The effect of prophylaxis paste and air-powder polishing on color stability and surface roughness of different composite resins

Abstract

Aim: This study examined the impact of periodontal prophylaxis paste and air-powder treatment on nano- and microhybrid composite resin surface roughness and color change. Materials and Methods: Thirty specimens were prepared from a nanohybrid and a microhybrid composite resin. The specimens were distinct into three subgroups, and the first color measurements were done. Then, a periodontal prophylaxis paste was applied to one of the subgroups prepared from each composite, and air-powder polishing was applied to the second subgroups, and specimens in the third subgroup were kept in distilled water. Then, the specimens were washed and stored in distilled water for 24 h. After storing, the specimens' mean color change and surface roughness values were calculated. The data were recorded and statistically analyzed. Results: The highest mean color change was observed in the microhybrid composite air-powder group while the lowest in the nanohybrid composite control group. The surface roughness of the air-powder specimens was statistically significantly higher than in the other groups. Conclusions: Depending on the kind of composite resin, periodontal surface treatments may have an impact on color and surface roughness. After periodontal therapy, the dentist should assess the current composite resin restorations.
