“…The examination of sections of enamel confirmed the findings of Dickson et al (1952), as tufts, lamellae and spindles all had a high intensity of fluorescence, thus demonstrating either a high level of fluorescent protein or a low degree of mineralization, or both. The readily observed Hunter-Schreger bands were an unexpected finding, as these are formed by variations in the course of adjacent groups of prisms and do not exhibit variations in composition.…”

“…The first major investigation ofthe fluorescent microstructure of human teeth was by Dickson et al (1952) when they used a photomicrographic camera and a mercury vapour lamp. They observed that dentine was more fluorescent than enamel, and that a particularly intense fluorescence was shown by dentinal tubules and enamel lamellae and tufts.…”

“…21 As to the endogenous fluorophores in enamel and dentine, early investigations of teeth using UV excitation indicated that the light emission was from the organic matrix embedded in the inorganic calcium apatite matrix. 2,6,[22][23][24] It was also reported that the compounds causing fluorescence in human teeth were mostly organic in nature, possibly proteins, as well as the inorganic matrix. [25][26][27] It was confirmed that fluorometric data obtained from basic hydrolysates of dentine protein were identical to those of tryptophan and tyrosine.…”

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.

“…13 Generally, teeth display a bluish-white color under UV light. 5,18,19 The fluorescence spectrum of natural enamel exhibits maximum luminescence peaks at 450 nm, while the dentin shows peaks at 440 nm. 20 The presence of fluorescence in natural teeth has been reported in the literature.…”

“…The first evidence of the presence of fluorescence in natural teeth dates to the 1920s and 1950s, [3][4][5][6][7] and, since then, much of what is known about fluorescence still refers to those studies. A literature review of this topic could compile important information for the reader and reinforce the need for a deeper understanding of this phenomenon, to understand how it influences the perception of aesthetic restorations.…”

Objective This review integrates published scientific information about the fluorescence of natural teeth, dental resins and ceramics, and the main methods of analysis and quantification presented in the literature. Overview Fluorescence is an emission of light (photons) by a substance that has absorbed light of higher energy. In natural teeth, it is more intense in the dentin than in the enamel and presents a bluish‐white color. In dental resins and ceramics, fluorescence is obtained by the incorporation of materials that contain rare‐earth luminescence centers (more precisely lanthanide luminescence centers), which allows these artificial materials to simulate natural teeth in a more beautiful and vital‐looking way. However, the lack of knowledge about this optical phenomenon on the part of professionals indicates the need for more scientific studies and dissemination on this topic. Conclusions Aesthetic materials have variable spectral compositions and fluorescence intensities, which are not always compatible with natural teeth. The fluorescence of teeth and restorative materials can be influenced by several factors, such as aging, temperature, and bleaching. Several devices for fluorescence evaluation and quantification are used in studies under different methodologies, but the small number of studies on the subject make it difficult to compare their results. Clinical Significance Fluorescence is a fundamental optical property for aesthetic rehabilitations since its presence and intensity in the restorative materials allows achieving an aesthetic result much closer to reality. However, the fluorescent behavior of natural teeth and aesthetic restorative materials is not yet fully understood by researchers and clinicians. Greater understanding of this phenomenon will contribute to the selection, indication, and clinical use of these materials.
