Description of the Related Art A root canal filling point of an endodontic material and a root canal filling sealer are materials that are placed in a living body even though they are inside a root canal, and come into contact with tissue around a root through an apical hole. Considering the situation and the case of extravasation from the apical foramen, the problem of biological harm is important. Among the gutta-percha fillers used as root canal fillers, which vary depending on the product, some 20% gutta-percha and about 70% zinc oxide, as well as several% of fillers, contrast agents and plastics Many contain agents. On the other hand, many sealers have been prescribed for filling the glue root canal, but the most common and frequently used sealer is a zinc oxide eugenol-based sealer, which contains 42% zinc oxide in powder,

本発明を更に詳細に説明する。The hydroxyapatite used in the present invention has a chemical formula of Ca 10 (PO 4 ) 6 (OH) 2 , is powdery, has a density of 3.16 g / cm 3 and is slightly soluble in pure water. , Exhibits weak alkalinity. It dissolves in acids but hardly dissolves in alkalis. It is similar to the main components of teeth and has good biocompatibility. It is commercially available and the amount used is 20-70% by weight of the total filler. The amount of gutta-percha used is 13-25% by weight. Wax is
It is used as a mixture of one or more of paraffin wax, wood wax and beeswax, the proportion of which is 8-20% by weight. In addition, bismuth subcarbonate or the like is contained as an X-ray contrast agent. Since hydroxyapatite has low viscosity, it is necessary to relatively use extra gutta-percha. In addition, an application such as titanium white of about 1 to 5% by weight can be added in order to maintain aesthetics. Next, the present invention will be described in more detail by way of examples.
