Description

Technical Field

[0001] The utility model relates to the technical fields of oral medical practitioner (assistant) skills examination tools and clinical teaching, and particularly relates to a simulation resin tooth used in conjunction with pulp opening treatment in oral skills examination. Background Art

[0002] Endodontic and periapical diseases, including pulp diseases and periapical diseases, are extremely common oral diseases. Their main clinical manifestations include toothache (hot and cold pain and night pain), sensitivity, gum swelling, etc., which seriously affect the quality of life of patients. The standard treatment is root canal treatment, and the first step of root canal treatment is pulp opening. It can be seen that pulp opening treatment is crucial and frequently used in the treatment of oral diseases. Therefore, pulp opening treatment has become a compulsory item in the oral medical practitioner (or assistant) skills examination and is also a basic skill that every oral doctor should master.

[0003] In the pulp opening treatment during the examination, candidates are required to uncover the entire pulp chamber roof and find the root canal orifice. And there are several situations in the examination that will be rated 0 points, such as: 1. Incorrect tooth position; 2. Perforation of the lateral wall of the pulp chamber; 3. Perforation of the pulp chamber floor. The evaluation for these situations needs to be cautious. Incorrectly rating 0 points (rating 0 points when it should not be given) will directly affect the candidate's examination results and is irresponsible to the candidate; while omitting 0 points (not giving 0 points when it should be given) is irresponsible for the patient's life and health. Therefore, the evaluation of these items should be intuitive and accurate.

[0004] In the oral medical practitioner skills examination, the commonly used tooth models are simulation resin teeth and extracted teeth. However, extracted teeth have many deficiencies. For example, they are prone to decay and emit a foul smell after being placed for a long time, and the enamel is prone to crack under high-speed turbine drilling after being treated with disinfectant, which may not only affect the examination results but also cause injury to candidates during operation. Currently, resin teeth are commonly used in the examination, but resin teeth are not perfect either. For example, it is impossible to visually distinguish whether there is a perforation in the pulp chamber floor, and it is also difficult to judge whether the candidate has found the root canal orifice.

[0005] In summary, to ensure the objective accuracy of the oral medical practitioner (or assistant) skills examination results and at the same time ensure that patients receive standardized and effective treatment, it is particularly important to improve the structure of the simulation resin tooth used in pulp opening treatment in the oral medical practitioner (or assistant) skills examination. Content of the Utility Model

[0006] In view of this, the utility model provides a simulation resin tooth used in conjunction with pulp opening treatment in oral skills examination to solve the problems of being unable to visually distinguish whether the pulp chamber is perforated and being difficult to judge whether the candidate has found the root canal orifice.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] A simulated resin tooth for use in endodontic treatment in an oral skills exam, including a simulated resin tooth body having a pulp wall and a root canal. The pulp wall consists of multiple parts that together enclose a pulp chamber. A contour coating is provided on the surface of each inner wall of the pulp wall. The root canal is filled with a fluid, and the orifice of the root canal is closed.

[0009] To better implement the above technical solution, optionally, the materials of the simulated resin tooth body and the pulp wall are both methyl methacrylate.

[0010] Optionally, the material of the contour coating is polyurethane resin.

[0011] Optionally, the thickness of the contour coating is 0.3 - 0.5 mm.

[0012] Optionally, the fluid is silicone oil, aqueous gel or calcium hydroxide paste.

[0013] Optionally, the contour coating includes a pulp top wall coating, a pulp bottom wall coating, a mesial wall coating, a distal wall coating, a buccal wall coating and a palatal wall coating.

[0014] Optionally, a marking body is provided in the simulated resin tooth body directly below the pulp bottom wall.

[0015] Optionally, the root canal includes a palatal root canal, a mesial buccal root and a distal buccal root.

[0016] Advantages of the present utility model:

[0017] When using the simulated resin tooth of the present utility model for the exam, after the exam, the review teacher can directly observe the contour coating to quickly and accurately judge whether the candidate has uncovered and completely uncovered the pulp top wall, check the wear condition of other walls of the pulp, and determine whether the pulp bottom wall is perforated. Also, by checking whether there is fluid overflow at each root canal orifice, it can be determined whether the candidate has found the positions of each root canal orifice. This simulated resin tooth can assist the review teacher to objectively and accurately evaluate the practical operation ability of the candidate, reduce the review difficulty and blindness of the review teacher, and effectively improve the accuracy and efficiency of the review.

[0018] In the simulated resin tooth of the present utility model, a marking body is provided directly below the pulp bottom wall coating. When the candidate exposes the marking body, it indicates that the candidate has penetrated the pulp chamber floor during the endodontic process, and a zero score can be directly judged. Adding the marking body can accurately judge the mistakes in the candidate's operation and further improve the comprehensiveness and accuracy of the exam evaluation. Description of the Drawings
