观察AH Plus根管充填糊剂在根管治疗术中的疗效.选择临床424个需要进行根管治疗的患牙,按随机数字表随机分为两组,每组212个患牙,比较AH Plus糊剂(实验组)和氧化锌丁香油糊剂(对照组)根管充填,疗效.根管充填术后3 d和7 d AH Plus糊剂组疼痛发生率均明显低于氧化锌丁香油糊剂组[8.5%(18/212)比15.6%(33/212),5.2%(11/212)比14.6%(31/212),均P＜0.05],术后6个月及12个月的成功率差异均无统计学意义[92.5%(196/212)比89.6%(190/212),91.5%(194/212)比88.7%(188/212),均P＞0.05].AH Plus糊剂与氧化锌丁香油糊剂比较,根管治疗术成功率无差异,但术后疼痛反应小.%To compare the postobturation pain and therapeutic effects in root canal therapy between two root canal filling materials: AH Plus and zinc oxide eugonol. Four hundred and twenty four teeth requiring root canal therapy were randomly divided into 2 groups: AH Plus ( trial group ) or zinc oxide eugonol ( control group) were used in treatment respectively. The pain intensity after treatment was evaluated by visual analogue scale. The therapeutic effects were evaluated by follow-up for 6 and 12 months. The pain intensity of trial group was significantly lower than that of the control group in 3rd and 7th day[8. 5% ( 18/212) vs. 15.6% (33/212),5.2% (11/212) vs. 14.6% (31/212),both P ＜0.05]. There were no significant differences in effictive rate between two groups after follow-up for 6 and 12 months[92. 5% ( 196/212) vs. 89. 6% ( 190/212 ) ,91.5% ( 194/212 ) vs. 88.7% ( 188/212 ), both P ＞ 0. 05]. AH Plus root canal filling paste used in root canal therapy can significantly decrease postoperative pain.
