However, although the above-mentioned drug has a disinfecting action, it is highly toxic, and its pseudo-harmful action on living tissues such as causing burns and the like in the tissues around the teeth cannot be ignored, and since the drug is a liquid, After being injected into the root canal, it flows out before sufficient disinfection in the root canal, and after the outflow, there is a problem that a pseudo-harm effect is exerted on surrounding tissues.

In order to solve the above-mentioned problems, calcium hydroxide (Ca (OH) 2 ) having relatively low toxicity is used as a powder, and purified water or a synthetic polymer solution such as polyethylene glycol is used as a liquid, and the powder is used. A disinfectant has been proposed which is kneaded with a liquid agent and applied as paste-like kneading mud to the affected area. However, the kneading mud using purified water as a liquid is not viscous, the filling operation of the kneading mud is difficult, and the kneading mud has poor fluidity, so that the kneading mud should be filled in every corner of the filling place. There is a problem that you can not. On the other hand, the kneaded mud kneaded by using a synthetic polymer solution such as polyethylene glycol as a liquid agent has a problem that it cannot be packed tightly because its viscosity is too high. In order to solve the above-mentioned problems, the applicant of the present patent has proposed, in JP-A-4-95007, to knead an aqueous solution containing sodium chondroitin sulfate with the powder. This kneading agent has good operability, and no separation of powder liquid was observed in the short-term storage, for example, within 30 days, but it was separated after a long-term storage, for example, 3 months or more. It is difficult to distribute and sell the premix type, which is packed in the market and sold. Furthermore, since sodium chondroitin sulfate is expensive,
There are also cost issues.

The powder used in the present invention contains 90% by weight or more of calcium hydroxide and is a component mainly for preventing infection in the root canal and disinfecting the infected root canal after pulp extraction. When the root apex is open, it is a component capable of calcifying and blocking the root apex. The purity of calcium hydroxide is preferably 90% by weight or more. If it is less than 90% by weight, many impurities are contained and the drug effect is lowered, so that it cannot be used. The purity of calcium hydroxide described in the Japanese Pharmacopoeia is defined as "90% or more", and it can be preferably used as it is as the powder of the present invention. Other components may be added to the powder of the present invention, but an X-ray contrast agent such as barium sulfate is not particularly necessary for the therapeutic procedure. The aqueous solution used in the present invention contains methyl cellulose, and the aqueous solution may further contain propylene glycol and the like.
The content of methyl cellulose in the aqueous solution is preferably 1 to 8% by weight. If it is less than 1% by weight, the viscosity tends to be insufficient, and if it exceeds 8% by weight, the viscosity tends to be too high and the fluidity tends to deteriorate. Furthermore, the viscosity of methyl cellulose is 30 to 2000.
Centistokes are preferred. If it is less than 30 centistokes or exceeds 2000 centistokes, the operability of the mixed paste tends to deteriorate. Although 50% by weight or less of the total amount of propylene glycol can be contained in the aqueous solution, if the content exceeds 50% by weight, the compatibility with methyl cellulose tends to be poor. Methylcellulose is water-soluble and has a dispersing action, and when mixed with a powder agent containing calcium hydroxide as a main component, the mixed paste has good fluidity and is stable and does not separate for 3 months or more. Propylene glycol is a viscous liquid and has good operability when mixed with calcium hydroxide, and also has antibacterial properties and diffusibility. Calcium hydroxide is also bacteriostatic,
Even if mixed with an aqueous solution containing methylcellulose, molds and the like are unlikely to occur during storage, but the risk is remarkably reduced when propylene glycol is contained. The diffusivity of calcium ions by the mixed paste of the powder and the aqueous solution is also smoother in the mixed solution containing propylene glycol than in the aqueous solution containing methylcellulose, and the therapeutic effect is also improved.

The ratio of the powder agent to the liquid agent in the present invention is 60 to 150 parts by weight, preferably 70 to 120 parts by weight, with respect to 100 parts by weight of the powder agent containing 90% by weight or more of calcium hydroxide. This is because if it is less than 60 parts by weight, the paste is too hard and the fluidity is poor, and if it exceeds 150 parts by weight, the amount of the aqueous solution is too much and the separation becomes easy.

The tooth root canal disinfectant of the present invention is excellent in preventing infection in the root canal after pulp extraction and disinfecting the infected root canal.
And there is no pseudo-harm effect on the living body. In addition, since this drug can impart appropriate viscosity, it can be stably present at the target site for a long period of time, has excellent therapeutic effects, and is rich in operability and moderate fluidity, so it has a complex root. It is possible to tightly fill every corner of the tube. Furthermore, the mixed paste does not separate even during long-term storage, and can be distributed and sold as a premix type that can be used immediately. Further, by containing propylene glycol, the possibility of putrefaction during long-term storage can be significantly reduced, the diffusivity of calcium ions can be increased, and the therapeutic effect can be improved.

As a result, the amount of 50 parts by weight of the aqueous solution is 3 for 100 parts by weight of the powder.
After 0 days, there was considerable resistance when extruding and it was impossible to extrude. Further, when the amount of the aqueous solution was 200 parts by weight with respect to 100 parts by weight of the powder, the paste extruded due to too much aqueous solution was not viscous and was difficult to use. On the other hand, 60 parts by weight of the aqueous solution,
The parts by weight, 90 parts by weight, 120 parts by weight and 150 parts by weight could be smoothly extruded and used without separation until 90 days passed, and the paste had appropriate viscosity and fluidity.

85 parts by weight of the aqueous solution and 85 parts by weight of the aqueous solution were mixed with 00 parts by weight and filled in syringes. This was inserted into agar containing a phenolphthalein indicator with the opening of the syringe facing downward, and the diffusivity of calcium ions was examined after 24 hours. When the pH is biased toward the alkaline side due to the diffusion of calcium ions, the phenolphthalein in the agar turns red, so the distance from the opening of the syringe to the end of the color change was measured and the diffusivities were compared. The results are shown in Table 1. In addition, propylene glycol 50% by weight
