Abstract

The invention relates to a bioactive glass ceramic material. The bioactive glass ceramic material belongs to a Na2O-CaO-SrO-SiO2-P2O5-F system, and comprises the following components in percentage by weight: 12-45% of SiO2, 10-35% of P2O5, 25-48% of CaO, 5-15% of Na2O, 3.5-4.9% of SrO, and 1.5-2.1% of F; and the main compositions of a crystalline phase in the bioactive glass ceramic material are hydroxyapatite, tricalcium phosphate and calcium sodium phosphate. The invention also provides a preparation method of the bioactive glass ceramic material, which comprises a powder calcinating method, a high-temperature melting method, and a coprecipitation synthesis method or a sol-gel method. The invention further provides the application of the bioactive glass ceramic material in oral care products. The bioactive glass ceramic material and a conventional oral care product carrier or a transfer agent are prepared into oral care products such as toothpastes, mouthwash, tooth powder, tooth gel, chewing gum, and the like, and the bioactive glass ceramic material can achieve an effect of effectively preventing dentine hypersensitivity and promoting the surface remineralization of teeth in the process of teeth cleaning.

Description

technical field

[0001] The invention belongs to the field of bioactive glass ceramics, and in particular relates to a bioactive glass ceramic material whose crystalline phase is mainly composed of hydroxyapatite, tricalcium phosphate and sodium calcium phosphate and its preparation method and its application in toothpaste, tooth powder, etc. Sensitive oral care applications. Background technique

[0002] Dentin hypersensitivity (DH) is a common and frequently-occurring disease in the oral cavity. According to hydrodynamics, reducing the diameter of dentinal tubules and closing the openings of dentinal tubules to reduce and avoid fluid flow in dentin is the fundamental way to treat dentin sensitivity. The current treatment concept of anti-dentin hypersensitivity is gradually changing to early diagnosis and minimally invasive treatment, and the mineralization restoration treatment of dentinal tubules is well in line with this development trend. In long-term practice, it has ...
