Method for testing manual stainless steel K file

Abstract

The invention discloses a method for testing a manual stainless steel K file. The method comprises the following steps of performing root canal preparation on the manual stainless steel K file serving as an experiment object by a crown root direction preparation method through a 15% calcium zinc chloride solution; in a foot canal preparation process, alternately washing machinery through 3% hydrogen peroxide and 0.9% normal saline before and after replacement of the machinery at each time; dehumidifying and drying a root canal, introducing calcium hydroxide paste into the root canal through a spiral conveyer, and temporarily sealing the root canal through interacanal for 7-10 days. The method has the beneficial effects that the pain incidence during the root canal treatment can be reduced; the pain reaction degree is equal to the conventional pain reaction degree; the method deserves to be clinically popularized and used.

Description

technical field [0001] The invention relates to a method for conducting a test experiment with a stainless steel K file, specifically, a method for conducting a test experiment with a stainless steel K file. Background technique [0002] Root canal therapy is an effective method for treating pulp disease and periapical disease, and root canal preparation is the key to the success of root canal therapy. Root canal preparation is to remove the infected material in the root canal through mechanical cutting, and at the same time, on the basis of the original root canal direction, the root canal is formed into a relatively regular tapered lumen with a narrow mouth and a large mouth, so as to facilitate the free entry of irrigation fluid Root canal, remove the cut material out of the root canal, and the tapered root canal also facilitates root canal filling, so as to obtain a good root canal seal and create conditions for healing. In order to achieve this goal, not only does the ...

Problems solved by technology

At present, the commonly used root canal preparation instruments are mainly divided into two types: one is stainless steel instruments, which have a high rate of clinical application, but based on their steel characteristics, the instruments have high hardness, low elasticity, and relatively weak cutting ability, which is time-consuming and laborious.

At the same time, when preparing the root canal, it often causes complications such as steps, open apical foramen, root canal deviation and even root canal wall perforation.

After root canal preparation, the original conical cavity becomes unsmooth, affecting the smooth entry of root filling materials, reducing the quality of root canal filling and the effect of root canal treatment
