Method for measuring tooth root canal therapy working length

Abstract

The invention belongs to the technical field of medical parameter measurements, and relates to a method for measuring a tooth root canal therapy working length. According to the technical scheme, the method comprises the following steps: when shooting an X-ray dental film, placing an X-ray radiopaque straight-line reference with a set length between a target tooth and an X-ray image plate and carrying out projection; calculating the tooth root canal therapy working length through measuring the image length of the shot dental film and the image length of the reference, and determining the tooth root canal therapy working length; and obtaining a formula as follows: the root canal therapy working length H of the target tooth is equal to the product of the set length L of the straight-line reference and the division result of the X-ray image length M of the root canal therapy working length of the target tooth and the X-ray image length N of the straight-line reference, namely H=L*M / N through calculation, so that measurement of the root canal therapy working length H of a to-be-treated tooth is achieved. By adopting the method, accurate measurement on the tooth root canal therapy working length is achieved; the measurement technology is scientific and reasonable; the measurement result is accurate; the measurement environment is friendly; and application and operation are flexible and convenient.

Description

Technical field: [0001] The invention belongs to the technical field of medical parameter measurement, and relates to a technical scheme for measuring the working length of root canal treatment in the treatment of stomatological diseases, in particular to a method for measuring the working length of tooth root canal treatment, which is used for the technical data of clinical treatment of dental diseases and parameter determination. Background technique: [0002] At present, root canal therapy is the most effective treatment for pulpitis and apical periodontitis in the clinical work of stomatology. It is very important to determine the accurate working length in the usual root canal treatment process, which is the key to the success or failure of root canal treatment. one of the important factors. In the prior art, the measurement of working length of root canal treatment is usually carried out by electric measurement method, X-ray irradiation method of inserting metal wire ...

AI Technical Summary

Problems solved by technology

In the prior art, the measurement of working length of root canal treatment is usually carried out by electric measurement method, X-ray irradiation method of inserting metal wire in the root canal and hand feeling method. Digital X-ray dental film has been widely used in clinical stomatology However, these methods are generally difficult to operate, take a long time to operate, and the patient is uncomfortable. There is also the risk of the instrument slipping and entering the airway and esophagus. Sometimes the error is relatively large, which induces operational errors, causes conflicts between doctors and patients, and even causes medical accidents.
