OptiBond XTR and OptiBond FL were applied according to the specific directions supplied by the manufacturer. The preparations were restored with a light-cured nanoparticle resin-based composite material (Herculite Ultra). The composite was inserted in increments of 2 mm or less. Each increment was fully polymerized according to composite shade for no less than 20 seconds using a Demi Plus LED light-curing unit as determined and provided by the manufacturer.
