Resumo

O objetivo do presente artigo é avaliar o efeito do açaí na cor, dureza e rugosidade de uma resina composta nanoparticulada in vitro. As amostras foram distribuídas aleatoriamente em três grupos de acordo com a degradação química (n=25): saliva artificial (controle, pH 7,0) e sorbet de açaí (pH 3,8) e suco de açaí (pH 4,9). Os resultados de cor (escala CIELa*b*), rugosidade (Ra) e dureza de superfície (SH) foram analisados antes e após a degradação. As amostras foram submetidas a 3 imersões diárias (6 ml, 15 minutos) durante 14 dias (37°C). As amostras foram lavadas com água destilada ao final de cada imersão e nos intervalos (30 minutos) permaneceram em saliva fresca. Ao final da terceira imersão, as amostras foram colocadas em saliva fresca e nela permaneceram durante a noite. Os valores de ΔE* foram 1,88 para saliva/ sorbet e 2,2 para suco (p=0,017). Das três soluções, apenas o suco reduziu os valores de L* e aumentou os valores de a* (p<0,001). Não foi observada diferença significativa entre os grupos (p>0,05) para dureza e rugosidade. As propriedades mecânicas da resina composta nanoparticulada não foram alteradas pelo açaí. Assim, não há necessidade de descontinuar o consumo de açaí para pacientes com restaurações de resina composta nanoparticuladas.
