充填

BACKGROUND: Glass ionomer cement has been a commonly used filling material in the clinic. However, glass ionomer easily absorbs water and dissolves in early concretionary phase, which can reduce the leak tightness of the edge of obturator, resulting in slightly leakage.

背景：玻璃离子水门汀目前已发展成为临床常用的充填材料，但玻璃离子在凝固的初期易吸水溶解的特性，会使充填体边缘密封性减低，产生微渗漏。

Methods: 60 patients with isolated anterior teeth used zinc oxide paste and iodoform gutta-percha point for lateral condensation, then the experimental group had the root canal filling pressure into FRC pile nail, the control group would no longer be dealing with, two groups had apical dye leakage test.

This type is accompanied by the structure-salt dissolution breccias,being vein or flamboyancy in cross section while some of them shot through the lead and zinc ore. In fact,the breccias were lead and zinc orebodies themselves.

其角砾成分单一(主要为沥青质灰岩、晶质灰岩)、大小混杂(nmm～nX10m)、无分选，角砾多呈不规则状和次棱角状或次浑圆状，部分角砾具有可拼性，角砾间为砂质充填或无充填，表明它是一套构造和膏溶共同作用形成的角砾岩。

The results indicated that most majority tourmaline has the filling phenomenon.The filling may assume white or yellow flocculus, blue flash and flow structures inside.Even organics and lead can be found still on the sample which has unnoticeable filling by IR and XRF testing.

结果表明，绝大多数碧玺都存在充填现象，充填物可呈白色絮状物、黄色絮状物、蓝色闪光、流动构造等存在于碧玺内部，有些不明显的碧玺样品，在红外及QUANT'X 型荧光能谱仪下仍然有有机物及Pb峰的存在。

Results: The chair-side time of two, three and four root canals was decreased obviously in four-handed technique group when root canals were obturated. There was no statistical difference in single root canal between two groups.

结果：单根管充填时两组医生的椅旁操作时间无明显差异，双根管、三根管及四根管充填时医生的椅旁操作时间有显著性差异。

The warm gutter filling can achieve good results because of the easy changeable of gutta-percha in softening states.

热牙胶充填是利用牙胶在加热软化时能够顺应管壁的复杂形态，进入管腔的不规则间隙，达到较理想的充填效果。

There was no significant difference in microleakage between differently tapered gutta-percha using continuous wave of condensation technique.

连续波充填技术微渗漏小于侧方加压技术，不同锥度牙胶配合连续波充填技术的微渗漏无显著性差异。

CPC and traditional root canal filling paste gutta percha point were used in treament of root canal filling on 120 roots. The cases were followed up for 1~2 years.
