Effects of commercially available toothpastes on the surface roughness of a universal nanohybrid composite resin: A Profilometric study
Abstract
Aims: The aim of this in vitro study was to evaluate the effects of different commercially available toothpastes on the surface roughness of a universal nanohybrid composite resin following simulated toothbrushing.
Methods: Eighty cylindrical specimens of a universal nanohybrid composite resin were prepared and randomly assigned to ten groups (n = 8), including nine toothpaste groups and one control group brushed with distilled water. Surface roughness (Ra, µm) was measured before and after standardized simulated toothbrushing using a contact profilometer. Toothbrushing was performed with an electric toothbrush and toothpaste slurry prepared at a 1:1 ratio. Statistical analysis was conducted using the Wilcoxon Signed-Rank test, Kruskal–Wallis test, and Mann–Whitney U test with Holm–Bonferroni correction (? = 0.05).
Results: All groups demonstrated statistically significant changes in surface roughness after brushing (p = 0.0078); however, the magnitude and direction of change varied among the toothpastes. Significant differences in ?Ra values were observed between certain groups (p < 0.05). One toothpaste group exhibited a reduction in surface roughness following brushing.
Conclusion: Different toothpastes produced varying effects on the surface roughness of nanohybrid composite resin. Although some whitening and herbal toothpastes increased surface roughness, the changes generally remained within clinically acceptable limits. These findings highlight the importance of toothpaste selection for patients with composite resin restorations.
