OBJECTIVE: To compare the sealing capability between the standard gutta-percha point and Thermafil warm gutta-percha.

目的：比较临床常规使用的标准牙胶尖和Thermafil热牙胶两种根管充填材料的根管封闭性能。

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.

采用自固化磷酸钙根管充填剂和传统的充填剂分别应用于随机选择的两组做根管治疗的患牙随访观察1～2年。

Crowndown technique was applied in root canal preparation for all cases. The accuracy of the two methods was evaluated and compared with No 30 film of guttapercha point.

两组均采用冠向下技术进行根管预备，插30#牙胶尖拍片评价2种方法测量根管工作长度的准确性并进行比较。

It showed that the halophile of Kenyu7 were better than Wuming-5;(2)the contents of proline of the two Zea mays varieties increased significantly,and under high NaCl stress(150mmol/L NaCl or above) the increasing amount of the contents of proline of Kenyu7 was higher than Wuming-5 ,so it showed that the injuries of Wuming-5 imposed by NaCl stress was greater than Kenyu7;(3)the activities of CAT of the two varieties were no obviously changed,while the activities of CAT of Wuming-5 were all higher than Kenyu7 under all concentrations of NaCl solution,which hadn't showed the correlation between the activity of CAT and salinity tolerance.

结果表明，随NaCl溶液浓度的增加：（1）两品种玉米生长均受到严重抑制，发芽势降低，芽和根的长度均呈减小的趋势，总体来看，杂交种垦玉7的发芽势、芽和根的长势均好于自交系无名-5；（2）两品种玉米体内Pro含量均增加，且在NaCl浓度超过150mmol/L时，杂交种垦玉7体内Pro含量增加的幅度明显大于自交系无名-5，而使垦玉7对盐的适应能力强于无名-5；（3）两品种的CAT活性变化幅度均不大，但无名-5的CAT活性在各NaCl浓度条件下均高于垦玉7，这可能是由品种间本身差异造成的，而与品种的耐盐性无直接关系。
