TECHNICAL FIELD OF THE INVENTION
The present invention electrically connects display means and detection means of a dental diagnostic device such as a root canal length measuring device, a periodontal pocket depth measuring device, a pulp diagnostic device, and an ultrasonic scaler having a root canal length measuring function. The present invention relates to a dental care device that can be suitably implemented for connection.
[0002]
[Prior art]
For example, root canal treatment in endodontics requires accurate measurement of root canal length in order to completely expand, clean, disinfect and fill the root canal. In addition, it is not preferable to stimulate the apical periodontal tissue with a reamer or file over the apical foramen during treatment, and the insertion of the instrument becomes insufficient due to fear of such apical periodontal tissue stimulation. It is not preferable to leave a space in the apical root canal that cannot be cleaned and disinfected, thereby leaving a cause of poor post-treatment. Therefore, when performing root canal treatment, in order to determine the exact working length in advance, it is necessary to measure the root canal length, as a device for measuring this root canal length, a reamer inserted into the root canal, The root canal length is detected based on the fact that the electrical resistance between the oral electrode and the oral mucosa shows a substantially constant value (6.5 kΩ) when the tip of the reamer reaches the tooth root surface. An electrical root canal length measuring device is used.
[0003]
In such a root canal length measuring device, an oral electrode and a measuring electrode gripped by a clip connected to the reamer or the like are connected to a device main body by a lead wire, and the main body has a resistance between the oral electrode and the measuring electrode. A meter, which is a display means for displaying a value, is provided. When measuring the root canal length using such a root canal length measuring device, insert the tip of a reamer, which is a measuring electrode, into the root canal with the hook-shaped oral electrode hooked on the lower jaw of the patient. Then, when the indicated value of the meter approaches 6.5 kΩ, it is determined that the tip of the reamer has reached the apical periodontal tissue, and the depth at that time is defined as the root canal length.
[0004]
