实验比较了甘油磷酸二甲基丙烯酸酯（GPDM）基两步法自酸蚀（SE）胶粘剂和10-甲基丙烯酰氧基癸基磷酸二氢酯（MDP）基通用胶粘剂在不同牙釉质粘接应用模式下的粘接性能。测定了粘接剂与牙釉质粘接的微拉伸强度（μTBS）。测试了基于GPDM的两瓶两步自蚀刻粘合剂（Optibond Versa，OV）和三种单瓶基于MDP的通用粘合剂，一种自蚀刻（Tetric N Bond Universal，TNBU），两种具有蚀刻和冲洗（E&R）处理（Single Bond Universal（SBU）; Clearfil Universal Bond Quick（CUBQ））。扫描电子显微镜（SEM）评价在粘接界面的纳米泄漏。牙釉质表面粗糙度测定仪测定后，磷酸蚀刻，OV底漆，或TNBU条件。SEM观察了相应的表面形貌。核磁共振和X射线光电子能谱（XPS）的特点与粘合剂条件下的羟基磷灰石（HAPS）的化学键合。无论老化与否，蚀刻和冲洗样品的结合都明显强于自蚀刻样品（p < 0.05）。初发和老年期OV的μTBS值均显著高于TNBU（p < 0.05）。除TNBU外，老化未显著降低任何样品的μTBS（p < 0.05），但其显著加重了纳米渗漏。蚀刻和冲洗处理导致比自蚀刻更少的纳米泄漏; OV样品在老化之前和之后的泄漏都小于TNBU。磷酸酸蚀达到最高的釉质表面粗糙度，其次是OV底漆。用NMR证实了经TNBU、SBU和CUBQ处理的羟基磷灰石中的Ca-O-P键，其结果与经处理的羟基磷灰石粉末的XPS观察结果相似，但OV引物除外。基于GPDM的两步自蚀刻粘合剂可以在自蚀刻模式下提供比基于MDP的通用粘合剂更高的微机械保持潜力、粘结强度和耐久性，但在蚀刻和冲洗模式下提供比基于MDP的通用粘合剂更低的性能。测试的粘合剂都不能避免老化后的纳米泄漏。
The bonding performance of a glycerol phosphate dimethacrylate (GPDM)-based, two-step, self-etch (SE) adhesive was experimentally compared to that of 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-based universal adhesives in different application modes for enamel bonding. Microtensile bond strength (μTBS) for adhesives bonded to enamel was measured initially (24 h water storage) and after 10 000 thermocycles plus water storage for 30 days. A GPDM-based, two-bottle, two-step, self-etch adhesive (Optibond Versa, OV) and three one-bottle MDP-based universal adhesives, one self-etching (Tetric N Bond Universal, TNBU) and two with etch-and-rinse (E&R) processing (Single Bond Universal (SBU); Clearfil Universal Bond Quick (CUBQ)), were tested. Scanning electron microscopy (SEM) evaluated nanoleakage at the bonding interfaces. A profilometer determined roughnesses of enamel surfaces after phosphoric acid etching, OV priming, or TNBU conditioning. SEM observed the corresponding surface morphology. NMR and X-ray photoelectron spectroscopy (XPS) characterized chemical bonding in hydroxyapatites (HAps) conditioned with the adhesives. Etch-and-rinse samples had significantly stronger bonding than self-etch samples (p < 0.05) irrespective of aging. The μTBS values for initial and aged OV were significantly higher than those of TNBU (p < 0.05). Aging did not significantly decrease μTBS for any sample except TNBU (p < 0.05), but it significantly aggravated nanoleakage. Etch-and-rinse processing resulted in less nanoleakage than self-etching; the OV samples leaked less than TNBU, both before and after aging. Phosphoric acid etching achieved the highest enamel surface roughness, followed by OV primer. Ca–O–P bonds in hydroxyapatite conditioned with TNBU, SBU, and CUBQ were confirmed by NMR, which showed similar results to XPS observations of conditioned hydroxyapatite powders except OV primer. The GPDM-based, two-step, self-etch adhesive can provide higher micromechanical retention potential, bond strength, and durability than the MDP-based universal adhesive in self-etch mode but lower performance than the MDP-based universal adhesive in etch-and-rinse mode. None of the tested adhesives could avoid nanoleakage after aging.
