Graphene oxide (GO) coatings have emerged as a promising method to enhance materials' surface properties and mechanical performance. In the context of endodontic files, the efficacy of these instruments is critically dependent on the properties of their outermost layer. Surface treatments and coatings can substantially improve these characteristics. GO has been utilized to create nanocomposite coatings to enhance files' surface attributes and mechanical performance.
This research aimed to study the elemental analysis of a nickel-titanium (Ni-Ti) pediatric rotary file coated with GO using energy dispersive X-ray (EDX) analysis.
This study used Ni-Ti pediatric rotary files, each 16 mm in length and with an International Organisation for Standardisation (ISO) tip size of #25. Before coating, the existing titanium oxide layer on the files was removed. The GO coating was then applied via electrophoretic deposition (EPD). The chemical composition of the GO-coated endodontic files was analyzed through EDX spectroscopy, and the results were represented in graphical form to evaluate the effectiveness of the coating.
Elemental analysis revealed a significant increase in the weight percentage of carbon (C) across most of the GO-coated files. In contrast, oxygen (O) was more prevalent at the tip and cutting edge, with its weight percentage decreasing along the shaft. These findings indicate the successful deposition of GO on the external surfaces of the coated endodontic files.
GO coatings were effectively applied to Ni-Ti endodontic instruments using EPD. EDX analysis verified uniform deposition of the GO coating across the surface of the Ni-Ti rotary instruments.
氧化石墨烯（GO）涂层已成为一种增强材料表面性能和机械性能的有前景的方法。在根管锉的背景下，这些器械的功效关键取决于其最外层的性能。表面处理和涂层可大幅改善这些特性。GO已被用于制备纳米复合涂层，以增强锉的表面属性和机械性能。
本研究旨在使用能量色散X射线（EDX）分析对涂有GO的镍钛（Ni-Ti）儿童旋转根管锉进行元素分析。
本研究使用Ni-Ti儿童旋转根管锉，每根长度为16 mm，国际标准化组织（ISO）尖端尺寸为#25。在涂层之前，去除锉上现有的氧化钛层。然后通过电泳沉积（EPD）施加GO涂层。通过EDX光谱分析涂有GO的根管锉的化学成分，并以图形形式呈现结果，以评估涂层的有效性。
元素分析显示，大多数涂有GO的锉上碳（C）的重量百分比显著增加。相比之下，氧（O）在尖端和切削刃处更为普遍，其重量百分比沿杆部递减。这些发现表明GO成功沉积在涂覆的根管锉的外表面上。
使用EPD将GO涂层有效地应用于Ni-Ti根管器械。EDX分析证实了GO涂层在Ni-Ti旋转器械表面的均匀沉积。
