目的分析长期水储存条件下玻璃陶瓷与牙本质间树脂粘接界面劣化的薄弱点。方法选择完整健康的第三磨牙获得牙本质表面，表面分别接受酸蚀-冲洗型树脂粘接系统One-step Plus＋Duolinks（OD）；自酸蚀型树脂粘接系统ED-Primer＋Panavia F（EP）、 Multilink Primer＋Multilink Automix（MM）、 J-100P Primer＋J-100P Ivory（JJ）；自粘接型树脂水门汀Relyx Unicem（RU）处理后，与表面经硅烷偶联剂预处理的玻璃陶瓷块（ProCAD）进行粘接，经光照射后将瓷块切割成粘接面积约为0.9 mm×0.9 mm的拉伸试件，经过18个月水储存后，接受拉伸测试。结果拉伸试件断裂形式分析显示，单纯的陶瓷界面断裂形式所占比例： OD组64%， EP组57%， MM组79%， JJ组36%， RU组39%，而单纯的牙本质界面断裂形式所占比例： OD组0%， EP组14%， MM组4%， JJ组7%、 RU组14%，其余为涉及陶瓷界面的混合断裂形式。粘接强度结果显示， OD组（12.98±5.86）MPa高于MM组（9.32±2.87）MPa，其差异具有统计学意义（P＜0.05），但其余3组与OD组和MM组的差异无统计学意义（P＞0.05）。结论在长期水储存下，树脂与玻璃陶瓷粘接界面比牙本质与树脂粘接界面更容易出现老化，酸蚀-冲洗型树脂粘接系统能够获得更稳定的牙本质树脂粘接界面。
目的分析長期水儲存條件下玻璃陶瓷與牙本質間樹脂粘接界麵劣化的薄弱點。方法選擇完整健康的第三磨牙穫得牙本質錶麵，錶麵分彆接受痠蝕-遲洗型樹脂粘接繫統One-step Plus＋Duolinks（OD）；自痠蝕型樹脂粘接繫統ED-Primer＋Panavia F（EP）、 Multilink Primer＋Multilink Automix（MM）、 J-100P Primer＋J-100P Ivory（JJ）；自粘接型樹脂水門汀Relyx Unicem（RU）處理後，與錶麵經硅烷偶聯劑預處理的玻璃陶瓷塊（ProCAD）進行粘接，經光照射後將瓷塊切割成粘接麵積約為0.9 mm×0.9 mm的拉伸試件，經過18箇月水儲存後，接受拉伸測試。結果拉伸試件斷裂形式分析顯示，單純的陶瓷界麵斷裂形式所佔比例： OD組64%， EP組57%， MM組79%， JJ組36%， RU組39%，而單純的牙本質界麵斷裂形式所佔比例： OD組0%， EP組14%， MM組4%， JJ組7%、 RU組14%，其餘為涉及陶瓷界麵的混閤斷裂形式。粘接彊度結果顯示， OD組（12.98±5.86）MPa高于MM組（9.32±2.87）MPa，其差異具有統計學意義（P＜0.05），但其餘3組與OD組和MM組的差異無統計學意義（P＞0.05）。結論在長期水儲存下，樹脂與玻璃陶瓷粘接界麵比牙本質與樹脂粘接界麵更容易齣現老化，痠蝕-遲洗型樹脂粘接繫統能夠穫得更穩定的牙本質樹脂粘接界麵。

Objective To analyze the weak point of multiple adhesive interfaces between dentine and glass ceramic through resin cement under long-term water storage. Methods The flat dentin surfaces of 15 intact human third molars and 15 pieces of glass ceramic(ProCAD) pretreated by silane coupler were prepared. The teeth were divided into 5 groups randomly, were bonded with ceramic through etch-rinse type resin adhesive system One-step Plus+Duolinks(OD); self-etch type resin adhesive system ED-Prime+Panavia F(EP), Multilink Primer+Multilink Automix(MM), and J-100P primer+J-100P Ivory(JJ); self-adhesive type resin cement Relyx Unicem(RU). The bonded teeth were sectioned to obtain bar-shaped intact specimens with about 0.9 mm × 0.9 mm bond area. Specimens were kept in distilled water for 18 months, and received mirco-tensile test. Results The count of fracture mode showed that ceramic interface fracture were 64% in Group OD, 57% in Group EP, 79% in Group MM, 36% in Group JJ, 39%in Group RU, while dentine interface fracture were 0% in Group OD, 14% in Group EP, 4% in Group MM, 7% in Group JJ, 14% in Group RU, and the others were the mixture fracture which all included the part of ceramic interface fracture. The bond strengths of Group OD (12.98±5.86) MPa was greater than those of Group MM (9.32±2.87) MPa (P<0.05), and the bond strength of Group EP, Group JJ and RU were not significantly different from Group OD and Group MM(P>0.05). Conclusion The interface of resin cements and ceramics is more susceptible from water than that of resin and dentine, etch-rinse type resin bond system could obtain more stable adhesive interface.
