The deposition of AgCl in the human tooth dentine was studied as a function
of the time and de electrical field using a scanning electron microscope a
nd by measurements of the frequency-dependent complex dielectric constant.
Dielectric properties of the tooth dentine can be well described by the mod
el which was recently developed for the dielectric response of hydrating po
rous cement paste. The fractal dimension of the tooth dentine was determine
d by the electron microscopy and dielectric spectroscopy techniques.
