管充填材と呼ばれるものもある。Conventional technology Root canals are used to protect and treat root-end wounds by inserting root canal filling material into the root canal system, which has become a void after pulp extraction or infected root canal treatment in dental treatment. Perform filling operation. Therefore, these procedures are the most frequent (and important) treatment methods in dental clinical practice as a preliminary step to dental treatment. Conventionally, various root canal filling materials have been used for these procedures. Therapeutic materials include glue threads (e.g. calcium hydroxide glue), or solid materials that mainly provide physical sealing (e.g. gutta percher points).Solid root canal filling Even when using a sealer, in order to securely seal the root end, it is necessary to perform combined root canal filling with a type of sealer called a sealer. There is also a hardened solid (cement type) root canal filling material that hardens after a certain period of time.

Therefore, a mixing operation is required, and if mixing is insufficient, it is thought that the ability to reach the root tip will be poor.

用組成物を提供せんとするものである。Means to Solve the Problem In recent years, tetracalcium phosphate and tricalcium phosphate, which are known as inorganic components of living hard tissues such as teeth and bones, have been used in dental implants, artificial bones, etc. due to their excellent biocompatibility. However, the present inventors have conducted various studies on the effects of such tetracalcium phosphate and tricalcium phosphate on the living body, especially on the dental pulp and tissues surrounding the root tip. We have discovered that root canal filling materials containing tricalcium phosphate as the main ingredient have high clinical application value, and we have found that tetracalcium phosphate and/or calcium phosphate can be used as shelving materials, X-ray contrast materials, antibacterial materials, etc. The purpose is to provide a paste-like root canal filling composition by blending ingredients.
