I fail to see what ultra "sound" has to do with electrical conduction.
Seems more likely that the gel is being used to interface and transmit the
*sound* thus electrical conductivity won't matter at all...only viscosity
and density and any fairly thick heavy gel will do the same thing.
Be aware that ultrasonics of any real intensity will make small hard
objects [like little bones ] very hot ...very quickly.
CS gel will conduct electricity as will salt water gel depending on the
concentration of substances [like salt] that will transport electrons via
electrochemical ion exchange.

My question is about the electrode conducting gels. I bought an
ultrasonic handdeld device for working on my teeth (via outside the cheek)
and haven't used it yet because it says to use a conducting gel with it.
So I'm wondering if there's anything special about a conducting gel? I
have Ode's gel making kit that I have not used yet. Will any gel work or
do I need to buy gel made specifically for conduction? Will plain water
do, or does it need the gel to keep the skin 'wet' because with water only
it could dry out during a 10 to 20 minute use?
