Electrical order
BillyFish
"Electrical Order" which is a term from a book by Wendy Lydall. The brief
information in the posting may be incomplete, but to a physicist like me,
this smacks of pseudoscience. No mention is made on how the current
flows. The amalgam in a relatively low conductance electrolyte may have a
potential, but where is another electrode and what is the circuit? Is
this concept just another way of extracting money by scaring patients?
What is the rationale, if not proof, behind electrical order>

Our news has been down, and I've just come upon this.
I think the main point is that fillings need/should not be changed if the
"charge" is of less magnitude than 7 microamps.
I think that when a current meter is used, the current which flows,
gradually, over a few seconds, decreases, as if discharging a battery, and
it is the initial current flow which should be considered.
I have used a high resistance digital voltmeter to measure the voltage on my
fillings, either from a moistened finger to each filling, or between
fillings.
Between fillings gives a good result. the fillings can be dry, and there is
no question of electrolytic potenetial between the meter probe and the
filling.
The voltages add and subtract quite predictably between fillings.
I imagine that the circuit is through the moist nutrient solution coming up
through the pulp and dentine of the tooth, but I'm not sure about the
enamel.
Over a period of about a year, I measured my filling voltages, and the
results were very similar each time. I must try to find my old results and
do it again. From memory, voltages were about plus or minus 30 millivolts, a
bit more or less, some may be 70, but one filling had about 280 millivolts,
over a quarter of a volt. And it was similar at each testing session.
Say the resistance of the body is 400,000 ohms, by ohms law, I speculated
this would give a current of 0.280/400,000 Amps or 7 microamps.
Being a voltmeter, this voltage stays constant - the battery does not
discharge and have to be read quickly as it does with a current meter.
That filling was changed because the tooth was sore to bite on, but I might
not even have had it changed if I had discovered (calcium) fluoride before.
Try it on someones fillings, you may be able to stop them from going to the
cost of changing.
Usually, electrolytic products are formed when current is flowing from a
battery, and perhaps that is one reason for wanting less current in the
mouth.
Perhaps some of the cause is the different types of amalgam which dentists
have used. They can have varying amounts of copper, etc. Like the dissimilar
metallic poles of a battery, they will produce different voltages. The
normal zinc - carbon cell is 1.5 volts but a mercury hearing aid cell is
rather less - I'm not sure what the other metal used is in a mercury cell.
Somewhere I seem to remember even the ADA talking about measuring oral
galvanism, but perhaps more between gold amalgam and silver mercury
amalgam.
Electroacupuncture, working with the body's meridians, is quite established
now, and may be what to research for further thought on this matter.
The taste of my composite fillings is still much stronger than the
electrolytic taste of my amalgams, and I wonder what it does to my health.
Taste and eating are an important part of normal sensory input. We get
densensitized to constant smells or even sounds, but a constant ringing in
the ear - a tinnitus can be most debilitating if it is too loud. Masking the
sound is sometimes possible, and masking the taste sometimes helps. When I
first reported my composite trouble to the poisons centre and was referred
to the dental school I was told that the taste can be stronger if the mouth
is kept very clean. I'm still thinking about this.

"Smacks" is hardly the word, William! Thanks for having
the guts to post what many of us were thinking. Your
contributions as a physicist are most welcome.

I don't think you had read my 23rd Feb article when you wrote this.
I should add that it is possible that since the fields are DC (direct
current with no oscillation), that the body _might_ adjust to them better
than to low frequency fields.
The magnetic field of the Earth is static, though at about 500 milli-Gauss
it is much stronger than the few milli-Gauss fields of computers and other
electrical equipment and wiring which are the subject of much discussion.
A constant smell or sond may get adjusted to whereas one which is present
for short times is more noticed.
is more noticed.
