Bu çalışmanın amacı farklı restoratif materyallerin ısı iletim özelliklerinin incelenmesidir. Bu çalışmada iki tip amalgam, 3 tip cam ionomer siman CİS ve 3 tip kompozit incelendi. Bu materyaller, üretici talimatlarına göre hazırlanarak standart kalıplara uygulandı. Her materyale ait 3 örnek hazırlandı. Ölçümler Heat Conduction Unit P.A. Hilton ltd, England test cihazı ile yapıldı. Her örnek için ısı iletim katsayısı Fourier formülü kullanılarak hesaplandı. Katsayılar, Kruskal-Wallis testi ile istatistiksel olarak analiz edildi. Isı iletiminde bazı materyaller arasında önemli farklılıklar bulundu p < 0.05 . Amalgamın ısı iletim katsayısı diğer materyallerden daha büyük bulundu p < 0.05 . Amalgam örnekleri arasında bir fark bulunamadı p > 0.05 . Kompozit örnekleri arasında ve CİS’ler arasında önemli bir fark bulunamadı p > 0.05 . Bu çalışma, restoratif materyallerin ısı yalıtkanları olarak görev yaptıklarını ve farklı ısı iletim özelliklerinin onların içeriklerinden kaynaklandığını göstermiştir

Examination of the Heat-Conductive Properties of Amalgams, Composites and Glass Ionomer Cements

The aim of this study was to examine the thermal conductivity of different restorative materials. Two types of amalgam, three types of glass ionomer cement GIC and three types of composite were examined. These materials were prepared in accordance with the manufacturers’ instructions and applied to standard moulds. Three samples of each material were prepared. Measurements were taken using a Heat Conduction Unit P.A. Hilton Ltd. Stockbridge, Hants, UK . The thermal conductivity coefficient was calculated for each sample using the Fourier equation. Coefficients were analyzed statistically by the Kruskal–Wallis test. Significant differences were found for thermal conductivity between some materials p < 0.05 . The conductivity coefficient of amalgam was found to be higher than those of the other materials p< 0.05 . No significant differences were found between amalgam samples p> 0.05 . No significant differences were found between composite samples and no significant differences were found between GICs p> 0.05 . This study showed that restorative materials functioned as thermal insulators and had different heat-conductive properties that depended on their composition.
