The conventional illumination (for example by a dental unit lamp) is an unsatisfactory diagnostic tool for the identification of composite resin restorations. For superior diagnostics with conventional illumination, a magnification aid, drying, or even effortful cleaning of the teeth is necessary. Even under ideal circumstances, conventional illumination seems to be insufficient. A study showed that conventional illumination may lead to misdetection of composite resin restorations and sound tooth substance<sup class="xre...

The application of FIT facilitates the distinction of composite resin materials from sound tooth substance compared to conventional illumination, for example, by a dental unit lamp1,2. Fluorescence occurs when a material emits the light at a higher wavelength than it has been absorbed. As a result of this illumination, the material appears brighter than the tooth3. The maximum fluorescence of composite resin materials occurs when illuminated by a wavelength of 398 &#177; 5 nanometers3. Fluorescence in composite resin materials appears due to rare earth oxides added to the glass fillers, some of the main components of composite resins4,5. The addition of these fluorescent substances intends to adapt the optical properties of composite resins to the tooth structure to improve the esthetic properties of composite resins4,5. FIT is applicable on many composite resin materials as they show these fluorescence properties3. However, fluorescence decreases with the ageing of the composite resin materials6,7,8,9.
The distinguishment of composite resin materials from tooth structure with conventional illumination is a challenge since modern composite resin materials match the optical properties of tooth substance almost perfectly10,11. The misdiagnosis of composite resin results in inaccurate dental charts, false caries risk assessment, and inappropriate treatment planning11. Moreover, epidemiological data is falsified12.
Composite resin is the material of choice for direct restorations due to its straightforward handling, esthetic properties, and clinical performance13. Nevertheless, many composite restorations must be renewed due to secondary caries, fractures, or other reasons14,15. However, the removal of residual composite resin materials can be demanding under conventional light conditions. Even with the application of a magnification aid and the use of tactile probes or extensive drying of the teeth, composite residues are sometimes difficult to distinguish from sound tooth structure. Leftovers of composite remnants during the removal of the adhesive restoration lower the quality of further restorations and have an esthetic impairment due to possible discoloration of the margins1,16,17,18,19,20,21,22. On the contrary, an overpreparation due to misdiagnosis of composite resin versus tooth structure may result in unnecessary substance loss1,2.
In dental traumatology, fixation of the injured teeth using trauma splints is frequent and mandatory in many cases23. The trauma splints are usually fixed on the teeth using a flowable composite resin material. Incomplete removal of the composite resin material in this scenario may lead to the impairments described above. Since dental trauma occurs mostly in front teeth, an impairment of the esthetics and sufficient adhesion of further reconstructions are crucial. Therefore, the aim of the article is to demonstrate the application of the FIT method as an efficient and straightforward approach for detecting and removing composite resin materials.

detection and removal of tooth-colored composite resin using the fluorescence-aided identification technique

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 &plusmn; 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.

Usage of the FIT method makes most composite resin materials appear brighter than sound tooth structure (Figure 2 and Figure 5). Therefore, FIT is applicable not only in the detection of composite resin material, but it also facilitates the removal of composite resin materials in general, and explicitly in posterior teeth, during orthodontic bracket debonding and in trauma splint removal1,2,<s...
