た。Conventional paste-like hardening filling materials are soft and fluid, but it is difficult to reliably fill and seal the root canal up to the tip, and if the seal inside the root canal is incomplete, it may leave a gap at the apex. This has disadvantages such as the invasion of bacteria and foreign substances and the creation of new apical lesions. In addition, glue materials such as zinc oxide Nisinol cement seal the root canal well immediately after hardening in the root canal, but because the hardened material has no elasticity, it cannot be repeatedly heated with hot or cold water in the oral cavity. The impact causes detachment from the tooth structure,
There were problems such as the gaps becoming starting points for new lesions.

That is, for example, by telomerizing a fluorine-containing monomer in an alcohol such as methyl alcohol or ethyl alcohol, a fluorine-containing oligomer having an OH group at the end of the molecular chain can be obtained. The monomer [

注入が困難になる。In this case, the fluorine-containing oligomer R2 of the simple substance [I] is two or more selected from vinylidene fluoride, vinyl fluoride, trifluoroethylene, chlorotrifluoroethylene, tetrafluoroethylene, and hexafluoropropylene. A fluorine-containing oligomer composed of a fluorine-containing monomer is preferable, and the fluorine-containing oligomer constituting the ester moiety of monomer [I] is a binary or ternary one of the above-mentioned fluorine-containing monomers. Fluorine-containing oligomers, which are copolymers, are particularly preferably used. The molecular weight of the fluorine-containing oligomer used is 200 to 1,500. If the score is 200 or less, the product after polymerization and curing is brittle and easily peels off due to thermal shock.
If it exceeds 00, the viscosity becomes high and the fluidity deteriorates, making it difficult to inject into the root canal.

重Ｇ部以上になると流動性が悪くなるためである。Further, the added calcium phosphate and/or hydroxyabalate has the ability to promote healing of bony scars at the apical foramen site, and the amount added is 30 to 60 parts by weight per 100 parts by weight of monomer [I]. Parts by weight, preferably 40 to 50 parts by weight, are suitable. That is, if the amount added is too small, the bony healing effect will be small, and if it is too large, the fluidity will deteriorate, resulting in poor root canal sealing properties. Also, these things themselves have
One or more X-ray contrast agents selected from barium sulfate, zinc sulfide, zinc oxide, zirconium oxide, triform, etc., which have contrast properties and are used as an X-ray contrast agent to confirm the sealing state in the root canal. For 100 parts of monomer [■],
It can be added in a range of 10 to 50 parts. 10
This is because the effect decreases below 50 parts by weight.
This is because if it exceeds the heavy G part, the fluidity deteriorates.

なるためであり、１０重量部以上でも効果が増えないか
らである。As an antibacterial agent, chlorhexidine is used as a monomer [I] 100
It can be added in an amount of 1 to 10 parts by weight, preferably 2 to 6 parts by weight, based on the heaviest part. This is because if the amount is less than 11 parts by weight, the effect will be reduced, and if it is more than 10 parts by weight, the effect will not increase.

根管内で１０分以内に重合固化せしめることができる。The root canal filling material of the present invention is a root canal filling material made by blending these materials, and is in the form of a paste. For this reason, in clinical use, immediately before use, a small amount of radical polymerization initiator, preferably 1 to 5% by weight, is added, mixed and injected into the root canal. It can be easily injected with the help of the so-called single corne method.
injection is easy. As the radical polymerization initiator, tri-n-butylborane oxide, organic peroxides such as benzoyl peroxide (BPO), aromatic tertiary amines such as dimethyl para-toluidine, sodium para-toluenesulfinate, etc. can be used. ,
It can be polymerized and solidified in the root canal within 10 minutes.
