根管充填是根管治疗的一个重要环节,它的目的是对根管系统三维地(three dimension)进行彻底充填,封闭,以促进根尖周组织的修复,消除根管和根尖周再感染的机会。由于根管系统的复杂性和变异性,临床上约60％失败的根管治疗是由根管的充填或封闭不全引起的。因此,很多学者认为,良好的封闭能力对根管封闭剂来说很重要。 玻璃离子(Glass ionomer cement),具备良好的生物相容性和能与牙体组织化学性结合的性能。已被广泛应用于冠桥粘固、牙体修复和衬底等,但应用于根管充填才刚刚开始。本实验采用染料渗入法,与被公认为封闭力最好的材料AH26对比,研究玻璃离子对根尖的封闭能力。
Root canal filling is an important part of root canal therapy. Its purpose is to completely fill and seal the root canal system in three dimensions, so as to promote the repair of the periapical tissue and eliminate the re-infection of the root canal and apical period Opportunity. Due to the complexity and variability of the root canal system, about 60% of failed root canal treatments in the clinic are caused by filling or incomplete root canal filling. Therefore, many scholars believe that good sealing ability is very important for root canal sealing agent. Glass ionomer cement with good biocompatibility and chemical bondability with dental tissues. It has been widely used in the crown bridge fixation, dental restoration and substrate, but the application of root canal filling has just begun. In this experiment, the dye infiltration method was compared with the AH26, which is considered as the best sealing material, to study the glass ionomer's ability to seal the root tip.
