Purpose: To compare three different zinc oxide/calcium sulfate based temporary filling materials (Cavit G, 3M ESPE; i-Pro N, i-dental; Cavitimi, Imicryl) in terms of water sorption, solubility, expansion and brushing abrasion.
Methods: Twelve cylindrical shaped samples (6x2 mm) were prepared from each material to determine water sorption, solubility, and expansion. Dry mass (m1) and diameter (d1) of the samples were measured after desiccation, followed by saturated masses (m2) and diameters (d2) after 7 days of water immersion, then finally dehydrated dry mass (m3). Using these values, the water sorption, solubility, and expansion of the materials were calculated. 8x2 mm cylindrical shaped samples were prepared (n=10), and their masses were measured before and after brushing for brushing abrasion. One-way analysis of variance and post hoc Tukey tests were used for statistical analysis.
Results: Significant differences were observed in solubility (p<.05). Cavit G showed the highest solubility values whereas Cavitimi exhibited the least. Mass loss and expansion values were significantly higher in Cavitimi (p<.05). Cavitimi showed least water sorption (p<.05)
Conclusion: Cavitimi, a new temporary filling material, showed the highest values in mass loss and expansion but the lowest values in solubility and water sorption. Cavit G exhibited the greatest value in solubility.
