“…7 There have been reports that fluorescence can be used as a tool to identify a dental restorative material, distinguish it from natural tooth tissue, and allow it to be examined after staining. 28,47,48 Differentiation of resin composite restorations from teeth using fluorescent emission was investigated as basic research for the visual detection of resin-filled teeth in mass dental health examinations. 49 For this, fluorescence spectra were taken from extracted human maxillary central incisors and 12 types of resin composites via excitation using light with wavelengths of 400 to 500 nm (400, 430, 450, and 470 nm).…”

“…Differentiation of porcelain from tooth using fluorescent emission was investigated for the visual detection of porcelain-restored teeth in mass dental health examinations. 47 The fluorescence spectra were taken from the extracted human maxillary central incisors and five types of porcelain by excitation using light of 380 to 470 nm. As a result, there was a clear difference in fluorescence intensity between tooth and porcelain using excitations longer than 400 nm.…”

Abstract. Fluorescent emission of human teeth and dental calculus is important for the esthetic rehabilitation of teeth, diagnosis of dental caries, and detection of dental calculus. The purposes of this review were to summarize the fluorescence and phosphorescence of human teeth by ambient ultraviolet (UV) light, to investigate the clinically relevant fluorescence measurement methods in dentistry, and to review the fluorescence of teeth and dental calculus by specific wavelength light. Dentine was three times more phosphorescent than enamel. When exposed to light sources containing UV components, the fluorescence of human teeth gives them the quality of vitality, and fluorescent emission with a peak of 440 nm is observed. Esthetic restorative materials should have fluorescence properties similar to those of natural teeth. Based on the fluorescence of teeth and restorative materials as determined with a spectrophotometer, a fluorescence parameter was defined. As to the fluorescence spectra by a specific wavelength, varied wavelengths were investigated for clinical applications, and several methods for the diagnosis of dental caries and the detection of dental calculus were developed. Since fluorescent properties of dental hard tissues have been used and would be expanded in diverse fields of clinical practice, these properties should be investigated further, embracing newly developed optical techniques.

Controlled fluorescence in a beetle's photonic structure and its sensitivity to environmentally induced changes

et al. 2016

The scales covering the elytra of the male Hoplia coerulea beetle contain fluorophores embedded within a porous photonic structure. The photonic structure controls both insect colour (reflected light) and fluorescence emission. Herein, the effects of water-induced changes on the fluorescence emission from the beetle were investigated. The fluorescence emission peak wavelength was observed to blue-shift on water immersion of the elytra whereas its reflectance peak wavelength was observed to red-shift. Time-resolved fluorescence measurements, together with optical simulations, confirmed that the radiative emission is controlled by a naturally engineered photonic bandgap while the elytra are in the dry state, whereas non-radiative relaxation pathways dominate the emission response of wet elytra.

In recent dental care, esthetic restorative materials such as composite resin and porcelains have been widely used and studied. However, their good esthetics makes the visual inspection of restored teeth difficult. In this study, a fluorescent glass filler containing rare earth oxides, which are well-known fluorescent materials, was prepared and used in composite resin to add visual inspection ability with small change in color.
