Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Such as figure 1 As shown, the root canal exploration method of the present invention is used to judge whether the root canal preparation is insufficient, and it specifically includes the following steps:

[0025] S1. Provide isolated teeth, dredge and expand the 2 / 3 root canal crown, and observe whether the root canal is compatible with the prepared shape.

[0026] S2. Dredge the apical 1 / 3 of the root canal and measure its length.

[0027] Among the...

Abstract

The invention provides a root canal probing method. The method comprises the following steps: S1. providing an isolated tooth, carrying out dredging enlargement treatment on 2/3 a crown of a root canal, and observing whether the root canal is adaptable to a prepared form or not; S2. carrying out dredging treatment on 1/3 a root tip of the root canal, and carrying out length measurement; S3. enlarging the 1/3 root tip of the root canal to a measurement dead point; S4. probing to judge forms of all directions of the root canal at the dead point; S5. continuing to enlarge the root canal, probing the forms of all the directions of the dead point, and stopping enlarging a root canal wall in a corresponding direction when the condition that a small-step-similar structure is present on the root canal wall is probed; S6. carrying out root canal preparing on the root canal wall in the corresponding direction when the condition that the small-step-similar structure is present on the root canal wall is not probed. According to the root canal probing method provided by the invention, whether root canal preparation is subjected to insufficient or excessive problems or not can be judged through probing internal dead point and diameter conditions of the root canal, and then, an instruction is provided for root canal preparation.

Description

technical field [0001] The invention relates specifically to a root canal exploration method for judging whether the root canal preparation is insufficient. Background technique [0002] At present, in root canal preparation, we often face the problems of under-preparation and over-preparation. For example, the diameter of a root canal with a circular diameter is 0.25mm when it is 1mm away from the apical foramen. When this point is prepared with a file below No. 25 (including No. 25), the root canal has not been enlarged, and vice versa. suspicion of underpreparation. However, when expanding to No. 30, there will be a "slight" and similar step-like change at the tip of the stop. At this time, use a No. 6 file to pre-bend the tip within 1mm and the pre-bend angle does not exceed 45 degrees, and conduct a circular probe along the stop. The above situation will be found. The above situation means that the cross-section of the dead point has been expanded by 100%. If it is e...
