Abstract (2. Language): 
The aim of This study was in lent of marginal ridge strength of" glass ionomer cements with different structure. Kor thi s reason, e I ah s II cavity was prepared on premolars which sixty-five intact and without restoration and these cavities were rcslorated with metal-reinforced and high viscosity glass ionomer eements. The prepared samples were subjected to resistance test against pressure with cross-head speed 0,5 inch/in in by using Hounsfield Tensometer and the data were recorded in Newton (N). The control group was show the highest, though Medifil Silver group was shown the lowest mean value- The mean values obtained from the other groups were as lolluws fur each material: Argion Molar (160-30,55 N), Medifil IX (161+36.35 N), Fuji IX Capsul (184+36,27 N), Medifil IX Capsul (197+48,32 N) and Kuji IX (224+43,51 N). The data obtained was analyzed with the one-way ANOVA and Duncan multiple range test. There was statistically significant difference between groups (P<0.00l).
Abstract (Original Language): 
Çalışmamızın amacı, farklı yapıya sahip olan cam-ionomcr simanlarm marjinal sırt dayanıklılığının test edilmesidir. Bu amaçla, 65 adet çiiruksü/. ve restorasyondu/ küçük azı dişi üzerinde sınıf II kav ite hazırlanarak, metal ilaveli (Argion Molar ve Medifil Silver) ve ytlksek visko-ziteli (Mcdılîl IX, Kuji IX, Medifil IX kapsül ve Fuji FX kapsül) restoratif cam ionomer simanlar ile restore edilmiştir. Hazırlanmış örnekler kırıcı uç yardımıyla 0,5 inch' dak'lık başlık hızıyla kuvvet uygulanmış ve değerler Newton (N) cinsinden kaydedilmiştir. En yüksek ortalama değer kontrol grubundan elde edilirken [ANA 2000 (366±82,8Ü N)J, en düşük ortalama değer Medifil Silver (145+30,83 N) grubundan elde edilmiştir. Diğer materyallerden elde edilen ortalama değerler şu şekildedir: Argion Molar (160+30,55 N). Medifil IX (161+36,35 N), Kuji IX Kapsül (184+^6^7 N), Medifil IX Kapsül (197±4832 N) ve Fuji IX (224±43„5I N). KIde edilen değerler,istatistiksel olarak tek yönlü variyarıs analizi ve Duncan çoklu karşılaştırma testi ile değerlendirilmiştir. Gruplar arasındaki farklılık, istatistiksel olarak önemli (P<0,001) bulunmuştur.
