Embodiment approach 1

[0053] 【Structure of probe for side branch detection】

[0054] Since it is necessary to repeatedly detect the condition of the side branch e when the measurement electrode 10 is inserted into the root canal 22, the side branch detection device 100 described above requires troublesome work. In view of the above circumstances, the side branch detection probe 200 according to Embodiment 1 of the present invention ( Figure 7 ) Detect the condition of side branches e (presence or absence of side branches e and their position in the axial direction of the root canal) after insertion of the root canal 22 .

[0055] Such as Figure 7 As shown, the side branch detection probe 200 includes a measurement electrode set 210, and the measurement electrode set 210 includes a plurality of measurement electrodes 220 (220) inserted into the root canal 22. 1 to 220 5 ). That is, the side branch detection probe 200 includes a plurality of measurement electrodes 220 extending to different pos...

Embodiment approach 2

[0083] Embodiment 2 will be described while referring to differences from Embodiment 1. FIG.

[0084] The side branch detection probe 400 according to Embodiment 2 ( Figure 9 ) is different from Embodiment 1 in that, in addition to the position of the side branch e in the axial direction of the root canal, the position of the side branch e in the direction around the root canal axis can also be detected as the condition of the side branch e.

[0085] 【Structure of probe for side branch detection】

[0086] Such as Figure 9 As shown, the probe 400 for side branch detection includes a multilayer measuring electrode set 410, and the multilayer measuring electrode set 410 includes a conductor 431. The conductor 431 provides the surface of a hollow cylindrical flexible material 440, and is arranged in the root canal axis Y and separated in the direction α around the root canal axis ( Figure 10 ). Here, the multilayer measuring electrode group 410 includes circumferential meas...

Abstract

Provided is a lateral branch detection probe 200 whereby the condition of a lateral branch can be detected merely by inserting the lateral branch detection probe 200 to a root apex. A lateral branch detection probe (200) detects, after insertion thereof into a root canal of a tooth, the presence / absence of a side branch and the position of the side branch in the root canal axial direction, the lateral branch detection probe (200) being provided with a plurality of measurement electrodes (220) extending to different positions in the root canal axial direction (Y) at predetermined intervals, themeasurement electrodes (220) each being covered by an insulator (223) except at one end part thereof, and the other end parts being a measurement terminal group (227) capable of connecting to a detection power source on a detection device side.

Description

technical field [0001] The present invention relates to techniques for detecting side branches extending from root canals into teeth during dental diagnosis or treatment. Background technique [0002] When the surgeon performs dental treatment, it may be necessary to remove the pulp or affected dentin inside the root canal. Figure 13 A cross-sectional view of a tooth is shown. Figure 13 Among them, a represents the tooth, b represents the root canal, c represents the apical foramen, d represents the gingiva, e represents the side branch extending from the root canal to the periodontal space h, f represents the alveolar bone, g represents the reference point of the tooth, h Indicates the periodontal space. The operator measures the distance from the tooth measurement reference point g to the apical foramen c, and then removes the pulp, etc. (nerves, dentin after bacterial infection, or foreign objects in the root canal) corresponding to the distance in the root canal b. Th...
