The comonomer triethyleneglycoldimethacrylate (TEGDMA) is a commonly used constituent of resin-based dental materials. Upon placement, light-cured dental polymers may release a wide spectrum of residual compounds due to incomplete monomer-conversion during polymerization. Apart from liberating unreacted monomers, additional compound release might occur due to mechanical wear and enzymatic degradation on the salivary surface of resin fillings. Following delivery into the local bio phase, leached compounds may encounter a variety of different enzymes, which might be present in their oral or systemic environment. Metabolic by-products formerly associated with TEGDMA-degradation include triethylene glycol (TEG), methacrylic acid (MA), 2,3-epoxymethacrylic acid (2,3-EMA), and formaldehyde.
