ترجمة الملخص

Background and Aim of study : Glass ionomer restorations were developed and modified to improve its properties . Recently zinc was added to glass ionomer restorations , and in this study we’ll investigate the solubility and compressive strength . Aim of study : to Compare the Solubility and compressive strength of zinc-reinforced glass ionomer, high viscosity glass ionomer and composite resin According to Variation time factor .Materials and Methods: A Laboratory study was conducted to compare the solubility of 48 samples ( 8 in each group ) in the form of circular disks ( 15 mm diameter, 1 mm height ) of zinc-reinforced glass ionomer Chemfil Rock , Dentsply , high viscosity glass ionomer Fuji IX GP Fast , GC and composite resin Rok , SDI . ( 24 samples direct – 24 samples after 24 hours ) , after preparation and finishing Specimens were immersed in Artificial saliva for 7 days, and the loss of weight was measured after immersion to calculate Solubility , 24 samples ( 8 in each group ) in the form of cylinder ( 4 mm diameter, 6 mm height ) of same materials ( 24 samples after 24 hours – 24 samples after 7 days ) , after preparation and finishing the compressive strength test was performed by device for measuring the pressure forces at a crosshead speed of 0.75 mm/s. The results were recorded and analysed statistically by using ANOVA Test ( P ≤ 0.05 ) and student –t tests .Results: The results showed statistically significant differences between the solubility values of the three materials in two tests , and showed non statistically significant differences between the compressive strength values of each of zinc-reinforced glass ionomer and high viscosity glass ionomer, while there was statistically significant differences between the last two types of glass ionomer and composite resin in two tests. Conclusions: The solubility of the zinc-reinforced glass ionomer is less than high viscosity glass ionomer and greater than the composite resin in two tests, the solubility of three materials was decreased after 24 hours , as for the compressive strength of two types of glass ionomer was similar and they were less than the composite resin in two tests , the compressive strength of two types of glass ionomer was increased after 7 days while the composite resin has not increased.
