Endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to Gutta-percha in respect to obturation procedure. The aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system.
A total of 42 teeth were selected and were divided into four groups. Two experimental groups consisted of 15 teeth each and positive control group consisted of eight teeth and negative control group consisted of four teeth. In the experimental groups, Group 1 was obturated with resilon/epiphany system and Group 2 was obturated with Gutta-percha and endofil sealer by lateral condensation technique. The teeth were then immersed in Methelene blue solution and were split longitudinally to access the amount of dye penetrated in the canal. The specimens were viewed under scanning electron microscope to evaluate the adhesion of the obturating material to the root canal walls. Data was subjected to statistical analysis by Analysis of Variance and Bonferroni multiple comparison test at 1% level of significance.
The resilon/epiphany system showed better adaptation to the root canal walls, but the difference in dye penetration was not statistically significant when compared to specimens obturated with Gutta-percha and endofil sealer.
Although, there was no statistically significant difference between the groups, but resilon/epiphany system showed better adaptation to the root canal walls.
牙髓病学中关于根管渗漏的研究主要集中在根管系统根尖封闭的质量上,新引入的瑞速安/依必安系统在根管充填过程中据称优于牙胶。本研究的目的是评估用瑞速安/依必安系统完成的根管充填情况。
共选取42颗牙齿,分为四组。两个实验组每组15颗牙齿,阳性对照组8颗牙齿,阴性对照组4颗牙齿。在实验组中,第1组用瑞速安/依必安系统进行充填,第2组用牙胶和根管封闭剂通过侧向加压技术进行充填。然后将牙齿浸泡在亚甲蓝溶液中,并沿纵向劈开以观察染料渗入根管的量。在扫描电子显微镜下观察标本,以评估充填材料与根管壁的黏附情况。数据采用方差分析和Bonferroni多重比较检验进行统计学分析,显著性水平为1%。
瑞速安/依必安系统显示出对根管壁更好的适应性,但与用牙胶和根管封闭剂充填的标本相比,染料渗入的差异无统计学意义。
虽然各组之间无统计学显著差异,但瑞速安/依必安系统对根管壁显示出更好的适应性。
