“…The fluorescence emission spectra showed similar peak tendency (i.e. ±450 nm) as some earlier studies 15,21,22,26,36) . However, it was not possible to correlate the results of the present study with the results of previous ones, since the aims and as consequence the applied methods differ.…”

“…The qualities of the device allowed the fast and sensitive measurement of the vast number of analyzed samples in the present study. According to the literature, there is some evidence 22,40) that fluorescence properties of resin composites significantly change when the material ages 28,41,42) . Therefore, fluorescence measurements in the presented study method were done after standardized storage time and at constant temperature.…”

The objective was to assess the fluorescence properties of current commercial resin composites. Sixteen light-curing resin composites, representing a total number of 241 shades, were analyzed. Fluorescence measurements of all samples were taken using the monochromator-based fluorescence reader Synergy TM Mx (BioTek Instruments Inc.). Additionally, samples of dentin and enamel were analyzed for comparison. The mean of the maximum excitation wavelength was (398±5) nm and the mean of the resulting emission wavelength was (452±9) nm for all composite shades. The maximum fluorescence varied widely between 50 and 70,808 RFU with a mean of (28,948±15,380) RFU. The maximum for dentin was (9,308±3,676) RFU and enamel (5,467±506) RFU. The results showed that the analyzed composites fluoresced at nearly the same excitation-emission wavelengths combination but with varying optical intensities. These results provide useful reference for optimal fluorescence induction and may help to develop better fluorescence diagnostic methods needed for treatment, forensic investigations and epidemiological research/analyses.

“…Differences in fluorescence intensities between composites already are described in previous analyses [6][7][8][9]21,25) . However, none of them depicted the individual maximum fluorescence intensity properties attainable for the different composite shades masses of several different brands.…”

“…In recent years, the manufacturers of composites have been advertising their products possessing natural tooth-like fluorescence properties. Nevertheless, the fluorescent behavior of composites still does not seem identical to that of natural teeth [7][8][9][10] . Sound teeth generate maximum visible fluorescence emission in the blue-violet spectrum by an excitation wavelength of ultraviolet (UV) or near UV-light of approximately 400 nm.…”

The aim of this study was to determine singular fluorescence qualities of different, commercially available resin composites shades. A total of 234 brand name colors including enamel, dentin and special shades were examined using a monochromator-based spectrophotometer. From the examined composites, Filtek TM Z250 (867±279) RFU and Supreme XT (dentin shades: (1,585±507) RFU; enamel shades: (4,473±330) RFU) are the only brands with a mean fluorescence maximum that resembles the fluorescence of natural samples. The shade types of the other brands showed a three to fifteen times higher mean maximum fluorescence (dentin shades: (10,331-47,774) RFU; enamel shades: (19,264) RFU; special shades: (35,934-60,001) RFU). The results of the present study supply for the first time individual fluorescence qualities of a vast sample of different composite shades, data needed not only for the development of new materials, but for diagnostic reasons in routine (re-)treatment, forensic and epidemiological endeavors.

“…7 Although explored as marketing proposal, previous studies show that fluorescence is one of the optical properties affecting only subtly the visual perception and appearance. 8,9 Fluorescence can be influenced by the diet (food, drinks, and smoke) and oral hygiene habits (mouthrinses). According to the World Health Organization, about one billion people around world smoke, since adolescence in most cases.…”

Introduction: This study evaluated the fluorescence intensity (FI) of different brands of composite resins (CRs) and compare those values with the FI of human tooth, under the action of cigarette smoke (CI), coffee (CA), and soft drink (CO), measured by direct spectrometry. Materials and methods:A total of 30 specimens of each brand (Filtek Z350, Esthet-X, Amelogen, Durafill) were made. Others 30 tooth specimens (3 mm/diameter) were obtained from human molars using a trephine bur. The specimens were randomly divided into three groups (n = 10), according to substances: CI, CA, CO. The FI was directly measured using an optic fiber associated with a spectrometer and was measured at baseline and after staining. Data were submitted to Kruskal-Wallis, Dunnett, and Dunn tests. Results:Staining influenced FI mean values among CRs and between those with human tooth. Z showed the closest FI mean values of tooth after staining. Conclusion:Staining beverages and cigarette smoke negatively influenced on FI of CR and human tooth.Clinical significance: The study shows darkening treatments influenced on the fluorescent property of the dental tissues and restorative materials according to the direct spectrometry analysis.
