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
