Aim This study aims to comparatively investigate the color stability and microhardness values of dental composites with different photoinitiators.
Material and method In the study, Ivoclar Tetric N-Ceram, Dentac Parion, and FGM Llis composites were used. A total of 30 composite discs were evenly divided for surface microhardness and ΔE measurements. Each subgroup contained 5 composite discs (Diameter: 5 mm, Thickness: 2 mm). Before the experimental procedures, all composite discs were aged in a coffee solution for one week. Surface microhardness was measured using the Vickers Hardness Test device, while color stability was assessed with a spectrophotometer. One-way ANOVA and Two-Way Repeated Measures ANOVA with Bonferroni-adjusted pairwise comparisons were applied.
Results No statistically significant difference was observed among the three dental composite groups in terms of color stability (p > 0.05). However, their color stability performance ranked from highest to lowest as follows: Llis (3.13 ± 0.42) > Parion (2.76 ± 0.57) > Tetric N-Ceram (2.70 ± 0.76). In contrast, a statistically significant difference was detected among the groups regarding surface microhardness (p < 0.05). Llis exhibited significantly higher values compared to Tetric N-Ceram and Parion (p < 0.05).
Conclusion The compositional structure of the composite material and the photoinitiator mechanism used are directly related to the formation of its mechanical properties.
