目的：本体外研究的目的是比较在热循环 (TC) 前后，有或没有额外磷酸酸蚀的情况下，不同通用粘合剂对牙釉质和牙本质的剪切粘合强度。 材料和方法：将牙齿的近中、远中、舌侧和颊面磨平，露出两个牙釉质区域和两个牙本质区域。样本被随机分为 36 组 (n = 10)。测试了四种粘合剂：Scotchbond Universal (SBU)、Prime & Bond Elect (PBE)、All-Bond Universal (ABU) 和 iBond Universal (IBU)。该应用以自蚀刻模式（SE）或蚀刻和冲洗模式（ER）进行。 Optibond FL (OFL) 用作蚀刻和冲洗对照。完成复合材料构建后，一半组在 TC 之前进行测试，另一半在 TC 之后进行测试。使用光学显微镜评估失效模式。结果：在牙釉质中，TC 之前 SE 模式的平均粘合强度范围为 13.4 至 21.9 MPa。当用作ER粘合剂时，平均粘合强度超过30 MPa。 TC 不影响任一应用模式下的平均粘合强度。关于牙本质，SE 模式的显着差异取决于粘合剂。仅在 TC 之前检测到 SBU 和 IBU 之间的差异，而在 TC 后不存在差异。当使用SBU、PBE和ABU作为ER粘合剂时，在TC之前没有检测到差异。与其他粘合剂相比，TC 仅影响 IBU。结论：通用粘合剂受益于磷酸蚀刻，因为粘合强度增加，尤其是在釉质表面。
Purpose: The purpose of this in vitro study was to compare the shear bond strength of different universal adhesives to enamel and dentin with and without additional phosphoric acid etching before and after thermocycling (TC).Materials and Methods: The mesial, distal, lingual, and buccal surfaces of the teeth were ground flat to expose two enamel areas and two dentin areas. Specimens were randomly divided into 36 groups (n = 10). Four adhesives were tested: Scotchbond Universal (SBU), Prime & Bond Elect (PBE), All-Bond Universal (ABU), and iBond Universal (IBU). The application was performed in the self-etch mode (SE) or in the etch-and-rinse mode (ER). Optibond FL (OFL) was used as an etch-and-rinse control. After composite buildups were made, half of the groups were tested before and the other half after TC. The failure mode was evaluated using a light microscope.Results: In enamel, mean bond strengths ranged from 13.4 to 21.9 MPa in the SE mode before TC. When used as an ER adhesive, mean bond strengths exceeded 30 MPa. TC did not influence the mean bond strengths in either application mode. Regarding dentin, significant differences in the SE mode were adhesive dependent. Differences were only detected between SBU and IBU before TC and were not present after TC. When SBU, PBE, and ABU were used as ER adhesives, no differences were detected before TC. TC only affected IBU when compared to the other adhesives.Conclusion: Universal adhesives benefit from phosphoric acid etching, as bond strengths increased especially at enamel surfaces.
