【発明の詳細な説明】
本発明は歯科治療の分野において、根管充填材として用

歯科治療の分野における根管充填操作は、抜髄後あるい

より閉塞し、根尖部創傷の保護、回復をはかり、操作後
の歯の保存を目的とする処置である。Root canal filling operations in the field of dental treatment involve sealing the root canal cavity after pulp extraction or root canal treatment by applying a root canal filling material composition to protect and recover the apical wound. This treatment aims to preserve teeth.
従来から、このような処置には根尖部に対する治療促進

剤根管充填材は、組織の治療は期待できるが、根管内で
硬化しないため長期間の適用には不安がある。又、固形
根管充填材は物理的に閉塞するのみであり、組織の治癒
は期待できない。Traditionally, such treatments have included non-hardening glue root canal filling materials (e.g., formalin-based), hardening glue root canal filling materials (for example, formalin-based), and hardening glue root canal filling materials (for example, formalin-based) for the purpose of promoting treatment at the root apex or treating bony scars. For example; zinc oxide-eucinol system), or solid root canal filling materials for the purpose of physical occlusion (e.g. Nigata percher points). Among these, non-hard glue root canal filling materials can be expected to treat tissues, but there are concerns about long-term application because they do not harden within the root canal. Moreover, solid root canal filling materials only physically occlude, and tissue healing cannot be expected.
これに対して、練和後成る一定の時間経過して根管内で
硬化する硬化性糊剤根管充填材は、組織の治癒及び根管

腔の存在を皆無にすることが期待できる。On the other hand, a hardening paste root canal filling material that hardens within the root canal after a certain period of time after kneading can be expected to achieve both the objectives of tissue healing and root canal occlusion. Furthermore, when used together with a solid root canal filling material as a sealer, it is expected that the solid root canal filling material, such as gutta percher points, will adhere to the root canal wall and the presence of dead space will be completely eliminated.

ない。Conventionally, this curable glue root canal filling material has been made with zinc oxide as its main component and mixed with nisinol.
O-nisinol cement has been widely used. However, the components of this cement are completely different from those of teeth, and the material is not necessarily satisfactory in terms of tissue affinity.

は、硬化物の崩壊率が高く、根管充填材としての要求性
能を満足しないという問題がある。In order to solve this problem, a hardening glue root canal filling material has recently been proposed in which hydroxyapatite, which is similar to the main component of bones and teeth, is added to powder and mixed with guaiacol. . (For example; JP-A-62-'2554
However, these known techniques have a problem in that the disintegration rate of the cured product is high and does not satisfy the required performance as a root canal filling material.

材として高い性能を有する。The present invention is composed of a powder mainly composed of calcium phosphate powder, which has a composition similar to the main components of bones and teeth like hydroxyapatite, a water-soluble organic acid, a water-soluble polyhydric alcohol, and an X-ray contrast agent. , relates to a one-paste type root canal filling composition that hardens within the root canal. The root canal curable paste 1 of the present invention is a root canal filling material composition that does not harden in a sealed container but hardens by reacting with body fluid or intramedullary fluid that enters from the root apex and dentinal tubule after being filled into the root canal. It has excellent tissue affinity, low disintegration rate of the cured product, and high performance as a root canal filling material.
