Effect of Delayed Exposure to Staining Agents on the Color Stability and Translucency of Esthetic Resin Composites

OBJECTIVE: To evaluate the effect of delayed exposure to staining agents and resin composite type on the discoloration and translucency changes of esthetic resin composites. MATERIALS AND METHODS: ) was calculated. Translucency parameter change (ΔTP) between baseline and 28 days was calculated. Data were analyzed by three-way repeated-measures ANOVA and Bonferroni tests (α = 0.05). RESULTS: but did not restore baseline appearance. CONCLUSION: Delaying exposure to staining agents for at least 7 days after polymerization enhances the color stability of resin composites. Clinical guidance on avoiding early staining exposures and selecting stain-resistant materials may improve long-term esthetic outcomes.
