The aim of this study was to compare the short and long term apical sealing ability of different root canal sealers.
Fifty-five extracted human anterior single-root teeth were used. The coronal part of each tooth was removed and the root canals were prepared with NiTi rotary instruments. Teeth were divided into 5 study groups; Group I: MTA Fillapex (Angelus, Brazil); Group II: Sealapex (Sybron-Kerr, Romulus, MI, USA) and Group III: AH Plus (Dentsply, Konstanz, Germany) (n=15) and negative and positive control groups (n=5). The quality of root canal sealing was assessed by a fluid filtration method performed at 24 h and 180-day time intervals. Kruskal Wallis and Mann Whitney U tests were used to compare the groups.
At 24 h evaluation, MTA Fillapex presented significantly less microleakage than the Sealapex and AH Plus (p<0.05). At long term interval (180-day), Sealapex and AH Plus presented significantly less microleakage than the MTA Fillapex (p<0.05).
Sealapex and AH Plus showed significantly better sealing abilities than MTA Fillapex in the long term.
本研究旨在比较不同根管封闭剂的短期和长期根尖封闭能力。
使用55颗拔除的人类前牙单根牙。去除每颗牙齿的冠部，并用镍钛旋转器械预备根管。牙齿分为5个研究组；第一组：MTA Fillapex（巴西安吉利斯公司）；第二组：Sealapex（美国密歇根州罗穆卢斯市Sybron-Kerr公司）；第三组：AH Plus（德国康斯坦茨市登士柏公司）（n = 15）以及阴性和阳性对照组（n = 5）。通过在24小时和180天时间间隔进行的液体过滤法评估根管封闭质量。使用Kruskal Wallis和Mann Whitney U检验比较各组。
在24小时评估时，MTA Fillapex的微渗漏明显少于Sealapex和AH Plus（p < 0.05）。在长期（180天）时，Sealapex和AH Plus的微渗漏明显少于MTA Fillapex（p < 0.05）。
从长期来看，Sealapex和AH Plus的封闭能力明显优于MTA Fillapex。
