Studies defining the characteristics of light curing units and photoactivation methods are necessary to allow the correct choices to be made in daily practice. This study aimed to determine whether different photoactivation protocols for composite resins [periodic level shifting (PLS) – 5 second and soft-start] are able to maintain or enhance the mechanical properties and marginal adaptation of restorations.
