Abstract (2. Language): 
Although glass ionomer cements have got some differences according to their manufacturers and usage, they generally contain calcium floro-alumino silicat glass powder andpolyacrylic acid, itaconic acid and tartaric acid. Studies showed that these materials can compansate the loss tissues of the tooth very well due to structural properties. Cermet cements containing silver-glass particules are more resistable to pressure. Using glass ionomers prevent seconder caries due to releasing offlourur ions. These materials produce chemical bonding with tooth tissues. So dentists can treat the teeth very conservatively. In addition to this, the remaning dentin thickness onto the pulp is very important for the reaction of pulp to glass ionomer cements Surface characteristics and usage procedures of the glass ionomer cements affect the clinical success.

Abstract (Original Language): 
Kullanım alanları ve üreticilerine bağlı olarak, bazı farklılıklar taşımakla beraber, genel olarak cam iyonomer si-manlarının yapısı, kalsiyum floro-alumino slikiat cam tozları ve poliakrilik asidin akıcı solüsyonu, itakonik asit, tartarik asit İçeren kopolimer bileşiminden ibarettir. Yapısal özellikleri nedeniyle diş doku kayıplarını en iyi şekilde karşılayabilecek nitelikte materyaller oldukları çeşitli çalışmalarla ortaya konmuştur. Materyalin yapısına katılan, küresel gümüş alaşım tozlan ve sinterlenmiş cam-metal tozlan dolayısıyla aşınmaya direncinin önemli ölçüde arttığı bildirilmiştir. Cam iyonomer simanları sekonder çürükleri önlemek açısından diğer dolgu maddelerine göre daha üstün özelliklere sahiptir. Bunun başlıca nedeni, yapılarında fluorür iyonu bulunması ve bunu serbestleyebil me yeteneğinde olmalarıdır. Ayrıca diş dokularına kimyasal olarak, mine ve dentin dokusunun hidroksiapatitine kalsiyum iyonları ile şelasyon reaksiyonu sonucu bağlanması bu dolgu maddesinin dişte fazla madde kaybı olmaksızın kullanılmasını sağlayan üstün bir özelliğidir. Canlı dokuya etkisine ilişkin özelliklerinin bilinmesi, bırakılacak sağlıklı dentin kalınlığını, yüzey özelliklerine ilişkin karakterinin anlaşılması, klinik uygulamasının başarısını belirlemek açısından son derece önemlidir.
