The present study aims to evaluate the effectiveness of an XP-endo non-surgical root canal re-treatment system in removing both GuttaCore and Thermafil gutta-percha carrier-based root canal filling materials from straight root canal systems using micro-computed tomography (micro-CT) analysis. The study was performed on 20 single-rooted upper teeth, which were randomly allocated into the following study groups: Group A, Thermafil and AH Plus sealer ( = 10); Group B, GuttaCore and AH Plus sealer ( = 10). Before and after the non-surgical root canal re-treatment procedure, the samples were submitted for a micro-CT analysis. The volume of the root canal filling material (mm), the volume of the remaining root canal filling material (mm) and the time (minutes) needed to remove the root canal filling material were also recorded. Student's -test was used to analyze the results. No statistically significant differences were found between the volume of the remaining root canal filling material in the GuttaCore and Thermafil root canal filling systems at the coronal third ( = 0.782), middle third ( = 0.838) or apical third ( = 0.882) of the straight root canal systems; however, the GuttaCore required a statistically significant ( = 0.037) shorter amount of time (4.72 ± 0.76 min) to be removed than the Thermafil carrier-based root canal filling material (5.92 ± 1.42 min). The XP-endo Finisher non-surgical endodontic re-treatment system removes both GuttaCore and Thermafil gutta-percha carrier-based root canal filling materials from straight root canal systems, although removal of the GuttaCore gutta-percha carrier-based root canal filling material required less time.
本研究旨在通过显微计算机断层扫描（micro-CT）分析，评估XP-endo非手术根管再治疗系统从直根管系统中去除GuttaCore和Thermafil牙胶尖载体类根管充填材料的有效性。该研究在20颗单根上颌牙上进行，这些牙齿被随机分为以下研究组：A组，Thermafil和AH Plus封闭剂（n = 10）；B组，GuttaCore和AH Plus封闭剂（n = 10）。在非手术根管再治疗程序前后，将样本进行micro-CT分析。还记录了根管充填材料的体积（mm）、剩余根管充填材料的体积（mm）以及去除根管充填材料所需的时间（分钟）。采用学生t检验分析结果。在直根管系统的冠方三分之一（P = 0.782）、中间三分之一（P = 0.838）或根尖三分之一（P = 0.882）处，GuttaCore和Thermafil根管充填系统中剩余根管充填材料的体积之间未发现统计学上的显著差异；然而，与Thermafil牙胶尖载体类根管充填材料（5.92 ± 1.42分钟）相比，去除GuttaCore所需的时间在统计学上显著更短（P = 0.037，4.72 ± 0.76分钟）。XP-endo Finisher非手术牙髓再治疗系统可从直根管系统中去除GuttaCore和Thermafil牙胶尖载体类根管充填材料，尽管去除GuttaCore牙胶尖载体类根管充填材料所需时间更少。
