It is treated with six fields (Anterior, Posterior, four obliques) positioned 60° apart around the circumference of the patient, each dual field is made up of two component beams, pointing ±15° with respect to the horizontal. The nominal energy of electron beam produced by Mevatron Ⅻ is 3MeV, and the patient is treated at a distance of 3 meters. Using Capintec dosemeter and PS-033 electron beam chamber for measurement, one moniter unit of radiation is equivalent to 0.0127cGy. Measurement of electron energy by Kodak X-omat-V verification film inside the Rando phantom at 100 cm SSD was 3.70MeV, electron energy measured at 3 meters was 3.51MeV. X-ray contamination was measured as 9.5% per six dual fields.

此种方法分别使用六个双照野，由病人的前、后、左前、右前、左后、右后各间隔60度共六个方向照射，每一双照野由水平向上和向下15度照射；荣民总医院选择3MeV电子射束来治疗病人，治疗距离为3公尺，利用擬人假体及柯达X-omat-V验证片实验得电子射束初始能量从3.7Mev变为3.51MeV，六个双照野之X光污染共达9.5%，使用Capintec剂量表及PS-033型电子射束用游离腔测量六个双照野，每一监测单位相当於0.00127 cGy。

上半规管拱峰与内听后壁的直线距离为(7.03±0.26)mm(6.01~7.85mm)，距前壁为(14.44±0.76)mm(12.03~15.77mm)。

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。
