Dielectric study on human teeth specimen

Electrical and dielectric properties of wet human teeth, in vitro have been studied in detail. The measurements are made in three directions namely lo ngitudinal, lateral-medial and anterior- posterior, at discrete frequencies 10 kHz to 1.5 MHz using impedance analyzer. The electrical properties of t eeth are found frequency dependent. Dielectric loss appears due to heat gen eration which decreases exponentially from 0.561 at 1 kHz to 0.002 at 13 MH z. It has been observed that the relation frequency is less than 10 kHz.
