OBJECTIVE
The aim of this study was to evaluate the flow rate of 3 endodontic sealers: Sealer 26, AH Plus, and MTA Obtura.
STUDY DESIGN
According to the method proposed by the American Dental Association (ADA specification no. 57), the sealers were placed between 2 glass slabs under a weight of 120 g. The diameters of the formed discs were measured with a digital paquimeter. The test was repeated 5 times for each sealer.
RESULTS
The results were expressed as arithmetic means, and the statistical analysis was performed through Turkey test. AH Plus showed significantly superior flow rate compared with Sealer 26 and MTA Obtura. There was no statistically significant difference between flow rates presented by Sealer 26 and MTA Obtura.
CONCLUSION
Within the limitations of this in vitro study, it was concluded that all of the the endodontic sealers tested presented greater flow than the minimum recommended in the ADA 57 specification.
目的
本研究旨在评估三种根管封闭剂的流动速率：Sealer 26、AH Plus和MTA Obtura。
研究设计
根据美国牙科协会提出的方法（ADA规范第57号），将封闭剂置于两块玻璃板之间，施加120克重量。用数字测径仪测量形成圆盘的直径。每种封闭剂重复测试5次。
结果
结果以算术平均值表示，并通过土耳其检验进行统计分析。与Sealer 26和MTA Obtura相比，AH Plus显示出明显更高的流动速率。Sealer 26和MTA Obtura的流动速率之间没有统计学上的显著差异。
结论
在本体外研究的局限性内，得出的结论是，所有测试的根管封闭剂的流动速率均高于ADA 57规范中建议的最小值。
