBS测试。测试结果表明，等离子体处理的样本比其相应的相同牙齿对照提供了更强的粘合剂/牙本质粘结。与未处理的对照相比，等离子体处理使横截面积为1×1 mm 2和1×2 mm 2的试样的粘结强度在统计学上显著更高，平均增加分别为30.8%和45.1%。使用光学和电子显微镜的界面检查证实，等离子体处理通过减少缺陷/空隙和增加牙本质小管中的树脂标签长度来改善粘合剂/牙本质界面的质量。
The objective of this study is to evaluate and verify the effectiveness of plasma treatment for improving adhesive/dentin interfacial bonding by performing micro-tensile bond strength (μTBS) test using the same-tooth controls and varying cross-sectional surface areas. Extracted unerupted human third molars were used by removing the crowns to expose the dentin surface. For each dentin surface, one half of it was treated with a non-thermal argon plasma brush, while another half was shielded with glass slide and used as untreated control. Adper Single Bond Plus adhesive and Filtek Z250 dental composite were then applied as directed. The teeth thus prepared were further cut into micro-bar specimens with cross-sectional size of 1×1 mm2, 1×2 mm2 and 1×3 mm2 for μTBS test. The test results showed that plasma treated specimens gave substantially stronger adhesive/dentin bonding than their corresponding same tooth controls. As compared with their untreated controls, plasma treatment gave statistically significant higher bonding strength for specimens having cross-sectional area of 1×1 mm2 and 1×2 mm2, with mean increases of 30.8% and 45.1%, respectively. Interface examination using optical and electron microscopy verified that plasma treatment improved the quality of the adhesive/dentin interface by reducing defects/voids and increasing the resin tag length in dentin tubules.
