摘 要:目的通过比较Beautifil Flow Plus F00、FiltekTM Z350 XT、SDR、Tetric®N-Flows、Constic 5种流体树脂与牙釉质的粘接性能,为流体树脂的临床选择提供参考。方法选择因正畸拔除的成人离体前磨牙50颗,将离体牙随机分为5组(n=10),分别为F00组、Z350组、SDR组、Tetric组、Constic组,每组之间互为平行对照组。每颗离体牙颊侧中1/3磨除厚度为0.5 mm牙釉质,以直径为3 mm的圆形形态作为粘接面,每种树脂制作直径和长度均为3 mm圆柱形树脂试件10个,与预备好的牙釉质面进行粘接,自凝树脂进行包埋。将试件进行3000次冷热循环交替实验和37℃恒温水浴24 h实验后,进行剪切强度测试,记录数据;切断的粘接界面在扫描电镜下观察。结果F00组的剪切强度为(18.39±2.93)MPa、Z350组的剪切强度(11.03±1.55)MPa、SDR组的剪切强度为(12.77±1.55)MPa、Tetric组的剪切强度为(15.25±1.88)MPa、Constic组的剪切强度为(12.79±2.78)MPa,对所得数据进行ANOVA检验和SNK检验后得出,F00组的剪切强度显著高于其他4组(Z350组、SDR组、Tetric组、Constic组)(P<0.05);Tetric组的剪切强度显著高于其余3组(Z350组、SDR组、Constic组)(P<0.05);Z350组、SDR组、Constic组3组之间的剪切强度没有显著性差异(P>0.05)。结论5种流体树脂中Beautifil Flow Plus F00流体树脂粘接性能最高,Tetric®N-Flow流体树脂次之,FiltekTM Z350 XT、SDR、Constic这3种流体树脂粘接性能较低。Objective To provide reference for clinical selection of fluid resins by comparing the bonding properties of Beautifil Flow Plus F00,FiltekTM Z350 XT,SDR,Tetric®N-Flows and Constic with tooth enamel.Methods Fifty adult extrinsic premolars were selected for orthodontic extraction and randomly divided into five groups(n=10),namely F00 group,Z350 group,SDR group,Tetric group and Constic group,and each group was a parallel control group.One third of the cheek of each isolated tooth was removed by grinding the enamel with the thickness of 0.5 mm,and a circular shape with a diameter of 3 mm was used as the bonding surface.Ten cylindrical resin specimens with a diameter and length of 3 mm were prepared for bonding with the prepared tooth enamel surface,and self-coagulation resin was embedded.After 3000 times of alternating cold and hot cycles and 24 h of constant temperature water bath at 37℃,the shear strength test was carried out;the data were recorded,and the cut bonding interface was observed under scanning electron microscope.Results The shear strength of group F00 was(18.39±2.93)MPa,and that of group Z350 was(11.03±1.55)MPa.The shear strength of,SDR group was(12.77±1.55)MPa;Tetric group was(15.25±1.88)MPa and Constic group was(12.79±2.78)MPa.ANOVA test and SNK test were performed on the obtained data.The shear strength of F00 group was significantly higher than that of Z350 group,SDR group,Tetric group and Constic group(P<0.05).The shear strength of Tetric group was significantly higher than that of Z350 group,SDR group and Constic group(P<0.05).There was no significant difference in shear strength among Z350 group,SDR group and Constic group(P>0.05).Conclusion Among the five fluid resins,Beautifil Flow Plus F00 fluid resin has the highest bonding performance,followed by Tetric®N-Flow fluid resin,and FiltekTM Z350 XT,SDR and Constic fluid resin have low bonding performance.
