The detection and removal of tooth-colored filling materials is a major challenge for every dentist. The Fluorescence-aided Identification Technique (FIT) is a noninvasive tool to facilitate the distinction of composite resin material from sound tooth substance. Compared to conventional illumination, FIT is a very accurate, reliable, and fast diagnostic method. When composite resin is illuminated with a wavelength of approximately 398 ± 5 nm, certain fluorescent components make the composite resin appear brighter than the tooth structure. Any fluorescence-inducing light source with the appropriate wavelength can be used for this method. Optimally, this technique is used without additional natural or artificial lighting. The application of FIT can be used for diagnostic purposes, for example, dental charts, and additionally for the complete and minimally invasive removal of composite resin restorations, bracket debonding, and trauma splint removal. The assessment of volumetric changes after composite removal can be provided by overlapping pre- and postoperative scans and subsequent calculation using suitable software.
检测和去除牙色填充材料是每个牙医面临的主要挑战。荧光辅助识别技术 (FIT) 是一种非侵入性工具，可帮助区分复合树脂材料和健康的牙齿组织。与传统照明相比，FIT 是一种非常准确、可靠和快速的诊断方法。当复合树脂材料受到约 398 ± 5nm 波长的光照射时，某些荧光成分会使复合树脂比牙齿结构更亮。任何具有适当波长的荧光诱导光源都可用于该方法。在理想情况下，此技术在没有额外自然光或人工照明的情况下使用。FIT 的应用可用于诊断目的，例如，牙图，以及完全和微创地去除复合树脂修复体、托槽去粘接和创伤夹板去除。通过重叠术前和术后扫描并使用合适的软件进行后续计算，可以提供复合树脂去除后体积变化的评估。
