The Benefits of Fluorescent Stain

Although most internal stains claim to be fluorescent, the use of an ultraviolet/"black" light will show you which ones truly are and which have the highest levels of fluorescence (Figure 1). Mixing a small amount of fluorescent stain into the opacious dentin (5% to 10 % stain) allows technicians the ability to manipulate the wave of light. This newly mixed material has the ability to reflect, refract, and absorb light in small spaces as natural teeth do. This is the material of choice when lengthening a tooth with minimal space (Figure 2 and Figure 3). This opaque yet fluorescent mix is used to extend the preparation length and can seem very thin from an incisal view (Figure 4 and Figure 5). Normal build-up can begin once the material mix is placed and the optics have been managed (Figure 6). When the restorations are complete, backlighting shows us that no transition line is present and that the reconstructed tooth reacts to light like a natural tooth would. (Figure 7 and Figure 8). Although the cast pictures are helpful in order to see the light and effect, in the end what always matters the most is the ability of our materials to harmonize within the mouth (Figure 9 and Figure 10). Fluorescent stains have many abilities to aid in the final esthetics of our work, but they are critical when extending from either a substructure or a natural tooth. Consider how to improve the esthetics of your case with a small amount of fluorescent material. A little bit of light manipulation goes a long way.
