Effect of aging and curing mode on the compressive and indirect tensile strength of resin composite cements

open access: yesHead & Face Medicine, 2017
Background Resin composite cements are used in dentistry to bond ceramic restorations to the tooth structure. In the oral cavity these cements are subjected to aging induced by masticatory and thermal stresses.
