Resumo
Objetivo: Avaliar a influência da higienização com diferentes pastilhas de limpeza na rugosidade superficial de placas oclusais confeccionadas em PMMA por impressão CAD/CAM aditiva, discutindo as possíveis implicações para a durabilidade clínica. Métodos: Foram confeccionadas cinquenta amostras (N=50) medindo 2X2 cm em polimetilmetacrilato (PMMA) a partir do processo de impressão CAD/CAM aditivo, sendo divididas em Grupo Controle (GC), Corega Tabs 3 minutos (G1), Corega Tabs Branqueador (G2), Efferdent (G3) e Kin Oro (G4), com dez amostras para cada grupo. Foi feita a simulação de 6 meses de uso, de acordo com o tempo de ação de cada pastilha de limpeza. Resultados: Foi utilizado o teste de normalidade de Kolmogorov-Smirnov e, posteriormente, o teste de Kruskal-Wallis. Não houve alterações significativas na rugosidade das placas oclusais após a higienização com as pastilhas de limpeza (p>0,05 em todas as medidas). Conclusão: O uso das pastilhas de limpeza como forma de higienização não causa mudanças significativas na rugosidade superficial das placas feitas de PMMA, sugerindo boa compatibilidade do material nas condições laboratoriais avaliadas.
