The purpose of this study was to measure the amount of formaldehyde released from three types of endodontic sealing cement (AH-Plus, EZ-Fill, and AH-26). Formaldehyde release was analyzed using High Performance Liquid Chromatography, which could detect as low as 0.25 ppm. The data was tabulated after two runs. The two paste system of AH-Plus endodontic sealing cement had the least amount of formaldehyde release (0.00039%, 3.9 ppm). This was followed by EZ-Fill (0.054%, 540 ppm) endodontic cement and AH-26 (0.1347%, 1347 ppm) endodontic cement which yielded the greatest formaldehyde release. Both of these cements (EZ-Fill and AH-26 endodontic filling cements) are based on a powder-liquid mix. The relative minute amounts of formaldehyde released by the endodontic cements studied (AH-Plus and EZ-Fill) warrant their use as endodontic sealing cements.
本研究的目的是测量三种类型的根管封闭剂（AH-Plus、EZ-Fill和AH-26）释放的甲醛量。使用高效液相色谱法分析甲醛释放量，该方法可检测低至0.25 ppm的甲醛。经过两次测试后将数据制成表格。AH-Plus根管封闭剂的双糊剂系统释放的甲醛量最少（0.00039%，3.9 ppm）。其次是EZ-Fill根管封闭剂（0.054%，540 ppm）和AH-26根管封闭剂（0.1347%，1347 ppm），后者释放的甲醛量最大。这两种封闭剂（EZ-Fill和AH-26根管充填剂）均基于粉液混合。所研究的根管封闭剂（AH-Plus和EZ-Fill）释放的相对微量甲醛证明它们可作为根管封闭剂使用。
