摘要

本研究的目的是测量三种牙髓密封水泥(AH-Plus、EZ-Fill和AH-26)的甲醛释放量。甲醛释放分析采用高效液相色谱法，可检测低至0.25 ppm。两次运行后，数据被制成表格。AH-Plus根管密封水泥两膏体体系的甲醛释放量最小(0.00039%，3.9 ppm)。其次是EZ-Fill (0.054%， 540 ppm)和AH-26 (0.1347%， 1347 ppm)，其甲醛释放量最大。这两种胶合剂(EZ-Fill和AH-26牙髓充填胶合剂)都是基于粉末-液体混合物。所研究的根管胶合剂(AH-Plus和EZ-Fill)释放的相对微量的甲醛保证了它们作为根管密封胶合剂的使用。

Formaldehyde evaluation from endodontic materials.

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.
