GuttaFlow？ 2充填系统与热牙胶充填系统对根管充填临床疗效的比较
|
Abstract:
摘要 目的:GuttaFlow？ 2常温流动牙胶充填技术与热牙胶充填进行对比,观察其临床疗效,为临床应用提供参考.方法:将115例患牙系统随机分为2组.实验组57例患牙,共162个根管,用GuttaFlow？ 2加大锥度牙胶尖充填根管;对照组58例患牙,共166个根管,用AH-PLUS加大锥度牙胶尖热牙胶充填根管.记录2组根管充填时间,通过数字化牙片评价根管充填质量并观察患者充填术后疼痛反应情况.结果:对照组的前牙组和后牙组根管充填时间均显著高于实验组(P<0.01);2组数字化牙片根管充填效果无统计学差异(P>0.05);实验组术后疼痛仅1例(2.33%),经观察后疼痛消失.对照组术后疼痛7例(17.50%),其中6例轻度疼痛经观察后疼痛消失,1例中度疼痛经调合后疼痛缓解.结论:GuttaFlow？ 2常温流动牙胶在保证临床充填质量的前提下,可明显减少充填时间,减轻患者术后疼痛.但GuttaFlow？ 2的长期封闭效果仍有待进一步研究.
