Flexural strength of fluorapatite-leucite and in cyclic immersion

O materials (IPS d.SIGN and IPS e.max Ceram) exposed to erosive agents. Material and Methods: One hundred and twenty bar-shaped specimens were made from each of !" #" $%& !" # ' & and divided into 8 groups of 15 specimens each. Six groups were alternately immersed in the following storage agents for 30 min: deionized water (control), citrate buffer solution, pineapple juice, green mango juice, cola soft drink and 4% acetic acid. Then, they were immersed for 5 min in deionized water at 37°C. Seven cycles were completed, totalizing 245 min. A 7th +/ 69;' <= # > ? 8th, group was stored dry at 37°C for 245 min. Three-point bending tests were performed in a universal testing machine. The data were analyzed statistically by 2-way ANOVA, @ B D"E > 9#9H# J of all groups of each porcelain after exposure to erosive agents in cyclic immersion did > K9#9H&# L ?
