Abstract

Aim: To assess the bacterial leakage of two bioceramic sealers and compare them to an epoxy resin-based sealer. Methodology: A sample of 94 one-rooted premolars was obtained and separated into three experimental groups of 30 teeth; two samples were used for negative controls and two for positive controls. The experimental groups were obturated using the hydraulic compaction technique: Group 1, AH Plus® sealer, Group 2, Bioroot® RCS and Group 3, TotalFill® BC Sealer. The teeth were mounted on bacterial leakage devices and incubated at 37 °C for 30 days in a bilin esculin agar culture with Enterococcus Faecalis. Results: Leakage occurred in 27 roots (30%) of the entire sample. Group 1 (AH® Plus) showed the highest percentage of leaked samples (40%) and also took the least average days to leak (16,9) compared to Bioroot® (19,7) and TotalFill® (19,5), but the differences found were not significant (p>0,05). Conclusions: None of the sealers analyzed in this study produced an effective apical seal in which no bacterial leakage occurred. A third of the total sample presented leakage, but the differences between groups were not significant.

生物陶瓷封口剂的细菌泄漏评估

目的:评价两种生物陶瓷封口剂的细菌渗漏情况，并与环氧树脂封口剂进行比较。方法:选取94颗单根前磨牙，分为3组，每组30颗;阴性对照两份，阳性对照两份。实验组采用水力压实技术进行封闭:第1组，AH Plus®密封剂，第2组，Bioroot®RCS，第3组，TotalFill®BC密封剂。将牙齿安装在细菌渗漏装置上，在粪肠球菌(Enterococcus Faecalis)的十亿蛋白琼脂培养基中于37℃孵育30天。结果:27根(30%)发生龋漏。与Bioroot®(19.7)和TotalFill®(19.5)相比，1组(AH®Plus)泄漏样品的百分比最高(40%)，平均泄漏时间最短(16.9)，但差异不显著(p> 0.05)。结论:在本研究中分析的封口器中没有一个产生有效的根尖封口器，其中没有细菌泄漏发生。总样本的三分之一出现泄漏，但组间差异不显著。
