Virtual Instrument for Early Detecting Dental Decay Using Electrical Impedance Measurement Method

摘要

The paper presents a virtual instrument used to diagnose dental caries using NI data acquisition device and Lab VIEW software. We also use two electrodes to measure dental impedance and the results respect the domain litera ture. Combining hardware and software resources we obtain a flexible and versatile interface very friendly with the user (den tist). Compared to known methods our method is very simple, fast and does not cause pain to patient.
