- Abstract
Tooth carious is a harmful and enduring hurt to parts of the teeth' rigid surface that seem like small holes and cavities. Caries is caused by a summation of factors, such as creating bacteria between teeth, eating soft foods frequently, drinking sweaty drinks, and not brushing the teeth right. The present study aims to design and implement an electrical circuit for measuring the electrical impedances of healthy and carious teeth. Besides, the LCR meter analyser was employed to calculate the electrical average impedance and phase shift of healthy and carious teeth with different frequencies ranging from 0.01 Hz to 10 MHz. The presented study is supported by the scanning electron microscopy (SEM) and the Energy Dispersive X-ray spectroscopy (EDX) test for analysis of the teeth' structure and detect the elements and chemical characteristics of the teeth. The Xray and imaging tests are done using dental radiography X-ray equipment in Al-Karkh General Hospital with the help of dentists. The results of the study showed that with the wide spectrum of frequencies, the electrical impedance averaged value for carious teeth is less than its value in the healthy teeth since the impedance real part is (3.63E+03 to 2.59E+06) Ω and (82.567 to 1.27E+05) Ω for the healthy and carious teeth respectively, with increasing in the frequency range (1.00E-02-8.89E+06) Ω and reducing the phase shift. Since healthy teeth have fewer chemical elements than carious teeth, the EDX test showed the chemical elements of the tooth, including Antimony, Calcium, Phosphorous, Carbon, and Chlorine, in different concentrations. The promising results show that the proposed method is sufficient and reliable to differentiate the carious in early stages, giving a chance to recover and maintain the teeth' health.
