EDTA对瓷贴面与牙本质粘接的剪切强度耐久性的影响
|
摘要
目的探讨乙二胺四乙酸(EDTA)预处理对瓷贴面与牙本质粘接的剪切强度耐久性的影响。方法选取完整拔除的无龋坏人类第三恒磨牙90颗,按牙本质表面预处理方式及是否模拟老化分18组(n=5)。粘接面分别采用37%磷酸或(和)17%EDTA预处理后,用Variolink Veneer粘接IPS e.max Press瓷贴面。冷热循环6 000次用于模拟老化实验。电子万能力学试验机测试即刻及老化实验后的试件剪切强度。扫描电镜下观察试件的破坏模式。结果 37%磷酸(15s)+17%EDTA(30s)预处理获得最高的即刻剪切强度[(15.41±2.83)MPa],且具有粘接耐久性(P=0.148)。试件的破坏模式大部分呈现界面破坏。结论 EDTA在瓷贴面与牙本质粘接的剪切强度耐久性方面具有重要作用。
Objective To study the effects of ethylene diamine tetraacetic acid(EDTA)pretreatment on durability of shear bond strength of porcelain veneer to dentin.Methods A total of 90 freshly extracted intact human third molars without caries were collected,and randomly divided into 18 groups(n=5)according to different pretreatment and either without or with aging test.All the adhesive interfaces were pretreated with37% phosphoric acid or(and)17% EDTA.Then Variolink Veneer cement was used to bond IPS e.max press porcelain veneer on the prepared adhesive interfaces.The mocycling test for 6 000 times was chosen to simulate aging.Immediate and aging shear bond strength were tested by electronic universal mechanical machine.The damage of specimens was observed under scanning electron microscope.Results Dentin pretreatment with 37% phosphoric acid(15 s)+17% EDTA(30 s)exhibited the highest shear bond strength of porcelain veneer to dentin[(15.41±2.83)MPa]and bond durability(P=0.148).Most specimens showed interface damage.Conclusion EDTA plays an important role on the durability of shear bond strength of porcelain veneer to dentin.
