GONZALEZ-LOPEZ, José Abraham et al. Hydrophobic Composite Resins Using a Novel Allylic Urethane Monomer as Additive. J. Mex. Chem. Soc [online]. 2019, vol.63, n.4, pp.105-114.  Epub 14-Sep-2020. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v63i4.877.

The purpose of this study is to report the formulation of photopolymerizable composites resins with hydrophobic behavior using a new urethane monomer (ETODC) as additive. The ETODC monomer was used together with Bis-GMA and TEGDMA to formulate a new organic matrix system. Mechanical and hydrophobic behavior were studied, also volumetric shrinkage, polymerization kinetics and cytotoxicity were analyzed. Results were compared with a control resin prepared with Bis-GMA and TEGDMA. The results show that mechanical properties and volumetric shrinkage did not present statistical differences between the studied groups. When compared with the control material, the experimental resin formulated with the ETODC monomer showed higher hydrophobic behavior and higher values of degree of conversion and polymerization rate.
