Effects of Fluoride Varnish on Roughness of Polyacid-Modified Composite Resins at Different Temperatures: An In Vitro Study

Abstract

Aim: The purpose of this study is to determine how fluoride varnish materials applied to polyacid modified composite resins (PMCR) affect roughness at various temperatures. Materials and Methods: In total, 100 PMCR discs were manufactured for this in vitro study, and the hundred samples were randomly split into five groups of twenty samples each. The samples in four groups had their surfaces coated with fluoride varnish at varying temperatures (4ºC, 23ºC, 39ºC, and 55ºC), while the samples in the control group did not get this treatment. A heating device is used for fluoride varnish. A profilometer was used to measure the samples’ surface roughness values after application. The Kruskal–Wallis and Shapiro–Wilk tests were used for statistical analysis. Results: After comparing five groups with twenty samples apiece, it was found that 23ºC had the greatest average roughness value. For the fluoride varnish material cooked at various temperatures, there was no discernible statistical variation in the roughness values. Conclusion: The study’s results indicate that all groups’ surface roughness values following the application of fluoride varnish at varying temperatures were found to be clinically acceptable.
