Abstract

Aim: The purpose of the study was to determine the water sorption and solubility of three experimental flowable composite resins (EXP1, EXP2, and EXP3), which differed only in their filler amount (65, 55, and 45wt%, respectively) with a view to assessing the relevance of this parameter. Materials and methods: The ISO 4049 protocol was followed. Ten discs (15 × 1mm) of each material were submitted to a drying cycle at 37°C for 35 days, after which the constant mass (m1 ) and volume (V) of each were measured. The samples were then immersed in distilled water at 37°C for 168 hours and weighed to determine the constant mass (m2 ). A final drying cycle, identical to the first one, allowed to record constant mass (m3 ). Water sorption and solubility were calculated by using these measurements. Results: EXP1, which had the highest filler amount, absorbed significantly less than the other two materials. EXP1 was also significantly less solubilised. EXP3, which had the lowest filler amount, absorbed significantly more than the other two materials and was also significantly more solubilised. Conclusion: Within the limitations of this experimental study, it was shown that a high filler amount, without affecting the spreading capacity of a flowable resin composite, could reduce water sorption and solubility. Clinical significances: Given the clinical importance of water sorption and solubility on the behaviour and sustainability of dental restorations, a high filler amount could be a major criterion to be taken into account by dentists when they are selecting flowable composite resins.
