J Endod:Resilon:评估未愈合病例中的降解充填材料

Resilon封闭系统(Pentron Clinical Technologies, Wallingford, CT)作为常规牙胶和封闭剂的替代产品断断续续的应用数年。体外模型研究报道Resilon充填材料具有降解性;然而,之前没有临床研究显示这种降解的存在。这可能代表着对患者健康更加密切的关注以及使用Resilon封闭根管可能会导致更高的临床失败。这篇研究的目的是为了评估在未愈合牙髓病例中Resilon降解的比例,并与牙胶和封闭剂相对比。

研究纳入了之前曾使用Resilon或牙胶进行治疗但根管未愈合并且需要再治疗的患者。基于通路的建立,将之前的充填材料分为降解或完整。充填材料降解的指标为:根管内缺乏密实的材料而使15号K锉可以直达工作长度。

结果显示,2种材料降解的比例存在显著性差异,二变量分析显示,Resilon降解的可能性明显高于牙胶(P = .0003)。

结论:这篇临床观察研究显示,与牙胶相比,在未愈合病例中Resilon降解的比例更高。
