This study aimed to observe the effects of high temperature on different restorative dental materials by detecting changes in their microstructural and elemental composition. Disk shaped samples (10 mm diameter, 2 mm depth) were prepared from 8 dental materials (compomer, glass carbomer, ormocer, giomer, zinc reinforced glass ionomer (GI), silver-alloy reinforced GI, zirconia reinforced GI, and conventional GI). Scanning electron microscopy/Energy dispersive X-ray spectroscopy (SEM/EDS) was used to characterize sample surface structures and elemental composition. The same samples were also analyzed using X-ray fluorescence (XRF) to determine the trace element content. Each sample was placed in a porcelain furnace and exposed to 900 °C for 30 min. Observations of macroscopic changes in samples after exposure high temperature were recorded. The microstructural changes in sample surfaces after incineration were detected by SEM. The elemental compositions obtained before and after the incineration were compared after repeating the XRF and EDS analyses. Dental materials demonstrated specific macroscopic changes and microstructural deteriorations detected by SEM images after exposure to high temperature. While several changes occurred in the elemental content of materials in terms of amount, the original elemental composition was preserved. The ability to distinguish dental materials by elemental analyses has had an important impact on the identification process.

本研究旨在通过检测不同修复牙科材料的微观结构和元素组成的变化，观察高温对不同修复牙科材料的影响。由 8 种牙科材料（复合体、玻璃卡波姆、ormocer、焦聚体、锌增强玻璃离聚物 (GI)、银合金增强 GI、氧化锆增强 GI 和常规 GI）制备圆盘形样品（直径 10 毫米，深度 2 毫米） . 扫描电子显微镜/能量色散 X 射线光谱 (SEM/EDS) 用于表征样品表面结构和元素组成。还使用 X 射线荧光 (XRF) 分析了相同的样品以确定痕量元素含量。将每个样品置于瓷炉中并在 900°C 下暴露 30 分钟。记录样品在暴露于高温后的宏观变化。通过扫描电镜检测焚烧后样品表面的微观结构变化。在重复 XRF 和 EDS 分析后，比较了焚烧前后获得的元素组成。牙科材料在暴露于高温后显示出特定的宏观变化和 SEM 图像检测到的微观结构退化。虽然材料的元素含量在数量方面发生了一些变化，但原始元素组成得以保留。通过元素分析区分牙科材料的能力对识别过程产生了重要影响。牙科材料在暴露于高温后显示出特定的宏观变化和 SEM 图像检测到的微观结构退化。虽然材料的元素含量在数量方面发生了一些变化，但原始元素组成得以保留。通过元素分析区分牙科材料的能力对识别过程产生了重要影响。牙科材料在暴露于高温后显示出特定的宏观变化和 SEM 图像检测到的微观结构退化。虽然材料的元素含量在数量方面发生了一些变化，但原始元素组成得以保留。通过元素分析区分牙科材料的能力对识别过程产生了重要影响。
