The effects of mechanical and chemical degradation on the surface roughness, gloss, and color stability of bulk-fill resin composites.

ABSTRACT:

Background

The aim of this study was to evaluate the effects of different pH solutions and brushing on the surface roughness, color stability and surface gloss of different bulk-fill resin composites.

Methods

Ten disc-shaped specimens were prepared from each resin composite (Filtek Bulk-Fill, Estelite Bulk-Fill Flow, Tetric N-Ceram Bulk-Fill, Opus Bulk-Fill, Admira Fusion X-tra, Beautifil Bulk). After measuring the initial surface roughness, color, and gloss values of the prepared specimens, each group were immersed in the following solutions for seven days: hydrochloric acid solution, cola, and coffee. Afterwards, specimens were subjected to simulated tooth brushing and then surface roughness, color, and gloss values were measured again. The data were analyzed using the One
