(P 0.05). The packable composite -with or without fluid composite- showed lower microleakage, whereas microhybrid and fiber-reinforced composites without fluid composite, showed higher mi-croleakage. Discussion: The fluid composite significantly decreased the microleakage at gingival margins of Class II composite restorations.
