目的
确定表面处理对两种树脂水泥（ParaPost Cement 和 Panavia F）与钛合金桩（ParaPost XH）、玻璃纤维（ParaPost Fiber White）和氧化锆（Cerapost）以及牙本质的粘结强度的影响。
材料和方法
包埋后，通过研磨获得柱子（n = 9 至 14）和人牙本质（n = 10）的平坦表面。柱子接受三种表面处理之一：1. 粗糙化（喷砂、氢氟酸蚀刻），2. 涂底漆（合金底漆、金属底漆 II、硅烷），或 3. 粗糙化后涂底漆（喷砂或蚀刻，然后涂底漆、Cojet 处理）。将 ParaPost 水泥和 Panavia F 粘合到桩和牙本质标本上，并将粘合的标本置于 37 摄氏度的水中 7 天。样品在剪切作用下脱粘。
结果
Panavia F 与 ParaPost XH、Cerapost 和牙本质的粘合强度明显高于 ParaPost 水泥。大多数表面处理都提高了树脂水泥与柱子的粘合强度。与地面对照相比，Cojet 处理和喷砂是最有效的处理方法。使用氢氟酸蚀刻 Cerapost（经过或不经过硅烷处理）会显着降低 Panavia F 与桩的粘合强度。
结论
树脂水门汀与立柱的粘合强度受立柱材料、立柱表面处理以及树脂水门汀类型的影响。树脂水门汀与牙本质的粘合强度受树脂水门汀类型的影响。
PURPOSE
To determine the effect of surface treatments on bond strength of two resin cements (ParaPost Cement and Panavia F) to posts of titanium alloy (ParaPost XH), glass fiber (ParaPost Fiber White), and zirconia (Cerapost), and to dentin.
MATERIALS AND METHODS
After embedding, planar surfaces of posts (n = 9 to 14) and human dentin (n = 10) were obtained by grinding. The posts received one of three surface treatments: 1. roughening (sandblasting, hydrofluoric acid etching), 2. application of primer (Alloy Primer, Metalprimer II, silane), or 3. roughening followed by application of primer (sandblasting or etching followed by primer, Cojet treatment). ParaPost Cement and Panavia F were bonded to the post and dentin specimens, and the bonded specimens were placed in water at 37 degrees C for 7 days. The specimens were debonded in shear.
RESULTS
Panavia F had significantly higher bond strength to ground ParaPost XH, Cerapost, and dentin than did ParaPost Cement. Most surface treatments resulted in an improved bond strength of resin cements to the posts. Compared to the ground control, Cojet treatment and sandblasting were the most effective treatments. Etching of Cerapost with hydrofluoric acid with and without silane treatment significantly decreased the bond strength of Panavia F to the post.
CONCLUSION
The bond strength of resin cements to the posts was affected by the material of the post, the surface treatment of the post, and by the type of resin cement. The bond strength of resin cement to dentin was influenced by the type of resin cement.
