表面酸蚀对自粘接树脂水门汀粘接牙齿强度的影响
|
摘要
目的:研究对比磷酸酸蚀牙釉质与牙本质前后,Rely X U200自粘接树脂水门汀对Vita MarkⅡ陶瓷与牙的粘接强度。方法:分别制备20个牙釉质块(A组)和20个牙本质块(B组),各组随机分成2组;制备40个瓷块,随机分成4小组;从各组中随机抽取一小组样本表面用磷酸酸蚀(A_(EH)组和B_(DH)组),另外一小组不酸蚀(A_E组和B_D组),用Rely X U200将各小组牙块与Vita MarkⅡ陶瓷进行粘接,测量其剪切强度,体视显微镜观察其断裂界面。结果:A_(EH)组和A_E组的剪切强度(MPa)分别为22.20±2.85和12.37±2.98(P<0.05),界面破坏分别为1例和5例,混合破坏分别为9例和5例;B_(DH)组和B_D组的剪切强度分别为7.30±2.43和10.71±2.02,界面破坏分别是8例和7例,混合破坏分别为2例和3例。结论:表面酸蚀可增强自粘接树脂水门汀与釉质的粘接强度,降低牙本质的粘接强度。牙釉质界面破坏主要为混合破坏,牙本质界面主要为粘接界面破坏。
Objective:To compare the shear strengths of Vita Mark II ceramic blocks bonded to enamel and dentin with and without etching respectively by self-adhesive resin cement of Rely X U200.Methods:20 enamel slices(group A)and 20 dentin slices(group B)were respectively divided into 2 groups.10 slices of each group were etched by phosphoric acid,then 40 Vita Mark II ceramic blocks were respectively bonded to the slices,the sample were grouped into A_E(without etching),A_(EH)(with etching),B_D(without etching)and B_(DH)(with etching),shear strength of the samples was measured and the failure types were evaluated after debonding.Results:The shear strength(MPa)of group A_(EH)and A_Ewas 22.20±2.85 and 12.37±2.98(P<0.05),that of group B_(DH)and B_D7.30±2.43 and 10.71±2.02(P<0.05),respectively.Tooth-adhesive interfacial failure was observed in 5,1,7 and 8,mixed failure in 5,9,3 and 2 cases of group A_E,A_(EH),B_Dand B_(DH)respectively.Conclusion:Acid etching for enamel bond to ceramic by selfadhesive resin cement Rely X U200 may increase the bonding strength.Mixed failure is the main type of debonding,that for dentine may decrease the bonding strength and interface failure in the main type of debonding
