Resumen

Objective: To evaluate the changes in the color of dental filling materials after being immersed in pediatric syrups for a period of time. Material and Methods: This study had a quasi-experimental design. Three restorative materials were employed: a conventional self-curing ionomer cement, a light-curing ionomer cement, and a light-curing composite resin. Forty disc-shaped samples of each material were prepared and randomly assigned to 6 subgroups (n=20). The samples were immersed in 2 pediatric drugs: paracetamol and ferrous sulfate, for 2 min once a day for 28 days. Color stability evaluations were performed at 7, 14, 21 and 28 days. The color variation of the materials was evaluated using a digital colorimeter. The Kruskal-Wallis test was used for intra-and inter-group comparisons. Results: In all subgroups, the total color difference values increased significantly from the first evaluation to day 28 (p < 0.05). Conclusion: Long-term use of pediatric syrups may affect the color stability of restorative materials. Among pediatric syrups, the composite resin showed the least color variation when immersed in paracetamol and ferrous sulfate compared to the ionomer materials.
