Resilon (Resilon Research LLC, Madison, CT) with Epiphany Sealer (Pentron Clinical Technologies, Wallingford, CT) was introduced into the market in 2004 as a new method of root canal obturation. This material as well as the traditionally used gutta-percha with AH Plus sealer (Dentsply Maillefer, Tulsa, OK) were in use over a 9-year span in the University of North Carolina endodontic clinics. Although Resilon was initially thought to create a "monoblock" seal between the material and the canal, in vitro studies later suggested this concept not to be true. The long-term outcome of Resilon using a validated radiographic index and a systematic approach has not been reported. The purpose of this retrospective cohort study was to radiographically evaluate the outcome of Resilon/Epiphany-treated root canals compared with traditional gutta-percha/AH Plus.
One hundred twenty-five teeth were radiographically evaluated using the periapical index; 80 were treated with Resilon and 45 with gutta-percha. Age, sex, tooth position, and number of months to follow-up were documented, and a multivariate analysis with odds ratio was performed.
Resilon-treated teeth were 5.3 times more likely to have a periapical index of 3 to 5 at follow-up compared with gutta-percha (P = .009). Teeth presenting with preoperative lesions, regardless of the material used, were also more likely to present with a lesion at follow-up (P = .04).
Teeth obturated with Resilon were more likely to present with a lesion at follow-up compared with gutta-percha obturated teeth after controlling for the presence of a preoperative lesion and the length to follow-up.
Resilon（Resilon Research LLC，Madison，CT）与 Epiphany 密封剂（Pentron Clinical Technologies，Wallingford，CT）于 2004 年作为一种新的根管填充方法引入市场。这种材料以及传统使用的带有 AH Plus 密封剂的牙胶（Dentsply Maillefer，Tulsa，OK）在北卡罗来纳大学的牙髓诊所使用了 9 年。尽管 Resilon 最初被认为在材料和根管之间形成了“单体”密封，但随后的体外研究表明，这一概念并不正确。使用经过验证的放射学指数和系统方法对 Resilon 的长期结果尚未有报道。本回顾性队列研究的目的是通过放射学评估 Resilon/Epiphany 处理的根管与传统牙胶/AH Plus 的结果。
使用根尖指数对 125 颗牙齿进行放射学评估；80 颗用 Resilon 治疗，45 颗用牙胶治疗。记录年龄、性别、牙齿位置和随访时间，并进行多元分析和比值比。
与牙胶相比，Resilon 治疗的牙齿在随访时更有可能出现根尖指数为 3 到 5 的情况（P=0.009）。无论使用何种材料，术前有病变的牙齿在随访时也更有可能出现病变（P=0.04）。
在控制术前病变和随访时间的情况下，与牙胶填充的牙齿相比，用 Resilon 填充的牙齿在随访时更有可能出现病变。
