Özet

Aim Resin materials are usedfor restoration or fissure sealant in pediatric dentistry andconsist of different types of monomers (BISGMA,UDMA,HEMA,TEGDMA). Monomers can be released into the oral cavity after polymerization. Residual monomers released after polymerization from resin-based restorative materials have been reported to affectthemechanical specialty negatively. Besides, allergic,cytotoxic,and carcinogenic effects are showed. Our study aimsto identify the substances and thedetermination of quantitiesreleased from the material into the oral environment Material & Metods Disk sizes (2 mm) prepared for each material group (flowable composite resin-pink&blue, packable composite resin-pink,blue,yellow and A2, fissure sealant and RMCIS) were polymerized by LED light; the specimens were then placed in %75 ethanol-water. The monomer release in 10min, 60min, 1hr, 1day, 7days, and 14 days from the specimens was analyzed in HPLC. One-way ANOVA, Post-hoc, Tukey HSD tests were used for statistical analysis. Results The amount of residual monomer increased overtime. At the end of the 14th day, the maximum monomer releasedfrom the materials was BISGMA (mean; 50.17±3.7). No significant difference was found inTEGDMA release between the flowable and the packable compomers. The amount of total monomer releasedfrom A2 compomer was higher than fromthe blue and pinkcompomer(p<0.001).Yellow compomer was with the highest monomer release(p<0.001). Conclusion The color factor in the compomers is effective on residual monomer release. Polymerization should be strengthened to reduce theresidual monomer release from colored compomers. More studies are needed to investigate invivo and invitro about the different light-curing unit&polymerization periods.
