Surface quality and color stability of posterior composites in acidic beverages.

Context: Consumption of acidic beverages has been reported to alter the physical and esthetic properties of resin composites, which in turn can affect clinical success.

Aims: This study aimed to evaluate the effect of acidic beverages on surface roughness and color stability of Filtek™ Bulk-Fill posterior restorative composite in comparison with Filtek P60 posterior restorative composite.

Settings And Design: Ninety composite discs were used for surface change analysis and another ninety were used for color change analysis.
