    摘要： Methods of detecting a root apex position of a root canal of a test tooth, including applying a plurality of types of measurement signals to one of the measurement electrode and the mouth electrode; sequentially applying each of the plurality of types of measurement signals to one of the measurement electrode and the mouth electrode; sequentially detecting a plurality of electrical characteristic values between the measurement electrode and the mouth electrode based on each of the applied measurement signals using a detection unit. The methods further include obtaining a test tooth data group; comparing the test tooth data group with a plurality of model tooth data groups; detecting whether one of the plurality of model tooth data groups is in a predetermined relationship with the test tooth data group; and displaying the detected result.

    摘要： A tooth mobility measuring apparatus of this invention includes an impact mechanism which injects or sucks a fluid to apply an impact to a tooth, a sensor which detects the displacement state of the tooth which is moved by the impact force from the impact mechanism, and a tooth mobility calculation mechanism which calculates the tooth mobility of the tooth on the basis of the output signal from the sensor. The displacement state of the tooth is measured without touching the tooth.

    摘要： Root apex position model data associated with electrical characteristic values between a measurement electrode and a mouth electrode in a state in which the distal end of the measurement electrode is located at a root apex position of a root canal is stored in a storage unit. A power supply applies measurement signals of 500 Hz and 2 kHz between the measurement electrode and the mouth electrode. Two different current values flowing between the measurement electrode and the mouth electrode are detected. These current values are compared with the root apex position mode data stored in the storage unit. If the root apex position data includes any data which coincides with the current values, it is detected that the distal end of the measurement electrode is located at the root apex position.
