Resumo
Objetivo: Este estudo avaliou a correspondência de cores de compósitos universais, com e sem tonalidade opaca, nas restaurações de dentes anteriores. Material e Métodos: 180 incisivos superiores artificiais, nas cores A1, A3 E A4 receberam reparos de classe III extensos na mesial e distal. As restaurações foram realizadas com compósitos universais de cor única Omnichroma (Tokuyama) e com universais de múltiplas cores Filtek Universal (3M ESPE) e Admira Fusion (Voco), nas tonalidades correspondentes aos dentes. Resinas opacas foram selecionadas para mimetizar a dentina, entre elas: Admira Fusion AO (1,2,3), Omnichroma Blocker e Filtek Z350 XT. Para cada dente, um dos lados foi restaurado com a resina opaca e translúcida, enquanto o outro apenas com a resina translúcida. Os dentes foram fotografados sob a luz artificial gerada por uma lâmpada D56. As cores do remanescente dental e das restaurações foram avaliadas usando o software Adobe Photoshop, obtendo-se os valores de L*, a*, b*. A diferença de cor entre o dente e as restaurações foram calculadas. A análise estatística foi realizada através dos testes ANOVA e Tukey. Resultados: Os resultados da ANOVA mostram diferenças significativas observadas para todos os fatores. Quando todas as cores foram analisadas juntas, Filtek Universal mostrou os melhores resultados. Quando todos foram analisados com a resina opaca, a cor A3 obteve melhor correspondência de cor. Quando todas foram analisadas juntas, o uso da resina opaca resulta em melhor correspondência de cor. Conclusão: Conclui-se que o compósito Filtek Universal mostrou melhores resultados que a resina Admira Fusion, visto que a Admira Fusion demonstrou melhor correspondência comparada a resina Omnichroma. Nenhuma combinação ficou abaixo do limiar de perceptibilidade (PT).
Objective: This study evaluated the color matching of universal composites, with and without opaque shade, in anterior tooth restorations. Material and Methods: 180 artificial upper incisors, in colors A1, A3 AND A4, receive extensive class III mesial and distal repairs. The restorations were carried out with Omnichroma single-color universal composites (Tokuyama) and with Filtek Universal (3M ESPE) and Admira Fusion (Voco) multi-color universal composites, in shades corresponding to the teeth. Opaque resins were selected to mimic dental dentin, including: Admira Fusion AO (1,2,3), Omnichroma Blocker and Filtek Z350 XT. For each tooth, one side was restored with opaque and translucent resin, while the other with only translucent resin. The teeth were photographed under artificial light generated by a D56 lamp. The colors of the remaining teeth and restorations were evaluated using Adobe Photoshop software, obtaining the values of L*, a*, b*. The color difference between the tooth and the restorations were calculated. Statistical analysis was performed using ANOVA and Tukey tests. Results: ANOVA results show significant differences observed for all factors. When all colors were analyzed together, Filtek Universal showed the best results. When all were analyzed with the opaque resin, the color A3 obtained the best color match. When they were all analyzed together, the use of opaque resin resulted in better color matching. Conclusion: It is concluded that the Filtek Universal composite showed better results than the Admira Fusion resin, as Admira Fusion demonstrated better correspondence compared to the Omnichroma resin. No combination was below the perceptibility threshold (PT)
