Newly available materials for retrograde obturation should have their sealing properties evaluated. The goal of this study was to evaluate the sealing ability of Endo CPM sealer, an MTA-based endodontic cement. Single-rooted extracted human teeth were endodontically treated. After apical sectioning, retrograde cavities were prepared. Teeth were divided into five experimental groups (n=12), in which the following materials were used: Sealer 26 (S26), white Mineral Trioxide Aggregate (MTA), Endo CPM Sealer (CPM1), Endo CPM Sealer in thicker consistency (CPM 2), and zinc oxide and eugenol cement (ZOE), and two control groups (n=3). After retrograde obturation, the teeth were immersed in 0.2% rhodamine B dye for 48 hours in a vacuum chamber Marginal leakage data were subjected to ANOVA and Tukey tests at 5% significance level. S26 presented greater sealing ability (p<0.05) than ZOE, MTA, CPM1, and CPM2, all of which had similar results (p>0.05). We concluded that Sealer 26 has the greatest sealing ability. Endo CPM Sealer, with sealing ability similar to MTA, could be used as a retrograde obturation material.
新出现的用于逆行充填的材料应评估其封闭性能。本研究的目的是评估一种基于MTA的牙髓黏固剂Endo CPM封闭剂的封闭能力。对单根拔除的人牙进行牙髓治疗。根尖切除后，制备逆行窝洞。将牙齿分为五个实验组（n = 12），分别使用以下材料：Sealer 26（S26）、白色三氧化矿物凝聚体（MTA）、Endo CPM封闭剂（CPM1）、稠度更高的Endo CPM封闭剂（CPM 2）以及氧化锌丁香酚水门汀（ZOE），还有两个对照组（n = 3）。逆行充填后，将牙齿置于真空室中，浸泡在0.2%的罗丹明B染料中48小时。边缘渗漏数据采用方差分析和Tukey检验，显著性水平为5%。S26的封闭能力比ZOE、MTA、CPM1和CPM2更强（p<0.05），后四者结果相似（p>0.05）。我们得出结论，Sealer 26具有最强的封闭能力。Endo CPM封闭剂的封闭能力与MTA相似，可作为逆行充填材料使用。
