The purpose of this study was to examine the bond strength of AH26 to human coronal dentin exposed to DMSO. A total of 70 dentin specimens were equally divided into two groups. Each dentin surface was pre-treated with 2 mL of 2.5% NaOCl, 3 mL of EDTA 17%, and distilled water. One group was finally rinsed with 50% DMSO. Following the AH26 application, the bond strength was tested by subjecting the samples to a shear load at a crosshead speed of 0.5 mm/min using universal testing equipment. The results according to paired samples -test indicated that there was a statistically insignificant difference between the two groups. Therefore, DMSO had no effect on the bond strength of AH26 root sealer to dentin.
本研究的目的是检测AH26与暴露于二甲基亚砜（DMSO）的人冠部牙本质之间的粘结强度。总共70个牙本质标本被平均分为两组。每个牙本质表面先用2 mL 2.5%的次氯酸钠、3 mL 17%的乙二胺四乙酸（EDTA）和蒸馏水进行预处理。一组最后用50%的DMSO冲洗。应用AH26后，使用万能测试设备以0.5 mm/min的十字头速度对样品施加剪切载荷来测试粘结强度。根据配对样本检验的结果表明，两组之间在统计学上没有显著差异。因此，DMSO对AH26根充糊剂与牙本质的粘结强度没有影响。
