Water Sorption, Solubility and Staining Properties of Microfilled Resins polished by Various Methods

Abstract

Water sorption, solubility and staining properties of three microfilled resins and one conventional resin polished by various methods were studied.
Water sorption of smooth surfaces after 60 days was higher than those of white point-polished and finished surfaces, while smooth surfaces showed the highest solubility.
For polished surfaces of composite resins, white point-polished surfaces had the highest value of staining, followed in order by smooth and finished surfaces. Among microfilled resins, Superlux showed the highest value of staining whereas Microrest the lowest, correlating with the values of water sorption and solubility.
