Polymerization shrinkage stress for bulk photo-CuAAC polymerizations labeled as BZ-AZ (open circle) and a BisGMA/TEGDMA control denoted as (open square) taken after 10 min of reaction time as a function of functional group conversion using a tensometer. Each mixture was irradiated for 90 s at ambient temperature with varying light intensities of 400-500nm light – 500 mW cm⁻² (red), 400 mW cm⁻² (orange), 300 mW cm⁻² (green), 200 mW cm⁻² (blue), 100 mW cm⁻² (purple).
