The invention relates to the technical field of biomedical materials, in particular to a COF heterojunction nanosphere with biomimetic mineralization and antibacterial functions and a preparation method and application thereof. The preparation method comprises the following steps: mixing a magnolol solution, a 1, 3, 5-tris (4-aminophenyl) benzene solution, a polyvinylpyrrolidone solution, a 2, 5-dimethoxybenzene-1, 4-dicarboxaldehyde solution and acetic acid, so as to obtain COFDMTP-coated Honokiol nanospheres; the preparation method comprises the following steps: mixing 4, 4 '-((2, 5-diformyl-1, 4-phenylene) bis (oxy)) dibutyric acid, COFDMTP (at) Honokiol nanospheres, acetonitrile and an acetic acid solution, and reacting to obtain the COFFPBA (at) Honokiol heterojunction nanospheres. The heterojunction nanosphere provided by the invention not only can promote the mineralization of acid-etched enamel, but also can effectively inhibit the growth of oral bacteria and reduce the occurrence of decayed teeth.

The invention discloses an embedded tooth traction device and method, and belongs to the technical field of orthodontic tools. The device comprises a bonding ring, a combined ring and a stress application unit, the bonding ring, the combined ring and the stress application unit are integrally made of orthodontic ligature wires, the bonding ring can be tightly attached according to the radian of the surface of an embedded tooth, the combined ring comprises a plurality of continuous ligature rings and can be adjusted in direction according to a preset track, and the stress application unit adopts TP elastic cotton threads or NITI wires to provide traction force. The traction method comprises the steps of surgical exposure of embedded teeth, sufficient hemostasis, acid etching and bonding, direction adjustment, surgical suture, closed traction, stress application, revival adjustment and the like. The problems that an existing traction accessory is low in sealing degree, prone to falling off, uncontrollable in traction direction, difficult in closed traction suturing and capable of damaging periodontium are solved, the traction accessory has the advantages of being firm in bonding, accurate in traction, minimally invasive, friendly, low in cost and convenient and fast to operate, the traction success rate of the embedded tooth can be effectively increased, and pain of a patient is relieved.

An oral care composition is disclosed, comprising: a dental ligand mixture comprising a monocarboxylic acid, a dicarboxylic acid, and / or a tetracarboxylic acid; and a stannous ion source and a fluoride ion source, such as stannous fluoride. The oral care composition exhibits the ability to prevent and / or treat tooth erosion and / or dental caries.

The application discloses anhydrous toothpaste and a preparation method thereof. The anhydrous toothpaste comprises a humectant, a thickening agent, an abrasive and an efficacy component; the humectant is composed of at least one of PEG 400 and propylene glycol and glycerol, and the amount of the glycerol is not more than 40% of the total weight of the anhydrous toothpaste; the thickening agent comprises microcrystalline cellulose; the abrasive is composed of at least one of calcium hydrogen phosphate dihydrate and calcium pyrophosphate and calcium hydrogen phosphate and hydrated silica, and the calcium hydrogen phosphate is the main abrasive; and the efficacy component comprises sodium monofluorophosphate and sodium phytate. The anhydrous toothpaste can improve the burning and irritating taste of the anhydrous toothpaste; the calcium hydrogen phosphate is used as the main abrasive, the sodium monofluorophosphate is used as a repairing and remineralizing component, the two components are compatible, the soluble fluorine concentration can be improved, and the tooth remineralization and acid erosion resistance can be ensured; and the microcrystalline cellulose thickening does not need to be neutralized and is resistant to high-speed shearing, so that the system damage caused by incompatible raw materials during the shelf life is avoided, and the stability is improved.
