Özet
Introduction: The release of residual monomers from dental restorative materials is a critical factor influencing their biocompatibility and long-term performance. In pediatric dentistry, materials like composite resins, compomers, and giomers are commonly used due to their aesthetic and functional properties. The aim of this study was to compare the release of residual monomers from three common pediatric restorative materials via high-performance liquid chromatography (HPLC). Materials and methods: Three restorative materials (3M Filtek One Bulk Fill Composite, Dentsply Sirona Dyract XP Compomer, and Shofu Beautifil 2 Giomer) were used. The amount of residual monomer released at each time interval was determined via HPLC. Discs of the restorative materials to be examinedwere prepared using standard Teflon molds for each group (n=7), and the materials were polymerized using an LED light source according to the manufacturers' recommendations. The data were statistically analyzed via IBM SPSS V23. Results: The retention times for the Bis-GMA, UDMA, and TEGDMA standard monomers were 6.7, 5.6, and 4.4 min, respectively. Residual release of Bis-GMA and UDMA was detected from all the materials, whereas TEGDMA release was not observed in the giomer. Significant differences in monomer release quantities among the restorative materials were observed over time, including in total residual monomer release. Conclusion: Compared with the giomer and compomer materials, the composite material resulted in lower residual monomer release. Further research and measures are needed to minimize residual monomer release and improve polymerization in restorative materials.
