摘要
目的:探讨不同根管填充材料的封闭性能。方法:应用计算机检索维普数据库中与根管填充材料封闭性有关的文献,检索时限1998-01/2009-10。中文关键词:根管充填材料,微渗漏,封闭性。对资料进行初审,并查看每篇文献后的引文,共入选相关文献23篇。结果:糊剂类根管充填材料种类繁多,包括氧化锌丁香油类、氢氧化钙类、树脂类、生物材料类等。糊剂类根管充填材料是根管封闭良好不可缺少的材料,它用来充填根管壁和固体根管充填材料之间的间隙,以及侧副根管、峡部以及不规则的根管系统,可提高根管充填的封闭性。综合比较各种根管充填材料的封闭性能.目前还没有一种材料能达到百分之百的封闭效果。目前研究的热点集中于纳米材料、黏接性封闭剂材料以及不同充填方法的应用等。结论:随着牙科材料学的长足发展,根管充填材料得以不断改进和更新,相信在今后的临床工作中,一定会找到更优质、更完善的充填材料,为理想的根管充填创造条件。
OBJECTIVE：To study the sealing properties of different materials for root canal filling.METHODS：A computer search was performed in VIP database for articles related to the sealing of root canal filling materials,published from January 1998 to October 2009.Chinese keywords are root canal filling materials,micro-leakage,sealing.After the first trial,each article citation was checked,and a total of 23 literatures were selected.RESULTS：There are a wide range of paste materials for root canal filling,such as zinc oxide eugenol,calcium hydroxide,resin,biological materials and others.Paste type root canal filling material is essential for good root canal filling,it is used to fill the gap between root canal wall and solid root canal filling material,as well as the collateral canal,the isthmus and the irregular root canal system,it can improve the sealing performance of root canal filling.By comprehensive comparison of the sealing performance of different root canal filling materials,none of these materials can acquire100% sealing effect.Current researches focus on nano-materials,bonding sealant materials and different methods of filling. CONCLUSION：With the rapid development of dental materials science,the root canal filling material can be continuously improved and updated.A better and more complete filling material is promising in future clinical work,so as to create the ideal conditions for root canal filling.
