摘要 目的探讨不同类型牙本质湿粘接剂形成的粘接界面的微观特点。方法分别用两类5种牙本质湿粘接系统将Ch-rism a B20树脂粘接在新鲜的人牙本质上,通过TEM的观察,分析不同类型湿粘接系统形成的粘接界面的特点。结果五种粘接系统在湿粘接时都可以形成比较理想的粘接界面。粘接剂可以渗透到牙本质表面和牙本质小管周围脱矿形成的胶原纤维网中,形成混合层;粘接剂同时渗入牙本质小管和部分侧枝小管中,形成树脂突。以酒精和水为溶剂的粘接系统形成的粘接界面中存在过度润湿现象,即在粘接界面中存在大小不一的水泡状结构,提示此时界面的密封性降低,并影响到最终的粘接强度。结论润湿状态可以很好的保持脱矿后胶原纤维的网状结构,从而于利于粘接剂的渗透,形成较为理想的粘接界面,提高粘接强度。 Objective To analyze the bonding interface characteristics of different types of wet bonding systems. Method Five wet bonding systems, including two alcohol-water-based and three acetone-based systems, were used to bond Chrisma B20 composite resin on the fresh human dentin, and the bonding interface were observed with TEM 2000EX. Results All five bonding systems were infiltrated into the collagen fibril net of demineralized dentin. Hybrid layer was formed in demineralized dentin and around the lateral branch of dentinal tubule. The thickness of hybrid layer was about 3 - 5μm. There was over wetting phenomenon in the bonding interface of alcohol-water-based adhesives. Conclusion Moisture can maintain the structure of collagen fibril net, the infiltration of adhesives and the increasing of bonding strength.
