Glass ionomer cement is used as a restorative material. This study evaluated some physical properties such as specific heat, thermal conductivity, vickers hardness and breaking strength of Glass ionomer cement (GC Fuji II - Tokyo). The specific heat and thermal conductivity were determined using the principal of method of mixtures and Lee's apparatus respectively. Micro hardness measurements were performed using a Vickers cum Brinell hardness tester and measurement of breaking strength was carried out using a universal testing machine, operated at a head speed of 10 mm per minute. Glass ionomer cement has several desirable properties such as high specific heat, low thermal conductivity and thermal diffusivity apart from greater Vickers hardness and breaking strength. In presence of these advantages it may be a cement of choice for filling of cavities. [ABSTRACT FROM AUTHOR]
