[Studies of the permeability of human dentin Part I: Basic studies of constant physiological parameters and...

Diffusion processes proceeding in the dentin are of fundamental scientific interest and of major importance to numerous therapeutical measures, with the permeability of dentin playing an essential role. Their exact quantitative determination is possibly in vitro only and depends upon various factors. Relevant investigative results obtained using standardized parameters and the methods employed are subjected to a critical analysis and interpreted with regard to the possibility of using them for specific comparative studies. The results reported in this paper are only indirectly applicable to clinical studies. However, they can considered a useful starting point for further studies.
