The long-term preservation of fluorescence qualities of resin-based composite (RBC) restorations is an absolute condition for the implementation of the fluorescence-aided identification technique (FIT) in dentistry and forensic medicine. Therefore, this study assessed the fluorescence of 244 color shades of 16 commercially available RBC brands with a monochromator-based multimode microplate reader. The specimens were stored in the dark at room temperature and reassessed ten years after the initial investigation. The mean intensity of the fluorescence maxima decreased from (31,030±936) RFU to (22,027±632) RFU. Linear regression resulted in r=0.972 and a slope=0.701±0.005. The fluorescence intensity of the tested RBCs dropped to about 70% of the initial intensity independent of the brand, color shade and initial fluorescence intensity. On the basis of this in vitro 10-year data set, we assume that in vivo RBC fluorescence is also suitable for the detection and differentiation of clinically aged RBC restorations by FIT.
树脂基复合材料（RBC）修复体荧光特性的长期保持是在牙科和法医学中实施荧光辅助识别技术（FIT）的绝对条件。因此，本研究使用基于单色仪的多模式微孔板读数器评估了 16 种市售 RBC 品牌的 244 种颜色的荧光。将标本在黑暗中于室温下储存，并在初始研究十年后重新评估。荧光最大值的平均强度从（31,030±936）RFU 降低到（22,027±632）RFU。线性回归得到 r=0.972 和斜率=0.701±0.005。无论品牌、颜色和初始荧光强度如何，测试的 RBC 的荧光强度下降到初始强度的约 70%。基于该体外 10 年数据集，我们假设体内 RBC 荧光也适用于 FIT 检测和区分临床老化的 RBC 修复体。
