## Abstract The use of soft‐start photoactivation to reduce shrinkage stress has become widespread in restorative dentistry. However, an increased susceptibility to ethanol degradation of polymers formed by pulse‐delay photoactivation was reported. It was hypothesized that reductions in flexural st
