Chelating agents: their effect on the permeability of root canal dentin.

An in vitro assessment was made of the ability of three chelating agents used in endodontics to alter the dye penetration of dentinal tubules from the root canal surface. The experiment and control for this study were within the same root. It was found that all three agents significantly reduced the dye penetration into dentin, but there was no difference among the agents in the degree of reduction of dye penetration.

Dentin permeability: determinants of hydraulic conductance.

A technique is described which permits measurements of the ease with which fluid permeates dentin. This value, the hydraulic conductance of dentin, increased as surface area increases and/or as dentin thickness decreases. It increased 32-fold when dentin was acid etched due to removal of surface debris occluding the tubules.

[Studies of the permeability of human dentin Part I: Basic studies of constant physiological parameters and experimental variables (author's transl)].

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.
