Comparative Evaluation of Compressive Strength & Diametral Tensile Strengthof Calcium Aluminate Glass Ionomer Luting Cement with Three Other CommerciallyAvailable Luting Glass Ionomer Cements: An In-Vitro Study

ObjectivenbspTo evaluate and compare the compressive strength and diametral tensile strength of Calcium Aluminate Glass Ionomer cement Ceramir with three other commercially available glass ionomers namely Fuji 1 Meron Plus and Shofu HY Bond. nbspMethodologynbspFor the study a total of 160 samples were used. Four different glass ionomers were grouped as Group I II III amp IV. Each group was tested for compressive and diametral tensile strengths before and after storage in artificial saliva for 24 hours. All the samples were tested using Universal testing machine. The load at the fracture point of specimens was noted and the strength value was determined. nbspResultsnbspThe values recorded for compressive strength were Group IV gt Group II gt Group I gt Group III among the control groups and Group IV gt Group II Group III gt Group I among storage groups. The values recorded for diametral tensile strength were Group IV gt Group I gt Group III gt Group II among the control groups and Group IV gt Group I gt Group II gt Group III among storage groups. The study also showed a significant increase in compressive and diametral tensile strength values of individual cements after storage in artificial saliva for 24 hours except for Meron plus which showed a reduced diametral strength after storage. nbspConclusionnbspWithin the limitations of the study it can be concluded that Ceramir demonstrated intermediate compressive and diametral strength values whereas Shofu HY Bond glass ionomer showed the highest compressive and diametral tensile strength values among all the cements tested.
