Stress development profiles for BisGMA/TEGDMA (7:3 mass ratio) resin photopolymerized with 0.1 wt% 2,2-dimethoxy2-phenylacetophenone at 320–390 nm for up to 4 min. Different exposure times and irradiances were used to obtain dynamic stress (left) and final stress levels (right) related by conversion.
