Sažetak
The match between an in vitro model and actual measurement in vivo of root canal length was tested. Elements of a three-element electrical equivalent circuit have been obtained and their frequency dependence determined by measuring impedance in the range from 100 Hz to 1 MHz on a model and in vivo. It has been shown that there is a coincidence between the model and in vivo measurement only at lower frequencies when total impedance is determined by the impedance of the electrode-electrolyte double layer. At frequencies above 1 kHz the physical model does not behave, in electrical terms, as in vivo measurement. Therefore, due caution is required when drawing conclusions on apex locator accuracy based on model measurements.
