In this work, the relationship between the degree of conversion (DC) in the Bis-GMA/TEGDMA polymer networks, determined by two methods—Fourier transform infrared spectroscopy (DC_IR) and polymerization shrinkage (DC_S)—was studied. The DC_IR was calculated by using the internal standard method, whereas the DC_S was calculated by measuring differences in the monomer and polymer densities, resulting in the polymerization shrinkage. Both methods revealed the same trend in the DC changes with alterations in the Bis-GMA/TEGDMA ratio. However, the DC_S values were lower, in comparison to the DC_IR values on average by 18%.
