Abstract (2. Language): 
The purpose of this study was to investigate the fluoride release and pH properties of three different glass ionomer cements and compare the pH zones of the materials due to time periods. For. this aim, Ketac - Cem, Aqua - Cem and Chem - Fil glass ionomer cements were used. Acid diffusion assay methodology was applied to measure the acid zones and initial pH values of the materials. Fluoride diffusion methodology was used to determine the amount of fluoride releases of the materials (n = 4). Findings were evaluated by using Kruskal - Wallis statistical method. The highest fluoride release was obtained from Ketac - Cem material. Aqua - Cem and Chem - FU materials followed Ketac - Cem cement. Differences between the materials were found significant (p = 0.007). The lowest initial pH was also obtained from Ketac -Cem material and it was followed by Aqua - Cem and Chem - Fil. Significant differences were found between the materials (p = 0.007). The biggest acid zone was obtained from Ketac- Cem and the smallest zone from Chem-Fil for three time periods and the differences were found statistical significant (p = 0.006).

Abstract (Original Language): 
Bu çalışmanın amacı, üç farklı cam iyonomer simanının fluorid serbestleme ve pH Özellikleri yönünden incelenmesi ve bu materyallere ait pH zonlarının zamana bağlı olarak (30, 60 ve 120 dakika) değişimlerinin karşılaştırılmasıdır. Çalışmada Ketac Cem, Aqua Cem ve Chem Fil cam iyonomer simanları kullanıldı. Materyallerin asit zonlarının zamana göre Ölçülmesi ve başlangıç pH değerlerinin belirlenmesi için asit diffüzyonu metodu uygulandı (n = 4). Sonuçlar, Kruskal - Wallis metodu ile istatistiksel yönden değerlendirildi. Fluorid serbestleme yönünden en yüksek değer, Ketac Cem mateıyalinden elde edildi ve bu simanı Aqua Cem ve Chem Fil 'materyalleri izledi. Materyaller arasındaki farklar anlamlı bulundu (p - 0.007). Başlangıç pH değerleri açısından ise en fazla asit karakter taşıyan materyal, Ketac Cem olarak belirlendi ve bu mateıyali aralarında anlamlı farklar oluşturarak Aqua Cem ve Chem Fil materyalleri izledi (p = 0.007). Zamana bağlı olarak pH zonlarının incelenmesi sonucunda, her üç zaman dilimi içinde de en geniş asit zonu Ketac Cem materyali ile elde edildi. En küçük asit zonu ise her üç süre için Chem Fil simanı çevresinde belirlendi. Aralarındaki farklar istatistiksel yönden anlamlı bulundu (p = 0.006).
