Resumo

Objetivo: Este estudo avaliou a rugosidade superficial (Ra) e a diferença de cor (∆E00) de um compósito de resina composta cor de gengiva (NT Premium Gengiva, Coltene), fotopolimerizável com três unidades fotopolimerizáveis (UFP) e imersa em diferentes soluções de enxaguantes. Métodos: Ao todo, 90 espécimes de compósitos (n=10) foram divididos de acordo com o UFP: L1-Valo, L2-Bluephase e L3-Optilight Max; e solução: S1-enxaguante bucal antisséptico à base de álcool (Listerine Cool Mint), S2-enxaguante bucal antisséptico sem álcool (Listerine Cool Mint Zero Alcohol) e S3-água (controle). As imersões foram realizadas por 30 s, 2×/dia, por 21 dias. Ra e coordenadas de luminosidade (L*) e cor (a* e b*) foram medidas usando um rugosímetro (SJ-201 P/M) e um espectrofotômetro (SP62S), respectivamente, em: T0-início, T1-7 dias, T2-14 dias e T3-21 dias. Resultados: L1 (1,3±0,9) apresentou Ra maior que L3 (0,7±0,6) e L2 (1,0±0,8); e Ra para S2 (0,9±0,1) foi maior do que S3 (-0,1±0,1) e S1 (0,1±0,1). Além disso, L1 (23,3±0,3) apresentou ∆E00 menor que L2 (24,7±0,3) e L3 (25,1±0,3). Conclusão: O Ra do compósito de resina cor de gengiva testado aumentou quando L1 e S2 foram usados, embora os espécimes curados com L1 também tenham apresentado o menor ∆E00.
