科学领域:

材料科学材料科学材料科学
分析化学分析化学
牙科材料牙科材料

背景情况:

双A (BPA) 是一种化学化合物,用于各种塑料和树脂材料.
人们对BPA从牙科材料出口腔环境存在担忧.
计算机辅助设计/计算机辅助制造 (CAD/CAM) 越来越多地用于制造牙.

研究的目的:

量化和比较四种不同的CAD/CAM splint材料中的双甲 (BPA) 释放.
评估这些材料中的 BPA 化是否超过已确定的安全值.

主要方法:

测试了四种CAD/CAM线材料 (3种基于聚碳酸盐,1种基于聚甲基甲酸盐).
圆柱形样本被浸入HPLC级水中,并在37°C进行24小时的化.
使用高性能液体染色学-并联质谱法 (HPLC-MS/MS) 分析了BPA度.

主要成果:

所有经过测试的CAD/CAM片材料都释放出大量的BPA.
BPA化因材料而异,聚碳酸基材料的释放率高于聚甲基甲酸基材料的释放率.
计算出的每支 splint 体积的 BPA 度超过了欧盟可容忍每日摄入量 (TDI) 的 1.32 到 6.16 倍.

结论:

在牙科实践中,CAD/CAM线材料可能是BPA暴露的重要来源.
高水平的BPA化要求对材料安全性和潜在的健康影响进行进一步调查.
材料选择和临床处理可能会影响CAD/CAM片中的BPA释放.
