连续波充填技术的临床评价

Clinical Evaluation of Continuous Wave of Condensation Technique in Root Canal Obturation

目的评价连续波充填技术的临床疗效。方法选择牙髓病或根尖周病患者60例,按就诊顺序随机分为两组,分别采用连续波充填技术(CW组)和冷牙胶侧方加压充填技术(LC组)进行根管充填。术前、术后拍摄X线片。比较两组的根管充填时间、术中疼痛情况和根管充填效果。结果以牙为单位,CW组适充28例,超充1例,欠充1例;LC组中,适充27例,超充2例,欠充1例。CW组术中不适4例,LC组2例。以根管为单位,CW组根管充填时间平均每根管65.7s,LC组平均每根管203.8s(P<0.05)。结论连续波充填技术临床操作简便有效,操作时间短。

Objective To evaluate the clinical effects of continuous wave of condensation technique. Methods Sixty patients with pulpitis or periapical periodontitis were divided into two groups randomly, which were obturated by continuous wave of condensation technique（CW） and lateral condensation technique（LC） respectively. Preoperative and postoperative radiographs of each tooth were taken. The obturation time, incidence of pain during obturation and obturation quality were recorded and compared. Results One case of overfilling was found in CW group, while 2 cases in LC group. 4 cases were found pain during obturation in CW group, while 2 cases in LC group. The average obturation time per root canal of CW and LC were 65.7 seconds and 203.8 seconds respectively （P〈0. 05）. Conclusion Continuous wave of condensation technique is more adaptable to root canal obturation.
