Thermal diffusion in some polyelectrolyte dental cements: the effect of powder/liquid ratio.
Thermal diffusivity values for glass ionomer and polycarboxylate cements have been determined for varying proportions of cement powder and liquid. Diffusivity is observed to be an increasing function of powder/liquid ratio. This is discussed in relation to the application of these cements as cavity bases.
