摘要：

背景：虽然聚氨酯黏结剂具有的较强的黏结力，但其黏结条件不符合应用于口腔黏结剂的基本条件。
目的：观察催化剂对聚氨酯黏结剂黏结性能的影响。
方法：选择20颗无龋坏青年人前磨牙或前牙制备牙釉质黏结面，铸造40个直径3 mm、高3 mm的圆柱状瓷块，分组黏固，每组5颗离体牙，10个瓷块：辛酸亚锡黏结剂组(以聚氨酯黏结剂与辛酸亚锡联合黏固)、五甲基二乙烯三胺黏结剂组(以聚氨酯黏结剂与五甲基二乙烯三胺联合黏固)、单纯聚氨酯黏结剂组、帕娜碧亚黏结剂组。
结果与结论：辛酸亚锡黏结剂组黏结强度最大，五甲基二乙烯三胺黏结剂组和单纯聚氨酯黏结剂组次之，帕娜碧亚黏结剂组最小。辛酸亚锡黏结剂组、五甲基二乙烯三胺黏结剂组、单纯聚氨酯黏结剂组黏结强度均高于帕娜碧亚黏结剂组(P < 0.05)，且辛酸亚锡与五甲基二乙烯三胺的加入缩短了黏结剂凝固时间。说明催化剂可有效缩短聚氨酯黏结剂的凝固时间，提高聚氨酯黏结剂的黏结强度。

Abstract:

BACKGROUND: Although polyurethane binder has a strong cohesive force, the cohre conditions do not comply with the basic conditions used in oral adhesive.
OBJECTIVE: To observe the effect of catalyst on the performance of polyurethane binder.
METHODS: Freshly extracted 20 non-carious human premolars or anterior teeth were collected to prepare flat mesial and distal enamel bonding interface with diamond bur. Totally 40 ceramic discs (3 mm in diameter, 3 mm in height) were fabricated, and then cemented on enamel bonding interface. These teeth and ceramic discs were evenly divided into four groups: stannous octoate binder group (polyurethane binder+stannous octoate), pentamethyldie thylenetriamine group (polyurethane binder+pentamethyldie thylenetriamine), the pure polyurethane binder group and Panaviya F adhesive group.
RESULTS AND CONCLUSION: Adhesive strength of the stannous octoate binder group was the biggest, and that of the pentamethyldie thylenetriamine and pure polyurethane binder groups were smaller, while that of the Panaviya F adhesive group was the minimum. Adhesive strength of stannous octoate binder group, pentamethyldie thylenetriamine group and pure polyurethane binder group were all higher than that of the Panaviya F adhesive group (P < 0.05). Besides, the addition of stannous octoate and pentamethyldie thylenetriamine group shortened the solidification time. These findings suggest that catalyst can effectively shorten the solidification time of the polyurethane binder, and improve the adhesive strength of the polyurethane binder.
