EVALUATION OF THE SHEAR BOND STRENGTH, MICROLEAKAGE AND COMPRESSIVE STRENGTH OF REINFORCED GLASS IONOMER CEMENTS USED AS PERMANENT RESTORATİVE MATERİALS

Abstract

In this study, it is aimed to compare the usage of reinforced glass ionomer materials such as high viscosity glass ionomer and giomer as a permanent restorative material with the composite resin in terms of the mechanical properties. In our study, three groups were used: Equia Forte, Beautifil II and Solare X. For the shear bond strength test; 48, and for the microleakage test; 27 extracted third molar teeth were used. A total of 30 samples were prepared for the compressive strength test. Shear and compressive strength tests were performed by using universal test devices. Standard class V cavities were prepared on the buccal and lingual surfaces of the tooth for the microleakage test. Thermal cycling (5-55oCx10.000) was applied to the restored teeth. According to the statistical analysis, difference was found between all groups in the shear bond strength, compressive strength and microleakage tests (p<0.05). Solare X has showed the highest shear bond strength. Equia Forte has showed the lowest value in the microleakage test. Beautifil II has showed the highest compressive strength. Reinforced glass ionomer cements have been determined to have similar and better mechanical properties than composite resin in all the tests except the shear bond strength test.
