Clinical and laboratory assessment of a new root canal filling material--Resilon-Epiphany system.
In 21 patients, 48 root canals were filled using a single-cone method or lateral condensation technique of gutta-percha with addition of Epiphany sealer. Laboratory investigations were performed on 4 extracted one-root human teeth, which were prepared by means of a crown-down technique and obturated with Resilon-Epiphany using System B and Obtura II. Next, the roots were transversely cross-sectioned in the mid-length at a 2 mm distance from the apex and analysed in SEM.
After a year, the treatment proved to be clinically and radiologically successful in all the patients. SEM analyses revealed good adhesion of Epiphany sealer to the canal walls with visible tags in dentine tubules. Good adherence was also found of Epiphany to Resilon and Resilon to root dentine, but few gaps were also observed.
Our preliminary positive results require more thorough evaluation, longer observation period and a larger group of patients. However, they allow the assumption that resin-percha will successfully replace gutta-percha in the nearest future.
对一种新型根管充填材料——Resilon-Epiphany系统进行临床和实验室评估。
对21例患者的48个根管采用单锥法或牙胶尖侧方加压技术并添加Epiphany封闭剂进行充填。对4颗拔除的单根人牙进行实验室研究，采用冠向下技术预备根管，并用System B和Obtura II使用Resilon-Epiphany进行充填。然后，将牙根在距根尖2 mm处的中部横向截断，在扫描电子显微镜下进行分析。
一年后，所有患者的治疗在临床和影像学上均取得成功。扫描电子显微镜分析显示，Epiphany封闭剂与根管壁有良好的黏附，在牙本质小管中有可见的标签。还发现Epiphany与Resilon以及Resilon与牙根牙本质之间有良好的黏附，但也观察到一些间隙。
我们初步的阳性结果需要更全面的评估、更长的观察期和更大的患者群体。然而，这些结果使我们可以假设，树脂牙胶在不久的将来将成功取代传统牙胶。
