It was first reported in 1823 that when a material consisting of an inhomogeneous mixture of dissimilar electrical conductors is subjected to a temperature difference, an electromagnetic disturbance can be detected near the surfaces of the material.There is no electrolysis involved in this phenomenon. A typical dental amalgam may be accurately described as an inhomogeneous mixture of dissimilar electrical conductors. However, and in spite of the fact that amalgam fillings are placed in children's

I would prefer the term "heterogeneous" to inhomogeneous, but I get it.

Thank you for your reply.
Both "heterogeneous" and "inhomogeneous" are in common use in thermoelectrics and, as can be seen from the following example, they are often taken to mean the same thing.

When a material comprising an inhomogeneous mixture of dissimilar electrical conductors is subjected to a temperature differential, the only way that the material can maintain electrical equilibrium is by the circulation of thermoelectric eddy currentsat the interfaces of the regions of dissimilar composition.

In view of the fact that amalgam dental fillings are placed in children's teeth, I find it surprising that the dental profession has never sought to establish the extent to which this phenomenon occurs in dental amalgams. I'm sure that no-one wouldseriously suggest that the materials used in restorative dentistry are exempt from the laws of nature. However it does rather give the impression that the dental profession is not particularly interested in science.

Hi Brian,
I haven't cited "contact potential difference" anywhere in my description of thermoelectric eddy currents in dental amalgams.
I'll explain it to you again.
When a material which consists of an inhomogeneous mixture of dissimilar electrical conductors is subjected to a temperature difference the only way that it can maintain electrodynamic equilibrium is by the circulation of thermoelectric eddy currents
If you think that you know of any reason why any part of this description is incorrect, I would be interested to hear it.called "psychiatric" disorders suffered by countless individuals over the last couple of centuries.
For my part I believe that individuals will never understand this properly if they continue to regard an amalgam as having the same degree of material homogeneity as a true alloy. It doesn't.
I'd also like to take this opportunity to put forward further guesswork of my own which at present is not contradicted by the evidence of any known experiment or experience.
The electromagnetic disturbances generated by metal amalgam dental fillings are able to dissipate electrical energy through the nerves in people's heads and, in so doing, they have been responsible for a large proportion of the neurological and so-
