title: Impedance of amalgam-dentin interface in cat tooth.
abstract: The impedance between two amalgam electrodes implanted in the maxillary canine of a cat was measured at various frequencies between 0.02 kilohertz (kHz) and 100 kHz. When plotted on the X-R plane as a function of frequency, two types of impedance loci were obtained. One resembled a circular are at low frequencies, whereas the other was parabolic or exponential in formmthe circular-arc loci are similar to those calculated from membrane models. The parabolic or exponential loci are predicted by a polyelectrolyte model.
