Effects of five thermal stressing regimens on the flexural and bond strengths of a hybrid resin composite.

Unlabelled: Thermocycling is commonly employed in laboratory studies to simulate the in vivo aging of restorative materials. However, there is little consistency in the regimens used, and some researchers have questioned the clinical relevance and, hence, the necessity of including thermal stressing in in vitro protocols. This study examined the effects of five thermal stressing regimens on the flexural and dentin bond strengths of a hybrid resin composite.
