Description

Oral cavity cleaning instrument and tooth cleaning paste thereof
The invention relates to an oral cavity cleaning instrument, belongs to the technical field of manufacturing of oral cavity health care instruments, and relates to a device for cleaning and cleaning oral cavity, removing tartar and preventing dental plaque, dental calculus and decayed teeth and a toothpaste matched with the device.
Dental caries is one of the major common diseases endangering human health, and is the leading cause of oral diseases. According to incomplete statistics, more than 60% of the population of our country suffers from caries with different degrees, and the harm to children is particularly serious. Dental caries is mainly caused by poor oral cleanliness, so that some cariogenic bacteria such as streptococcus acidogenesis, lactobacillus, actinomyces and the like are attached to the surface of a tooth body and multiply to form bacterial plaques on the surface of the tooth, and the bacteria decompose carbohydrate food residues to generate acid, decalcify and disintegrate tooth enamel to cause dental caries lesions, and gradually diffuse to the tooth body layer to form a caries cavity, so that the bacteria invade a root canal to cause periapical disease, dental pulp disease and even jaw disease. Serious caries can cause systemic diseases such as heart disease and the like, and the harm is great. Because the dental caries ring can not be recovered by itself, once the dental caries is caused, the dental caries ring is accompanied with lifetime, teeth have to be pulled out in serious cases, and the physical and psychological health of a patient is influenced, so that the maintenance of the cleanness of the oral cavity and the prevention of the dental caries are very important. Prevention of dental caries generally starts from two aspects: 1. cleaning oral cavity, removing food (especially carbohydrate-rich food) residue on tooth surface, removing nutrient source for bacteria, and preventing damage of enamel caused by polysaccharide and acid substances generated by bacteria decomposing residue. 2. The cariogenic bacteria attached to the surface of teeth, especially streptococcus mutans, are killed, and the cariogenic bacteria have the greatest harm to the teeth.
The existing caries prevention mainly adopts various toothpastes (including medicinal toothpaste and tooth powder) and toothbrushes to brush teeth so as to clean the surfaces of the teeth; or gargling with a cleanser; or drinking fluorine-containing water. These methods are primarily directed to cleaning the oral cavity, removing food debris from the surface of the teeth or forming acid-resistant fluorapatite on the surface of the teeth. However, most people have difficulty in brushing teeth immediately after meals, and the brushing method is not standard, so that the cleaning of the tooth surfaces is not thorough. Especially, because the teeth have complicated structure and are arranged in zigzag, the pits and grooves of the chewing surface and the adjacent surfaces between the teeth are the places for storing dirt and dirt, the caries usually starts from the first place, and the aim of preventing caries can not be achieved.
The invention aims to overcome the defects of the prior art and provide an oral cavity cleaning instrument which can decompose residual organic matters and effectively kill cariogenic bacteria by utilizing the photocatalytic action of semiconductor ceramic to generate photocatalytic oxidation reaction on the surface of teeth and clean toothpaste matched with the oral cavity cleaning instrument.
The object of the invention can be achieved by the following measures: after light emitted by the ultraviolet light source passes through the optical filter, the near ultraviolet light with the wavelength of 300-400nm is focused by the condensing lens and then enters the optical fiber to reach the optical probe at the tail end of the optical fiber to irradiate the surface of the tooth coated with the clean toothpaste; the tooth cleaning paste coated on the tooth surface is preparedby mixing 20-30% of photocatalytic semiconductor ceramic powder, 40-50% of additive for preparing paste and the balance of water at normal temperature.
The object of the invention is also achieved by the following measures: the light source, the optical filter and the condenser lens are arranged in a sealed light source box, and the optical probe connected by the optical fiber is provided with a handle and a light shield.
The object of the invention is also achieved by the following measures: the tooth cleaning paste coated on the tooth surface is prepared by mixing 20-30% of photocatalytic semiconductor ceramic powder, 40-50% of additive for preparing paste and the balance of water at normal temperature.
The object of the invention is also achieved by the following measures: the additive for preparing the tooth cleaning paste comprises semiconductor ceramic powder: 20-30%, calcification agent: 9-12%, surfactant: 22-26%, stabilizer: 5-7%, foaming agent: 0.9-1.3%, preservative: 0.1-0.3%, sweetener: 0.2-0.3%, perfume: 0.8 to 1.1 percent.
The object of the invention is also achieved by the following measures: the photocatalytic semiconductor ceramic powder is anatase type titanium dioxide powder; or zinc oxide powder; or rutile titanium dioxide powder; or gamma-alumina powder.
The object of the invention is also achieved by the following measures: 0.05-1.0ug/cm is adsorbed on the surface of the semiconductor ceramic powder2The metals of Au, Ag, Pd, Pt, Rh, Cu, Fe, Co, Ni and the like have the promotion effect on the photocatalytic reaction.
The attached drawing is a principle drawing of the invention.
The invention will be further illustrated with reference to the accompanying drawings and examples:
as shown in the figure: after light emitted by the ultraviolet lamp (1) passes through the ZWB2 and the ultraviolet filter (2), the ultraviolet light with the wavelength of 300-. The ultraviolet light source can be a low-pressure mercury lamp, an ozone-free ultraviolet sterilizing lamp, a black light lamp or a fluorescent lamp containing more ultraviolet rays. The ultraviolet lamp (1), the optical filter (2) and the condenser lens (3) are all arranged in a light source box and are externally connected with an optical fiber (4).
When in use, a small amount of tooth cleaning paste is dipped by a toothbrush and coated on each surface of teeth to form a thin layer. The light probe (5) is placed in the oral cavity, the teeth are aligned, the light source is turned on, and the surfaces, gaps and adjacent surfaces of the teeth are irradiated in sequence for 3-5 minutes each time. The following photocatalytic reactions occur on the tooth surface upon irradiation:
the generated hydroxyl radical (. OH) is an extremely strong oxidant, superoxide ion (O)2 -) Are extremely strong reducing agents and their reactivity is very high. In particular, the (. OH) group can oxidize and decompose any organic matter, kill various bacteria and fungi, and even decompose secretion and dead bodies thereof. Thereby cleaning oral cavity, removing organic matter attached to tooth surface, removing bacterial nutrient source and killing bacteria, and preventing dental caries.
After irradiation, the light source is turned off, the light probe is collected, and the mouth is rinsed with clear water and treated once before sleep every day or every other day. The toothpaste also has effects in preventing and treating periodontitis, gingivitis, and dental abscess, preventing and removing dental calculus, and eliminating halitosis.
