本研究评价了在37℃下不同时间的水老化后，光聚合、再矿化无定形磷酸钙聚合物复合粘接系统与牙本质的粘结强度和相关性能。实验用无定形磷酸钙基材和衬里复合材料由光活化树脂制成，该树脂由2，2-bis[p-(2’-hydroxy-3’-methacryloxypropoxy)phenyl]propane、甲基丙烯酸三乙二醇酯、甲基丙烯酸羟乙酯和二甲基丙烯酸锆酯组成。由乙氧基化双酚A二甲基丙烯酸酯(EBPADMA)、TEGDMA、HEMA和邻苯二甲酸甲基丙烯酰氧乙酯(MEP)组成的光活化树脂制成了一种实验性的正畸复合材料，命名为ETHM。在这两个复合材料系列中，比较了三种填料：1)新鲜沉淀的锆改性ACP，2)球磨的Zr-ACP，3)可离子浸出的氟化物玻璃。除了剪切粘结强度(SBS)外，还确定了正畸复合材料的断裂功和破坏模式。基层和衬里ACP复合材料的SBS不受填料类型和浸泡时间的影响。在正畸ACP复合材料系列中，球磨ACP复合材料显示出比制备的ACP复合材料更高的力学优势，并产生与更强的粘结相一致的更高的失效模式。在6个月的水溶液暴露后，80%的样本在牙本质-底漆界面失败，总体粘结强度降低42%。BTHZ和ETHM基ACP复合体是一种潜在的有效的抗脱矿再矿化剂，分别作为正畸粘固剂和保护性衬里具有临床应用价值。对粘结强度和破坏形式的分析表明，研磨的ACP复合材料可能在临床应用中提供更大的潜力。
This study evaluates the bond strength and related properties of photo-polymerizable, remineralizing amorphous calcium phosphate (ACP) polymeric composite-adhesive systems to dentin after various periods of aqueous aging at 37 °C. An experimental ACP base and lining composite was made from a photo-activated resin comprising 2,2-bis[p-(2’-hydroxy-3’-methacryloxypropoxy)phenyl]propane (Bis-GMA), triethylene glycol dimethacrylate (TEGDMA), 2-hydroxyethyl methacrylate (HEMA) and zirconyl dimethacrylate (ZrDMA); designated BTHZ. An experimental orthodontic composite was formulated from a photo-activated resin comprising ethoxylated bisphenol A dimethacrylate (EBPADMA), TEGDMA, HEMA and methacryloxyethyl phthalate (MEP); designated ETHM. In both composite series three fillers were compared: 1) freshly precipitated zirconium-modified ACP freshly precipitated (as-prepared Zr-ACP), 2) milled Zr-ACP and 3) an ion-leachable fluoride glass. In addition to the shear bond strength (SBS), work to fracture and failure modes of the orthodontic composites were determined. The SBS of the base and lining ACP composites appeared unaffected by filler type or immersion time. In the orthodontic ACP composite series, milled ACP composites showed initial mechanical advantages over as-prepared ACP composites, and produced higher incidence of a failure mode consistent with stronger adhesion. After six months of aqueous exposure, 80 % of specimens failed at the dentin-primer interface, with a 42 % overall reduction in bond strength. BTHZ and ETHM based ACP composites are potentially effective anti-demineralizing-remineralizing agents with possible clinical utility as protective base-liners and orthodontic cements, respectively. The analysis of the bond strength and failure modalities suggests that milled ACP composites may offer greater potential in clinical applications.
