Light-Cured Dental Fillings Containing Quinoline and Quinoxaline Derivatives: The Influence of Sorption and Solubility on Color Change—Part III
Ilona Pyszka, Dawid Bereźnicki, Beata Jędrzejewska
TL;DR
This study examines how the composition of light-cured dental fillings affects their color stability and durability in the mouth.
Contribution
The study introduces new dental composites with quinoline and quinoxaline derivatives and evaluates their sorption, solubility, and color change.
Findings
Sorption and solubility increased with longer conditioning time in the oral environment.
Hydrophilic composites showed greater color changes (ΔE > 6) and higher sorption/solubility.
Materials with lower sorption and solubility had better color stability (ΔE < 5).
Abstract
Light-cured dental fillings play a significant role in modern dentistry due to their aesthetics, durability, and ease of application. However, research is still being carried out to improve their mechanical properties, biocompatibility, and wear resistance by modifying their composition. Therefore, the aim of this study was to evaluate the sorption properties, solubility, and color stability of newly developed dental composites containing quinoline and quinoxaline derivatives. A total of 162 samples were prepared by mixing organic and inorganic phases. For 144 of these, color changes were assessed after conditioning in solutions simulating the oral environment, and for 18, sorption and solubility analysis were performed in distilled water according to ISO 4049. The results showed that sorption and solubility increased with increasing conditioning time. Composites characterized by higher…
