Description

The compositions of precursor gel type fluoride chewable tablet
Background technology
The fluoride preventing decayed tooth is to use the most effectively preventing decayed tooth means at present in the world.Fluorion can combine the apatite crystal of tooth and skeleton, makes it stable, and fluoride also can be attached to enamel surface, increases antiacid preventing decayed tooth ability.Fluoride can make the enamel remineralization of decalcification or hypocalcification, and is all very important to the utilization of the hardness of dentium nitor and skeleton, calcium, phosphorus.
The modes such as toothpaste agent, paste or employing fluoration foam that normally fluoride are prepared at present make tooth fully contact with fluoride with dental bed, absorb fluorion through dental bed, oral mucosa and tooth, reach the purpose of treatment and control dental caries.
At present relevant fluoride dosage form patent has the toothpaste agent; Buccal tablet and collutory etc.; Number of patent application is 95194280.8 to disclose a kind of improvement and stablize the antiseptic toothpaste compositions; Contain quintessence oil and a kind of or contain the antibiotic and dental caries dentifrice composition of improvement stable acidic of kind of fluorine compounds, be between 3.0 to 5.5 at pH value more.96115512.4 patent a kind of dental caries prevention fluoration foam is disclosed by sodium fluoride, stannous fluoride, sodium monofluorophosphate, strontium chloride; Calcium lactate, Ethyl linoleate, sodium laurylsulfate; Essence and distilled water are formulated, and damaged tooth is had mineralising repair once more.Application number is 200910042664.3 to disclose a kind of fluorine-containing anti-caries lozenge, comprises following raw materials by weight percent: sodium fluoride 0.01%, calcium lactate 5%, casein titanium phosphate 8%, stevioside 10%, Sorbitol 12%, microcrystalline Cellulose 14%, magnesium stearate 2%, essence 2%, surplus are the fluorine-containing buccal tablet of starch prescription.
These methods can make tooth and dental bed touch fluoride, have alleviated the symptom of dental caries to a certain extent.But these modes of taking medicine exist consumption to be difficult to fix, and contact site and time are difficult to control, use inconvenient shortcoming, and the effect of fluoride preventing decayed tooth is had a greatly reduced quality.
In the process that dental caries is treated, fluoride can be adsorbed on the surface skin of tooth when dental surface cleans, make tooth firmer, and taking care of one's teeth prevents decayed tooth.Root surface increases fluoride forming " softer " naturally in local fluoride administration, also helps to protect root of the tooth, makes root of the tooth lower sensitivity.The local mode fluoride is from fluorine-containing toothpaste, collutory, gel and directly be coated in the jaqan on the tooth.When the dentistry routine inspection, can coat local fluoride for the child usually, local fluoride contact treatment is to absorb one of fluorine the best way.
The another kind of method that extensively is used is " full mouth is coated with fluorine ".Full mouth is coated with the good opportunity that fluorine provides tooth to contact with fluoride.So-called complete mouthful is coated with fluorine is exactly to be coated on the fluoride of height with concentration uniformly on the surface of all teeth by the dentist, let fluoride absorbed by tooth after, the fluoride that dentist again will be unnecessary is removed totally.
Common treatment means is that fluorine-containing toothpaste is limited for the therapeutic effect of children caries with fluorine-containing toothpaste and sodium fluoride oral formulations at present, because child's tooth-brushing habit is difficult to form, the time of brushing teeth is difficult to control.The application of fluorine-containing oral formulations should be a good route of administration, but the fluorine taken all is to absorb through gastrointestinal tract, and medicine has influence on therapeutic effect in the oral cavity without reserve and absorb.The fluorine-containing glue of chewing is a kind of good selection; Fluoride, gum base and other adjuvants are pressed into the tablet or the tablet of similar chewing gum; In the oral cavity, chew glue, fluoride is discharged in the oral cavity and is absorbed and play a role by mucosa, dental bed, because partially fluorinated thing can remain in the gum base; The mode that the individual chews glue also can cause the magnitude of recruitment of fluorine different with the time, and therapeutic effect has than big-difference.
The treatment means that the specialty oral cavity is coated with fluorine has quite difficulty for child and child; At first will go to the treatment place of specialty, the treatment of dental caries is a quite very long process, and the fluoride magnitude of recruitment is difficult to control in the therapeutic process; If the ill-matched words of child, such therapeutic effect can be very poor.
Fluoride chewable tablet of the present invention can well address these problems, taking convenience, and dosage is fixed; Has the fruit taste; The gel that can produce pastille after chewing covers the surface in dental bed and tooth and oral cavity, has promoted the absorption of fluorine, has guaranteed the therapeutic effect to dental caries.
