ABSTRACT

PURPOSE: In this case report, the clinical performance of a microhybrid resin composite placed with or without a flowable resin composite was compared, over a 48-month period.
CASE DESCRIPTION: The patient of this case report presented 2 pairs of equivalent cervical abfraction lesions, under occlusion. Four restorations were placed in teeth 34, 35, 44 and 45. The restorations were divided into groups (Single Bond + Filtek-Flow + Filtek Z250 or Single Bond + Filtek Z250) and the materials were applied according to the manufactures instructions. Two previously calibrated operators placed the restorations and two other independent examiners evaluated the restorations at baseline and after 48 months, according to the USPHS criteria and modified criteria for color match.
CONCLUSION: After 48 months of evaluation the lesions restored with Filtek-Flow as a liner under Filtek Z250 did not show better clinical performance than the restorations without Filtek-Flow. All restorations showed a trend toward dark yellowing after 48 months.

Key words: Clinical evaluation; adhesive systems; composite resin; flowable composite


RESUMO

OBJETIVO: Este relato de caso compara o desempenho clínico após 48 meses de restaurações de lesões cervicais não cariosas com uma resina composta microhíbrida associada ou não a uma camada de resina flow como um agente intermediário.
DESCRIÇÃO DO CASO: O paciente do presente caso apresentava 2 pares de lesões cervicais não cariosas ocasionadas por abfração sob oclusão. Nos elementos dentários 35 e 44 as restaurações foram feitas com Single Bond + Filtek-Flow + Filtek Z250 e nos elementos 45 e 34 com Single Bond + Filtek Z250, sendo os materiais empregados de acordo com as recomendações do fabricante. Dois operadores previamente calibrados colocaram as restaurações e dois outros examinadores avaliaram as restaurações no período imediato (baseline) e após 48 meses, de acordo os critérios USPHS modificado para o critério cor.
CONCLUSÃO: Após 48 meses as lesões restauradas com a resina flow como uma camada intermediária não demonstraram melhor desempenho clínico em relação às restaurações sem a resina flow. Todos os grupos apresentaram uma tendência à descoloração após 48 meses de acompanhamento clínico.
