J Dent Res:对牙科用玻璃陶瓷腐蚀的新测试

2017-09-20 lishiting MedSci原创

这篇研究是将玻璃陶瓷材料浸入循环pH溶液中,通过检测溶液中硅元素的释放水平和浸泡过的陶瓷材料表面形态变化来评估循环pH浸没对玻璃陶瓷材料腐蚀的影响。研究推测:循环pH浸没会比恒定pH促使更多的表面降解。

这篇研究是将玻璃陶瓷材料浸入循环pH溶液中,通过检测溶液中硅元素的释放水平和浸泡过的陶瓷材料表面形态变化来评估循环pH浸没对玻璃陶瓷材料腐蚀的影响。研究推测:循环pH浸没会比恒定pH促使更多的表面降解。研究通过电感耦合等离子体原子发射光谱仪检测硅离子浓度,通过扫描电镜检测表面形态变化。另外,研究使用2种不同的pH循环序列(pH 2, 7, 10和pH 10, 2, 7)。将玻璃陶瓷圆盘浸入每种pH溶液中3天,随后循环27天。结果显示,循环pH溶液浸没过程中硅离子的释放水平要明显高于恒定pH溶液中所释放的硅离子水平。2种循环序列产生的硅离子水平约为47,超过恒定pH值分别为2和10条件下硅离子水平的2倍。与恒定pH溶液相比较,循环浸没也会使陶瓷形态明显降解。结论:玻璃陶瓷降解的严重程度不仅依赖于现浸没溶液的pH值,也依赖于之前溶液的pH值。由于口腔环境pH值能够随着日常饮食和唾液缓冲能力的变化而改变,所以通过恒定pH浸没会过低评估材料在体内的侵蚀程度。为此,还需要探索循环pH对玻璃陶瓷腐蚀影响的新机制。原始出处:Esquivel-Upshaw JF, Ren F, et al.
