Abstract:	In Pediatric practical dentistry, the dentist must take into account several factors such as morpho-structural peculiarities of temporary teeth, behavioral features of children, the clinical, physician performance and last but not least the quality of the chosen material Thus, we investigated the behavior of glass ionomers cements in occlusal stress by determining their mechanical properties. The study aims to determine the diametrical compressive strength values , which is one of the mechanical properties of filling materials, the strength of materials being useful in the research of occlusal forces exerted on the future restorations. The determination of values of the resistance in diametrical compression are important in choosing the materials for coronal restorations in cavities of first class and second class of Black at children. After a random choice of classes, we had used direct coronary restoration materials, selecting two glass ionomer cements, which then we have tested them to obtain comparative data, of the resistance for diametral compression.
Keywords:	glass ionomers, mechanical properties, compression diametrically, temporary teeth, coronary restoring
