【摘要】：目的:对比4种树脂水门汀粘结Ceramage聚合瓷嵌体后的微渗漏,为临床选择树脂水门汀提供参考。方法:40个离体无龋前磨牙按嵌体制洞原则制备近中邻牙合面洞,Ceramage聚合瓷制作树脂嵌体后随机分为4组(n=10),分别使用Rely X ARC、Rely X Unicem、Panavia F、ResiCem 4种树脂水门汀粘结嵌体。经冷热循环500次品红染色后,金刚砂片平行于牙体长轴沿近远中方向将修复体纵向剖开2次,在体视显微镜下测量染料渗入轴壁、颈壁的深度。结果:在轴壁4种材料微渗漏长度差异有统计学意义(F=8.04,P0.05);Rely X Unicem组的微渗漏值高于Rely X ARC组(q=6.56)、Panavia F组(q=5.579)、ResiCem组(q=5.158),差异有统计学意义(P0.05),其他3组间差异无统计学意义(P0.05)。颈壁:不同材料间的微渗漏差异无统计学意义(F=2.112,P0.05);同材料组的颈壁渗漏程度均显著高于轴壁(P0.05)。结论:Rely X Unicem对釉质的封闭效果较差;Rely X ARC、Panavia F、ResiCem均是粘结树脂嵌体理想的粘结剂。
[Abstract]:Objective: to compare the microleakage of four kinds of resin cement bonded Ceramage polymeric porcelain inlay. Methods: 40 non-caries free premolars were prepared according to the principle of embedded cavity. Ceramage polymeric porcelain was randomly divided into 4 groups after making resin inlay, and Rely X ARCU Rely X Unicemer Panavia F was used respectively. ResiCem four kinds of resin cement cementing inlay. After 500 times of fuchsin dyeing under the cold and hot cycle, the carborundum slice was cut into longitudinally two times along the long axis of the tooth. The depth of dye penetration into the axial wall and neck wall was measured under stereoscopic microscope. Results: there were significant differences in the microleakage length of the four materials in the axial wall. The microleakage value of Rely X Unicem group was higher than that of Rely X ARC group (P < 0.05). In ResiCem group, there was a significant difference (P 0.05). There was no significant difference among the other three groups (P 0.05), but there was no significant difference in microleakage between different materials (P 0.05). The degree of neck wall leakage in the same material group was significantly higher than that in the axonal wall (P0.05A). Conclusion the sealing effect of Unicem on enamel is worse than that in the same material group. Rely X ARCU Panavia FIB Cem is an ideal binder for adhesive resin inlay.
