Abstract

The aim of this study was to analyses the surface chemistry of different materials used as retrograde filling and compare it with bulk chemical analyses reported. Surface analysis carried out using an X—ray Photoelectron Spectrometer (XPS) built by VG Scientific. Samples of HAP, GIC and Amalgam materials used were prepared as Discs of 10 mm diameter. These transferred on to XPS aluminum stubs. XPS spectra were obtained from the wide scan spectrum of amalgam, the following elements are present: tin (23.2%); mercury (6.6%); carbon (19%) and oxygen (51.2%). The wide scan spectrum of GIC the elements present in the surface of the material are: oxygen (41.1%); aluminum (5%); silicon (4.6%); carbon (36.1%); calcium (11.3%); fluorine (2.1%) and sodium (0.T). The XPS spectra were obtained from the wide scan spectrum of Hydroxyapatite the elements present in the surface are: Oxygen (49-4%), Carbon (33-9%), calcium (8-6%), and Phosphorus (8-4%). In conclusion, the chemical XPS analyses of the materials used as retrograde filling, have shown them to vary considerably with respect to bulk chemical composition. Further surface analysis could include narrow scans, manipulation of surface chemistry, coupled with in vitro and in vivo tests and experiments to determine the importance of different surface components on biocompatibility.
牙科逆行充填材料羟基磷灰石与玻璃离子、银汞合金的表面化学分析
本研究的目的是分析不同材料的表面化学成分作为逆行填充,并比较其与散装化学分析报告。表面分析使用VG科学公司制造的x射线光电子光谱仪(XPS)进行。将HAP、GIC和Amalgam材料制成直径为10 mm的圆盘。这些转移到XPS铝存根上。对银汞合金的宽扫描谱图进行XPS分析,发现存在以下元素:锡(23.2%);汞(6.6%);碳(19%)和氧(51.2%)。GIC的宽扫描谱显示材料表面存在的元素有:氧(41.1%);铝(5%);硅(4.6%);碳(36.1%);钙(11.3%);氟(2.1%)和钠(0.T)。从羟基磷灰石的宽扫描光谱中获得XPS光谱,其表面存在的元素为:氧(49-4%)、碳(33-9%)、钙(8-6%)和磷(8-4%)。总之,化学XPS分析的材料用作逆行填充物,已经表明他们有相当大的变化相对于散装化学成分。进一步的表面分析可包括窄范围扫描、表面化学操作,以及体外和体内测试和实验,以确定不同表面成分对生物相容性的重要性。
