Four endodontic sealers were compared with two series of tests, in thin layer and in 10 mm long and 5 mm diameter rods. Under these conditions, the Pulp Canal Sealer showed the best ability to present a thin layer and the same flow than the Cortisomol. Its setting time was 15 minutes. Forty-eight hours later, the Sealite showed a very good tightness compared to the other sealers. At 30 days, the Pulp Canal Sealer and the OZn-Eugénol were the tightest ones. Less water was absorbed with the Cortisomal and the Sealite. Is there, for these sealers, any correlation between water-absorbtion and tightness?
通过两个系列的测试对四种根管封闭剂进行了比较，测试分别在薄层以及10毫米长、5毫米直径的棒材中进行。在这些条件下，牙髓根管封闭剂呈现薄层的能力最佳，且与Cortisomol具有相同的流动性。其凝固时间为15分钟。48小时后，与其他封闭剂相比，Sealite表现出非常好的密封性。在30天时，牙髓根管封闭剂和氧化锌丁香油酚封闭剂的密封性最佳。Cortisomal和Sealite吸收的水分较少。对于这些封闭剂而言，吸水与密封性之间是否存在任何相关性？
