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.
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).
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
