Composite surface roughness and color change following airflow usage

Abstract Background Esthetic dental restorations have gained increasing popularity. The surface of should be smooth enough to achieve maximum esthetics and prevent the adhesion microorganisms food particles. This study aimed assess roughness color change composite specimens following airflow usage. Methods In this in vitro, experimental study, 30 Tokuyama discs were fabricated randomly divided into three groups (n = 10) for use with calcium carbonate/bicarbonate powder conventional polishing FlexiDisc. was measured by profilometry while assessed measuring L*, a* b* parameters using spectrophotometry before (T1). then polished stain removal, their as well remeasured after (T2). Paired t-test Tukey’s test applied within-group between-group comparisons. Results Significant differences noted average (Ra) between carbonate (0.251 ± 0.014 ?m) sodium bicarbonate (0.421 0.208 ?m), FlexiDisc (0.207 0.076 ( P < 0.05). Regarding correlation at T1 T2, an inverse all except L*. other words, reduction decreased parameters. Conclusions Within limitations results showed that device used had no significant difference terms staining. Considering cost maintenance device, it is not suggested a suitable alternative procedures. Trial Registration Number : does involve human subjects.
