Effects of the Measuring Sensors Frequency Response on the Interpretation of the Results of the Impedance Measuring of Hard Tooth Tissues

摘要

Frequency response analysis is an informative method that allows exploring the properties of various objects. It is extremely difficult to determine the porous objects structure using this type of analysis due to the low conductivity of air. Filling the pores and micropores with a liquid of known conductivity can help to solve this problem. Thus, this paper is dedicated to solving problems associated with in vitro experimental studies of the frequency dependence of impedance of hard tooth tissues when microspaces in dentin and enamel are filled with liquid of various properties. The paper shows that the key issue of the research is to correctly interpret the information obtained by using the measuring equipment. Based on the results of numerous experiments, it has been shown that the measuring sensor properties determine the frequency range in which correct measurements of hard tooth tissues frequency response can be carried out.
