“…Studies have revealed that most of the restorative composite resins and the natural tooth enamel exhibited the similar color of the fluorescence (Kim et al, 2016;Lopes et al, 2021). A recent study reported that the fluorescence intensity of Filtek Z350 XT under ultraviolet was even weaker than natural tooth enamel (Lopes et al, 2021). The strong yellowish fluorescence of FAR and AFAR-2 could help the professional to identify the resin and the enamel with the assistance of an ultraviolet radiator.…”

“…Besides this, the precise composition of these materials is proprietary information, therefore, it is particularly hard to define which component is responsible for the fluorescent effect. In the international scientific literature, we found only comparative studies between different material brands or studies that compare natural teeth with restorative materials [4,5,10,11].…”

Currently available direct restoration materials have been developed to have improved optical properties to interact with light in the same manner as the natural tooth. The objective of this study was to investigate the fluorescence of different enamel resin composites. In the present study, nine brands of enamel composites were tested in vitro, some of which are cited by manufacturers as having color adjustment potential. Fluorescence spectra of the composite specimens and the human natural enamel were measured with a fluorescence spectrophotometer immediately after preparation and after 6 months. Qualitative data of the specimens were also collected. Statistical analyses were conducted by Kruskal–Wallis and Mann–Whitney U nonparametric tests (p < 0.05). Almost all tested resin composites presented a significant decrease in the fluorescence values after a period of 6 months. There was no significant decrease in fluorescence in the case of Harmonize™ resin composite samples, which presented the lowest initial fluorescence values. The highest value in the reduction of the initial fluorescence intensity after 6 months (22.95%) was observed for the Charisma® specimens. Composites with a color adjustment did not perform significantly better than other composites in terms of reduction in fluorescence intensity.

O propósito deste estudo foi avaliar nove resinas compostas de diferentes opacidades através de espectrofotometria e fluorescência, que passaram a compor os seguintes grupos (n=3): P4 (Point 4 XL1 - Kerr); M3 (Enamel Plus HRi UE3 - Micerium); BF (Filtek™ One Bulk Fill A2 - 3M); FB (Filtek™ Universal B2 - 3M ESPE); FA (Filtek™ Universal A2 - 3M); V1 (Vittra APS A2 - FGM); Z1 (Filtek™ Z350 XT A2E - 3M); Z2 (Filtek™ Z350 XT A2B - 3M); O2 (Opallis A2D - FGM). Os blocos de resina foram confeccionados e submetidos à leitura por espectrofotometria e fluorescência induzida por UV (365 nm). Os dados obtidos foram tabulados nos programas Origin 2018 (Analysis and Graphing Samples). Realizou-se o teste de diagnóstico de normalidade descritivo pelo teste Kolmogorov-Smirnov (p> 0,05) atendendo ao pré-requisito dessa distribuição, além de terem sido comparados pelo teste t de Student, com um nível de confiança de 95% (p <0,05) quando nas análises 2 a 2 e pela ANOVA e teste de Tukey, na comparação de 3 ou mais grupos. Nos resultados da análise espectrofotométrica foram constatadas diferenças significativas entre os grupos (p <0,01). As resinas avaliadas apresentaram altos índices de fluorescência na cor azul, com diferenças significativas entre os grupos (p=0,01). O grupo M3 foi considerado o mais luminoso por ter excelente reflexão e fluorescência em azul e nenhuma na cor vermelha. Resinas de esmalte cromático com altos valores de luminosidade e fluorescência possibilitam a reprodução de forma mais fidedigna das características óticas dos dentes naturais.
