Objetivo: O objetivo deste estudo laboratorial foi diferenciar a cor da dentina natural (ND) e da porcelana dentinária (DP) usando três marcas de Glass-Matrix Ceramic System (GMCS) pelo sistema paramétrico CIE L*, a*, b* . Materiais e métodos: Um incisivo central superior humano extraído foi preparado como grupo controle. Amostras de dentina uniformemente espessas foram retiradas do terço coronal médio da metade labial longitudinalmente. Doze discos de porcelana de dentina GMCS foram fabricados de acordo com as instruções do fabricante usando a técnica convencional de pó/pasta, 4 discos para cada grupo; Cerâmica feldspática VITA VMK 95 (VMK), cerâmica à base de leucita VITA VM9 (VM9) e cerâmica à base de fluorapatita IPS e.max Ceram IVOCLAR (IEC). As espessuras dos corpos de prova ND e DP foram (8×1 mm, cor A3) e (n=4). Uma câmera digital foi usada para tirar fotos das amostras enquanto as leituras de cores foram obtidas por software gráfico. As cores dos espécimes foram medidas e os dados foram avaliados estatisticamente usando o teste de Levene, One-way ANOVA e Post Hoc Multiple Comparisons. Resultados: Os valores paramétricos CIE L*, a*, b* e ΔE de todos os discos cerâmicos em comparação com ND foram significativamente diferentes mesmo dentro das marcas de cerâmica (P<0,05), ΔE foram ND > IEC > VMK > VM9. Conclusões: Para reproduzir a cor ND por DP, é necessário selecionar a escala de cores adequada devido às diferenças de cor de uma marca para outra, mesmo na mesma guia de escala de cores. Significado Clínico: Há uma falta de informação sobre como a cor de dentina natural é idêntica à da porcelana de dentina na mesma escala de cores.
