This invention discloses a tooth powder with whitening, stain removal, and anti-inflammatory effects, and its preparation method. The tooth powder is a compound of a whitening system, an antibacterial and anti-inflammatory system and a microbiome regulation system, a repair and abrasion system, and a taste-correcting and preservative system. Its core utilizes a specifically formulated biofilm complex enzyme, which can efficiently decompose dental plaque biofilm. Combined with sodium phytate and niacinamide, it achieves gentle whitening and stain removal; with epigallocatechin gallate and baicalin, it achieves targeted antibacterial and anti-inflammatory effects; with probiotic components, it regulates the oral microbiome; and with hydroxyapatite and 45S5 bioactive glass, it repairs tooth enamel. This invention employs customized embedding technology and a graded low-temperature preparation process, significantly improving the storage stability of the active ingredients. The tooth powder of this invention is gentle and non-irritating, does not damage tooth enamel, does not disrupt the oral microecological balance, and has multiple oral care effects with long-lasting and non-rebounding results, making it suitable for large-scale industrial production and long-term use by various population groups.

The objective is to provide a detection device that can detect both the amount and location of plaque attached to teeth, and accurately determine the amount of plaque within a specified range. [Solution] The detection system 1 is a detection system that detects fluorescence emitted by exciting a target object in the oral cavity of a subject, and comprises a housing 15 having a main body 10 and an insertion part 11 located at one end of the main body 10 and inserted into the oral cavity of a subject, a light guide part 23 arranged in the insertion part 11 and guiding fluorescence to the main body, a photodetection unit 24 that outputs the fluorescence intensity incident via the light guide part 23 as an intensity signal, an acceleration sensor that outputs a physical quantity related to the acceleration applied to the housing 15 as an acceleration signal, and a generation unit 32 that generates detection position information indicating the fluorescence intensity corresponding to the position of the target object based on the intensity signal and the acceleration signal.

This invention relates to the application of soybean saponin Bb in the preparation of anti-caries products, belonging to the field of biotechnology. This invention provides the application of soybean saponin Bb in the preparation of anti-caries products. In vitro experiments revealed that soybean saponin Bb inhibits the formation of cariogenic bacterial biofilms and acid production, reduces the degree of enamel demineralization, regulates the structure and metabolic function of dental plaque microbial communities, thereby improving the oral microecology. Simultaneously, soybean saponin Bb exhibits good biocompatibility and anti-caries potential in animals, suggesting that soybean saponin Bb has the potential to be developed into a novel natural anti-caries product.

The application discloses a natural eutectic solvent-based dentifrice, which takes natural eutectic solvent as an efficacy component, the hydrogen bond donor of which includes lactic acid, citric acid, maleic acid, malic acid or thymol, and the hydrogen bond acceptor includes xylitol or menthol; the natural components are combined with each other and heated to form binary or ternary eutectic solvent; then water is directly used as a solvent, or water is used as a solvent while Tween-80 or PEG-40 hydrogenated castor oil is used as an emulsifier to mix and stir to prepare the dentifrice. The preparation process is simple and low in cost; the obtained dentifrice is stable in composition, safe and friendly, has obvious dissolving capacity for common dental plaque components such as dental calculus, coffee stains, tea stains and oil stains, and can use ultrasonic waves or weak electric field to strengthen the cleaning effect. The dentifrice can also play the roles of bacteriostasis and improvement of oral odor. The process realizes all-around utilization of the eutectic solvent in oral care, and expands the application approach of the eutectic solvent in the field of health care.

The application discloses a bed patient oral cavity nursing device and relates to the technical field of oral cavity nursing.The device comprises a liquid storage tank, the inside of which is divided into two independent cavities by a partition plate, namely a liquid storage cavity for storing nursing liquid and a liquid discharge cavity for containing waste liquid; a flushing unit arranged in the liquid storage cavity for outputting the nursing liquid; a liquid discharge unit arranged in the liquid discharge cavity for sucking and discharging the waste liquid; and a biting piece fixedly connected to the outer side wall of the liquid storage tank through a support.The brush and the nozzle are integrated, the nursing liquid is directly sprayed from the nozzle embedded in the root of the brush to the tooth surface, the structure enables physical friction and hydraulic flushing to be simultaneously performed, the brush is responsible for loosening dental plaque and bacteria plaque, the pressure liquid flow is responsible for flushing away the dental plaque and the bacteria plaque and deeply cleaning the tooth gaps, and when flushing, the suction pump can immediately suck away the waste liquid through the water suction pipe, so that the safety of the nursing process is remarkably improved.

The present invention relates to the technical field of microorganisms, and specifically relates to a Lacticaseibacillus paracasei strain, a fermentation product, a live bacterial preparation, a preparation method therefor, and an application thereof. The Lacticaseibacillus paracasei strain is deposited under accession number CGMCC No. 27974. The Lacticaseibacillus paracasei strain of the present invention inhibits growth of Streptococcus mutans, reduces the formation of Streptococcus mutans-induced dental plaque biofilm, reduces mature dental plaque biofilm loads, inhibits the level of water-insoluble extracellular polysaccharides produced by Streptococcus mutans, reduces expression levels of Streptococcus mutans cariogenic genes gtfB, gtfC, gtfD, ftf, and LuxS, and can be fermented to produce fermentation products such as fermented milk and oat milk.

The present invention relates to a Lacticaseibacillus paracasei strain, a live bacterial formulation, and a preparation method therefor and the use thereof. The Lacticaseibacillus paracasei strain has the deposit number of CGMCC No.27975. Lacticaseibacillus paracasei can tolerate the oral environment, inhibit the proliferation of Streptococcus mutans, and significantly inhibit the adhesion of Streptococcus mutans on a hydroxyapatite tooth model. Lacticaseibacillus paracasei reduces the level of water-insoluble extracellular polysaccharides generated by Streptococcus mutans, effectively reduces the formation of dental plaque biofilms caused by Streptococcus mutans, reduces the content of mature dental plaque biofilms, and is less prone to experiencing biofilm formation itself. Moreover, Lacticaseibacillus paracasei significantly reduces the expression levels of cariogenic genes gtfB, gtfC, gtfD, ftf, and LuxS in Streptococcus mutans.
