Abstract

Due to the recently indicated causal relationship between the piezoelectric properties of teeth and the formation of root caries, a study was undertaken to further classify the dielectric properties of the actual tooth constituents. The properties considered are the real and imaginary components of the complex dielectric constant, including the electrical conductivity, for human teeth in vitro, both dry and saline solution saturated. The frequency range covered is from 1 Hz to 1.35 GHz. An attempt has been made to present the data for the two most prominent constituents, namely, enamel and dentin. Ways in which the dielectric properties can aid physiological studies and an understanding of the caries process are also described. Some possible explanations for the biological and physiological processes in the dielectric properties of tooth constituents are given. Pathological variations among teeth are noted. Some hypotheses for causal relationships between caries and electrical properties of natural dental constituents are proposed.
