Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to display means for dental diagnostic equipment such as a root canal length measuring device, a periodontal pocket depth measuring device, a dental pulp diagnostic device and an ultrasonic scaler with a root canal length measuring function. The present invention relates to a dental treatment apparatus that can be suitably implemented to electrically connect with a detection means.

[0002]

2. Description of the Related Art For example, root canal treatment in endodontics is
Accurate measurement of root canal length is necessary for complete root canal expansion, cleaning, disinfection and root canal filling. In addition, it is not preferable to stimulate the apical periodontal tissue with a reamer or a file over the apical foramen during the treatment, and the instrument may be insufficiently inserted due to such stimulation to the apical periodontal tissue. However, it is not preferable to leave a space that is not cleaned and disinfected in the root canal of the root apex and leave the cause of poor post-treatment. Therefore, when performing root canal treatment, it is necessary to measure the root canal length in order to determine an accurate working length in advance.As a device for measuring this root canal length, a reamer inserted into the root canal, The root canal length was detected based on the fact that the electrical resistance value between the oral electrode that was in contact with the oral mucosa and the tip of the reamer reached the root surface of the tooth showed an almost constant value (6.5 kΩ). An electric root canal length measuring device is used.

In such a root canal length measuring apparatus, an oral electrode and a measuring electrode gripped by a clip connected to the reamer are connected to a device body by a lead wire, and the oral electrode and the measuring electrode are connected to the body. A meter, which is a display means for displaying the resistance value between them, is provided. When measuring the root canal length using such a root canal length measuring device, insert the tip of the reamer, which is the measuring electrode, into the root canal with the hook-shaped oral electrode held on the lower jaw of the patient. When the indicated value of the meter becomes around 6.5 kΩ, it is judged that the tip of the reamer has reached the apical periodontal tissue, and the depth at that time is taken as the root canal length.

[0004]
