本研究旨在通过结合疲劳测试和长期水储存来确定功能单体10-甲基丙烯酰氧基癸基磷酸二氢酯（MDP）对单步自酸蚀粘合剂的牙釉质粘结耐久性的影响。使用了含MDP的自蚀刻粘合剂Clearfil Bond SE ONE（SE）和实验粘合剂MDP free（MF）（除MDP外，其成分与SE相同）。剪切粘结强度（SBS）和剪切疲劳强度（SFS）在有或没有磷酸预蚀刻的情况下进行测量。将标本在蒸馏水中储存24 h、6个月或1年。尽管预蚀刻SE和MF在蒸馏水中储存24 h后获得的SBS和SFS值相似，但预蚀刻SE在水中储存6个月或1年后的SBS和SFS值高于MF。无论预蚀刻程序如何，SE在蒸馏水中储存6个月后的SBS和SFS值均高于24 h或1年后的值。总之，MDP可能在提高粘结强度和长期蓄水后反复亚临界荷载下的粘结耐久性方面发挥重要作用。
The present study aimed to determine the effect of the functional monomer, 10‐methacryloxydecyl dihydrogen phosphate (MDP), on the enamel bond durability of single‐step self‐etch adhesives through integrating fatigue testing and long‐term water storage. An MDP‐containing self‐etch adhesive, Clearfil Bond SE ONE (SE), and an experimental adhesive, MDP‐free (MF), which comprised the same ingredients as SE apart from MDP, were used. Shear bond strength (SBS) and shear fatigue strength (SFS) were measured with or without phosphoric acid pre‐etching. The specimens were stored in distilled water for 24 h, 6 months, or 1 yr. Although similar SBS and SFS values were obtained for SE with pre‐etching and for MF after 24 h of storage in distilled water, SE with pre‐etching showed higher SBS and SFS values than MF after storage in water for 6 months or 1 yr. Regardless of the pre‐etching procedure, SE showed higher SBS and SFS values after 6 months of storage in distilled water than after 24 h or 1 yr. To conclude, MDP might play an important role in enhancing not only bond strength but also bond durability with respect to repeated subcritical loading after long‐term water storage.
