Abstract

Objectives: The aim of this study was to investigate the characterization of composite resin inlay surface with silane and non-thermal atmospheric pressure plasma treatment. Methods: Composite resin inlay was used as a specimen, which was treated by sandblasting + silane and sandblasting + plasma. The untreated specimens were assigned to the control group. Specimens were analyzed for surface roughness, color change, and chemical composition. Statistical analyses were performed using one-way ANOVA test (p<0.05). Results: The present findings showed that the roughness and color changes of the plasma-treated surface were significantly lower than those of the silane-treated surface. In addition, a change in the chemical composition was observed on the plasma-treated surface. Conclusions: Based on the results, non-thermal atmospheric pressure plasma could be a potential tool for the cementation of composite resin inlay.
