Objective: The objective of this study was to evaluate the 6-month clinical performance of class I occlusal composite resin restorations through a multicenter, randomized, double-blind, clinical trial. Material e Métodos: Two hundred and eighty class I occlusal restorations were performed in 70 patients (aged between 17 to 50 years).  The restorations were divided into four groups: G1 (Filtek P60/3M ESPE); G2 (Rok/SDI); G3 (Filtek™ P90/3M ESPE); G4 (Evolux/Dentsply). Two pre-calibrated dental practitioners performed and evaluated the restorative procedures regarding to color match, marginal discoloration, recurrent caries, wear (anatomic form) and marginal integrity according to the USPHS criteria. Resultados: In 85.8% of the evaluated restorations was observed the ideal score (A) for color match; 91.4% for marginal discoloration; 100% for recurrent caries; 87.7% for wear (anatomic form) and 99.3% for marginal integrity. Conclusion: The composite resins used in this study presented satisfactory and similar clinical performance in a 6-month clinical evaluation.
