Water sorption and desorption of different types of direct tooth-clored restorative materials

Abstract

The objective was to evaluate the sorption, desorption and material net loss for different direct tooth-colored restorative materials. Six different direct tooth-colored restorative materials (Z-100, Glacier, Wave, Ketac-Molar, Vitremer, and Compoglass F) were used. Thirty-six disk-shaped specimens (6/material) were fabricated in a cylindrical rubber mold (15 mm × 2 mm). The specimens were subjected to sorption, and desorption cycles, and the percentage values of sorption, desorption, and material net loss calculated. Data were analyzed using a one-way ANOVA and Post hoc Tukey’s multiple comparison tests (á = 0.05). The results of sorption and desorption showed that the least changes were for Glacier and the most changes were for Ketac-Molar. If it is assumed that sorption would influence the staining of restorations then Ketac-Molar would be the most susceptible while Glacier would be the least. The solubility, based on the amount of material lost, appeared highest for Ketac-Molar and lowest for Z-100 and Vitremer.
