RESUMO
The objective of the present study was to assess the influence of energy and hydroelectrolytic beverages on the color stability and fluorescence of composite resins. Three composite resins (Amelogen, Filtek Z350 XT, and Filtek Bulk Fill) were analyzed at 4 different time periods: at baseline (T0) and after 1 (T1), 2 (T2), and 3 (T3) months of storage. Thirty specimens of each material were prepared and divided into subgroups (n = 10) based on the type of solution in which they were immersed for 1 hour a day at 37°C: distilled water (control), Red Bull, and Gatorade. Color stability and fluorescence tests were performed at each timepoint. Three-way repeated-measures analysis of variance (ANOVA) tests were used to evaluate the influences of material, immersion solution, and time on the color stability and fluorescence values (α = 0.05). The Bonferroni test was used as a post hoc test to compare the mean values between the groups (α = 0.05). For color change, ANOVA showed a statistically significant influence of all isolated factors and their interactions. Overall, for all periods of analysis, Amelogen showed significantly higher fluorescence values than the other composite resins after storage in all solutions. In this in vitro study, energy and hydroelectrolytic beverages altered the color stability and fluorescence of the studied materials at all timepoints. The potential for future color alterations should be considered before anterior composite resin restorations are placed in patients who consume high quantities of these beverages.
