不同根管封闭剂导致根充术后疼痛情况的比较分析

Postoperative pain after one-visit root canal therapy with three root canal sealers

目的比较3种不同根管封闭剂在热牙胶一次法根管治疗术后短期疼痛的发生情况。方法将明确诊断为急慢性牙髓炎需要行根管治疗的恒磨牙240颗随机分为3组:A组以碘仿氧化锌丁香油为封闭剂,B组以碧兰为封闭剂,C组以AH-plus为封闭剂,以连续波技术联合高温牙胶热塑注射充填技术进行一次法根管治疗。对术后24～72h疼痛发生情况用Mohd Sulong评价标尺记录,并用χ2检验分析比较。结果 3组术后疼痛发生率的差异有统计学意义(P<0.01),碧兰组和AH-plus组术后反应较轻且两组之间差异无统计学意义(P>0.05),碘仿氧化锌丁香油组术后疼痛发生最严重。结论以碧兰糊剂和AH-plus糊剂为封闭剂进行热牙胶一次法根管治疗术后疼痛发生的几率比较低。
