Overview

Randomized trial evaluates surface treatments on color stability and roughness in composite resins, highlighting effective techniques.

Key Points

  • This study aims to evaluate how different surface treatments affect the optical properties of bleach-shade composite resins after exposure to coffee.
  • 300 specimens prepared from five composite resins, randomly allocated to six treatment groups, n=10 per group.
  • Specimens immersed in coffee for 12 days and assessed for color stability and surface roughness at three time points (t0, t1, t2).
  • Statistical analyses employed include Kruskal-Wallis, Dunn, and robust ANOVA with a significance level of p<0.05.
  • All specimens showed clinically unacceptable ΔE00 after coffee exposure and decreased whiteness index at t1.
  • The Asteria resin exhibited the highest color stability, while Brilliant and A’chord resins had the highest whiteness index (p<0.05).
  • At t2, surface roughness increased with bleaching, but one-step polishing achieved the lowest roughness values (p<0.05).
