FARKLI CAM İYONOMER SİMANLARIN RENK STABİLİTELERİ VE MİKROSERTLİKLERİ

Abstract

Objective Glass ionomers are preferred in many different treatment procedures in dentistry due to their positive features. The aim of this study is to evaluate the color difference and microhardness values of various glass ionomer cement after storing them in different solutions. Material and Method A total of 120 samples were prepared, including 40 of each of the Equia Forte, AHfil Silver, and Ionofil glass ionomers. Each glass ionomer sample was stored in distilled water, cola, tea, and coffee solutions. Color and microhardness measurements of the specimens were performed before and after a week before it was immersed in solutions. The color measurements of the samples were evaluated with a spectrophotometer and microhardness values were evaluated with Vickers microhardness device. For color analysis, color changes (ΔE) were calculated by obtaining the values of L*, a*, and b* of the samples before and after a week after being immersed in solutions. The data obtained were evaluated by variance analysis (ANOVA) and Tukey’s test. Results Except for specimens stored in cola for AHfil Silver, microhardness values were increased for all materials immersed in test solutions. The highest color change was obtained in coffee for Equia Forte, in the samples immersed in cola for AHfil Silver and Ionophil (p
