COMPARISON OFWATER SORPTION AND SOLIBILITY OF DIFFERENT RESTORATIVE MATERIALS

26149

Objective: The aim of this study was to compare the water sorption and solubility of different aesthetic restorative materials. Material andMethod: Four composite resins (hybrid composite resin – Filtek Z250 (FZ), nano-filler posterior composite resin – ClearfilMajesty Posterior (CMP), silorane based composite resin – Filtek Silorane (FS) and flowable composite resin – Premise Flowable (PF)), a polyacid modified composite resin - Dyract Extra (DE), a resin modified glass ionomer - Fuji II LC (FL) and a conventional glass ionomer cement -Aqua Ionofil Plus (AIP) were used in this study. Ten prepared samples of 10 mm diameter and 2 mm height were kept in the incubator for 24 hours at 37oC. The samples were weighed, placed in distilled water and then incubated at 37oC.After 24 hours the five samples were taken from the water and weighed again. The samples were then dried in the incubator for 24 hours. The dry samples were weighed again. The same process was applied to the other five samples which had been stored in water for 7 days. The water sorption of the materials and their solubility were evaluated according to the ISO standards (ISO 4049). Results: Conventional glass ionomer cement,AIP showed the most solubility and water sorption compared to the other tested materials (p 0.05). The lowest results were obtained from polyacid modified composite resin, DE. When compared to the other composite resins, silorane based composite resin, FS showed increased solubility and water sorption. Conclusion: The differences in the structural features of the restorative materials may influence their water sorption and solubility behaviors.
