Hi friends, I need your help! I am trying to measure tooth impedance, I thought to make a wien bridge oscillator and then to balance it and to connect it through a resistor to a tooth which the equivalent circuit is a R-C parallel. I found the equations but I don't know how I can calculate the phase shift, is any appropriate circuit for that?
Of course any other ideas how I can calculate the R-C of the tooth welcome.
Also I thought to use an apex locator but I can't find any circuit for that, Does anyone has any simple circuit for apex locator?
Thank you
