Usefulness of AC-impedance spectroscopy technique in occlusal caries detection – own investigations
Journal Title: Current Issues in Pharmacy and Medical Sciences - Year 2013, Vol 26, Issue 4
Abstract
Exact caries detection and monitoring over time are important in modern clinical caries management. Especially the detection before cavitation occurs and the control of initial lesions are of significance because an accurate diagnosis can reduce the need for drilling and filling. Among many techniques, impedance spectroscopy technique is one of the proposed. The aim of the study was to determine dental caries clinically and characterize its bio-impedance to gain detailed information about the progression of the process. Human extracted permanent premolars and molars were used in this in-vitro experiment. The teeth were unrestored and undamaged, except of caries. Their occlusal surfaces were examined by dentists according to Universal Visual Scoring System and assessed with CarieScan PRO™. The statistical analysis of obtained results revealed that clinical examination and AC-impedance spectroscopy measurements showed differences in impedance depending on changes and stages in caries progress. Preliminary results from this research indicate that the device using AC-impedance spectroscopy may be a useful additional aid for caries diagnosis together with clinical examination.
