The Monomer Elution of Bulk-Fill Sculptable Composite and Flowable Composite after Photopolymerization

Introduction: Composite resins have excellent mechanical properties, including fast polymerization,aesthetic quality, easy handling, and the ability to adhere enamel surfaces. However, there are alsosome disadvantages from this material, one of them is residual monomers. Bulk-fill composite areavailable in sculptable (solid) flowable (liquid) form. Most resin matrix aromatic oraliphatic acrylates. Bis-GMA, UDMA, TEGDMA monomers that commonly used butshow a high cytotoxicity level. They also poor properties such as wear resistance, hardness,tendency change color, may cause pulp reactions. Aim: The aim study was investigate thenumber bulk-fill composites submersion 75%ethanol solution (10 minutes, an hour, 24 hours). Methods: Sculptable wereused study. Samples (4 mm thick, 5 diameter) were prepared polymerized for 10 secondswith intensity 1025 mW / cm2 light emitted diode (LED). After sample made, each samplewas immediately immersed 75% ethanol extraction liquid stored amber-coloredbottles at room temperature. taken many 7 cc intervals 24hours. analyzed by High-Performance Liquid Chromatography (HPLC). data obtainedwere using Kruskal-Wallis Test, Independent T-Test Mann-Whitney Test significancelevel p <0.05. Result: amount elusion remaining compositewas higher than composite. UDMA bulk fill submersed hours highest among other Conclusion: Residual monomerseluted inside all time periods eluted increaseswith time.
