Methods 20 human biscuspids scheduled to be extracted for the orthodontic reasons were prepared for porcelain fused to matal crown,of which every 2 teeth were from the same patient and the same jaw. The teeth were randomly, blindly and self controlly divided into 2 groups.In the control group:the temporary crowns were cemented with zinc oxide cement.In the testing group:Green Or was applied before the temporary crowns were cemented with zinc oxide cement.

选择因正畸治疗需要而计划拔除的20颗前磨牙进行金属烤瓷全冠牙体预备，其中每2颗牙均为同颌同名牙；采用随机、双盲、自身对照设计分为2组：对照组在牙预备体上直接用氧化锌丁香酚水门汀粘固暂时冠；观察组在牙预备体上涂布极固宁TM后用氧化锌丁香酚水门汀粘固暂时冠。

In calculated crime of joint crime, the paper discusses on the relationship between collusion without perpetration and calculated crime and points out that the person who only colludes but does not perpetrate belongs to co-offender and usually not belongs to co-principal offender.

RESULTS: After root canal preparation, the mean value of the angles of canal curvature decreased from 36.21° to 21.98°, while the mean value of the radius of the canal curvature increased from 6.25mm to 11.35mm; the canal axes transported and intercrossed with the original axes at 2 points and created 3 intersection zones.

结果：根管预备完毕，根管弯曲角度均值从预备前的36.21°逐渐减小至21.98°，弯曲半径均值从6.28mm增大至11.35mm；根管长轴发生了偏移，与预备前原根管长轴形成2个交点，3个相交区。

The curved line, linking the coordinates of point C, likes a "V" toward the outer of the primary curve. CONCLUSION: the straitening phenomenon was evident in preparation of S-shaped canals with hand-used Pro-Taper, and occurred mainly after instrumentation by F1 file.

Group 1 was instrumented with SS-K files by step-back technique, group 2 was instrumented with manual Protaper instruments according to manufacturers' directions.

第一组使用不锈钢K锉采用逐步后退法预备近颊根管，第二组使用手用Protaper采用厂家推荐的方法预备近颊根管，第三组使用机用K3采用逐步深入法预备近颊根管。

Methods: One hundred and twenty teeth with curved root canals were randomly divided into 2 groups: 74 curved root canals in group PT were prepared by ProTaper rotary Nickel-Titanium file with crown-down technique, and 75 curved root canals in group SS were prepared by K-files with step-back technique.

选择2005年6月至12月间本院口腔内科行根管治疗的120例患者（120颗牙），随机分为两组：试验组用ProTaper机用镍钛锉及冠根向预备技术预备弯曲根管74个，对照组用不锈钢K型锉及逐步后退法技术预备弯曲根管75个。

Objective To evaluate clinical effect of the handling ProTaper Nickel-titanium rotary instruments in preparation of canals of posterior teeth.Methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling ProTaper rotary instruments using step-down technique,and by K files using step-back technique for control.All teeth were obturated with lateral condensation methods.The efficiency of preparation was analyzed with ra-diographs before and after operation.

目的 评价手用ProTaper预备后牙根管的临床效果方法选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用ProTaper 锥度镍钛旋转器械逐步伸入法预备根管，对照组用K锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗后的X线片，评价后牙根管预备效果。
