“…However, which fluorescence scale do the manufacturers follow? It seems that CRs are more or less fluorescent according to different manufacturers, 7,8 corroborating the results of this study. Moreover, FI seems to be not related to shade or the characteristics of the resin particles.…”

“…The results showed that the CR Filtek Z350 obtained FI means closest to those of tooth, corroborating previous studies. 8,23 Esthet-X, Amelogen Plus, and Durafill VS showed higher intensity values than those of tooth, as observed by da Silva et al 23 It may be related to differences in fluorophore within the composition of each CR, trade secret not disclosed by the manufacturers. The differences in fluorescence values could be related to the difference in type of particles as well as resin matrix.…”

“…Moreover, FI seems to be not related to shade or the characteristics of the resin particles. 8 One reason for the lack of knowledge on fluorescence is the fact that its measure is not as simple as color-making, performed through using standard color scales and visual method. In general, the fluorescence measurements are made in the laboratory by indirect methods, using spectrofluorometers and bench spectrophotometers from different brands, 7,25 making difficult the study results comparison among FI means and clinical conditions.…”

“…The closer the FI values are of those of the dental tissues and restorative materials, the greater will be the degree of reproducibility of the tooth esthetic characteristics. 7,8 Efforts are made toward understanding the fluorescence property by analyzing tooth structure and CRs. It is known that the FI of the dentin is greater than enamel and is linked to the presence of amino acids, such as tryptophan and hydroxypyridine in its composition.…”

“…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.

The use of tooth-colored composite resin materials in dentistry is increasing. As composite restorations appear similar to the natural tooth structure, their detection is becoming more challenging. The aim of this study was to compare five diagnostic methods for detection of dental restorations and to create reliable postmortem dental records for forensic purposes. A conventional examination method without a direct light source (CONV), with a dental loupe light (DL), Galilean loupes with a direct light source (GDL), a fluorescence-inducing device (FIT), and intraoral radiographs (RX) were compared. Dentists specializing in conservative dentistry or oral surgery and dentistry students participated. Regarding sensitivity, specificity, positive predictive value, and negative predictive value, FIT and RX showed significantly higher results than CONV, DL, and GDL. RX and FIT showed comparable results in identifying composite restorations but depending on their location. The combination of both methods may lead to even better results. In conclusion fluorescence-inducing devices show good results in identifying composite restorations and therefore should be considered as a standard tool in forensic examinations. Another advantage is their small size, low cost, and mobility. Good illumination and magnification devices are recommended to enhance performance during conventional examinations. Involving dentists specialized in conservative dentistry could contribute to dental identification.
