Title: Root point position detector
Inventor: KOBAYASHI CHIHIRO
IPC: A61C19/04
Filed: 1990-07-13
Abstract: PURPOSE:To dispense with complicated calibration while enabling accurate detection of a position of a root point by detecting the position of the root point depending on a deviation in phase or waveform between a voltage waveform and a current waveform. CONSTITUTION:Load current flowing between a measuring electrode 2 and a oral cavity electrode 3 is detected in the form of a voltage of a measuring electrode 2 and an equivalent circuit between both the electrodes 2 and 3 is considered as parallel circuit of a resistance and capacitor. So, when a measuring voltage waveform A is a sine wave, phase of load current waveforms B1 and B2 vary with a capacity of a capacitor though becoming the same sine waves. As a result, when a capacity component of an equivalent impedance increases as the tip 2a of the electrode 2 approaches near a root point, a deviation in phase of the load current waveform grows with respect to a waveform A and a current waveform C2 of a phase comparator circuit 6 becomes larger than the C1 according to a phase difference therebetween. Thus, display contents, for example, a deflection of a pointer of a display section 7 increases accordingly thereby indicating that the root point is reached by the deflection.
