A comparative study of solubility between resin cement and self-adhesive resin cement

open access: yesInternational Arab Journal of Dentistry, 2013
Resin cements have been largely used for luting indirect restorations due to their bonding abilities to the tooth structures and the increase of the restorations stability; however their solubility can negatively affect the restoration durability. The aim of this in vitro study was to evaluate and to compare water solubility values of conventional ...
