ROOT APEX POSITION DETECTION METHOD |
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.
