AH Plus根管充填糊剂临床疗效的观察

观察AHPlus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AHPlus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3d和7dAHPlus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]。AHPlus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。

Application of AH Plus root canal filling paste in root canal therapy

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 day8. 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 months92. 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.
