Impedance of dental enamel membranes as a predictor for their permeability

Medical and Biological Engineering and Computing, 1982
The permeability of dental enamel membranes can be estimated by means of diffusion-measurements with radio-isotopes. Because of the low intrinsic permeability of these membranes, determination via this route generally takes two weeks. In this paper a much faster electrochemical method is presented, in which the real and imaginary part of the membrane ...

Effect of laser irradiation on the permeability of bovine dental enamel

Archives of Oral Biology, 1980
The transport of ionic and non-ionic compounds through bovine dental enamel was measured before and after irradiation with a carbon dioxide laser (energy density 10J/cm2). The irradiation increased the permeability of enamel rather than decreased it as postulated by other workers to explain the increased resistance to surface demineralization produced ...

Effect of phytate and hexadecylamine on the permeability of bovine dental enamel

Archives of Oral Biology, 1983
The effect of hexadecylamine on the permeability of bovine dental enamel was investigated using a radiochemical diffusion technique. Treatment with an aqueous solution of hexadecylamine reduced the permeability of the enamel by about 20 per cent. Pre-treatment of the enamel with an aqueous solution of phytate followed by hexadecylamine yielded a ...
