Implication

In vitro evaluation reveals variable water sorption and predominant TEGDMA monomer elution across commercial dental composites, indicating resin composition dictates chemical stability.

Key Points

To assess the water sorption and solubility behaviors of six proprietary composite resin materials and identify monomers eluted into an aqueous medium over time.
Tested water sorption and solubility across six composite resin materials stored in water for 4 hours, 24 hours, and 7, 60, and 180 days.
Identified and quantified eluted monomers from the organic resin matrix using high performance liquid chromatography (HPLC) paired with UV-spectra verification.
Water sorption increased until equilibrium for five of the six materials, with resin formulations demonstrating marked variations in solubility through both mass losses and gains.
Triethyleneglycol dimethacrylate (TEGDMA) represented the primary monomer released, achieving maximal eluate concentration at 7 days of immersion.
Quantifiable amounts of urethanedimethacrylate (UEDMA) and trace detectable levels of Bis-GMA were identified, whereas bisphenol-A remained undetectable across all test intervals.
