塞材に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a dental filling material used for filling pits and fissures, filling electrified teeth (cavities), etc. This invention relates to a dental filling material that suppresses the growth of plaque-forming bacteria and that makes it difficult for bacteria to adhere.

部分を填塞材で密閉封鎖して口腔内環境から隔離し。(Prior art) The cause of MNA teeth is that bacteria in the oral cavity, especially Streptococcus mutans, which is a type of lactic acid bacteria, decomposes food residue adhering to the tooth surface and produces lactic acid. This is due to the elution of inorganic substances (mainly calcium phosphate) from the enamel and dentin, and the organic substances are further decomposed by the enzymes of proteolytic bacteria. In particular, the minor g fissures have a very complex morphology and are easy for bacteria to invade and adhere to, and are difficult to clean, so #A erosion is likely to occur. This pit and fissure area is hermetically sealed with a filling material and isolated from the oral environment.

The objective is to prevent #A erosion by incorporating a substance that inhibits the growth of bacteria.

見し１本発明を完成した。(Means for Solving the Problems) As a result of studying the bactericidal properties of rutile-type titanium oxide (TiO2), the present inventors found that it is effective against various bacteria that are involved in plaque formation and electrification, such as Streb 1 and C. mutans. The present invention was completed based on the finding that it has a growth inhibiting effect on oral bacteria, and that the above effect can be achieved even when mixed with dental filling materials.

る。The smaller the particle size of the rutile-type titanium oxide fine particles used in the present invention, the better the effect. In other words, areas where rutile-type titanium oxide is exposed or close to the surface of the filler after filling treatment have a significant growth inhibiting effect on bacteria, so the fine particles of rutile-type titanium oxide should be distributed as uniformly on the surface of the filler as possible. Use one with a small diameter.
