Technical Field

The present invention relates to a root canal treatment device, and more particularly to a root canal treatment device including: the root canal of the tooth is flushed, and the flushed root canal is filled with a filler, and the flushing and filling of the root canal can be performed simultaneously.

Background

In 1967, Kakeyash et al demonstrated for the first time that bacteria were the main cause of inflammation of dental pulp by sterile mice, and then discovered by inflammatory reaction that biofilm and necrotic tissue, which are bacteria constituting colonies, were the main cause of inflammatory reaction inside the root canal. Therefore, when determining the success or failure of nerve treatment, it is important to completely remove bacteria and necrotic tissue present in the root canal and prevent the proliferation thereof.

This endodontic procedure generally includes three steps: root canal formation, root canal irrigation, root canal filling.

The root canal flushing process is performed after the first removal of the rotten nerve using a root canal file (endodontic file), which is a process having an important influence on the success rate of nerve treatment since it is essential to remove infectious microorganisms.

However, even if the contaminants are flushed to the level 0 (score 0) (the residual amount is less than 10% in a designated portion in the root canal), nutrients are supplied to the residual bacteria and there is a risk of proliferation of the bacteria if the root canal is not completely sealed. Accordingly, a process of sealing the flushed root canal with the filler is performed.

In the related art, PUI (passive ultrasonic irrigation) is known, and after filling an irrigation liquid in a root canal, an oscillating ultrasonic tip (tip) is inserted to irrigate the root canal.

In addition, in the prior art, a method of injecting a filling material into a root canal using a syringe needle (syringe-needle) is known for filling the root canal, but the injection of the filling material into a tooth tip part is limited because of the high viscosity of the filling material and resistance to air existing in the root canal.
