Description
Technical field
The invention belongs to the technical field of biological material of Dental Hygienist, are related to a kind of for the antiacid preventing decayed tooth in root face that takes care of one's teeth
A kind of health care medical material, and in particular to dental root face protection materials composition.
Background technology
Tooth root face precaution measure cementum caries are carried out to the elderly, have obtained the extensive concern of domestic and foreign scholars.For
Without the cementum caries of filling treatment, the method that fluoride is mostly used using part includes the use of fluorine gel, toothpaste with fluoride etc..Fluorine
Compound is a kind of method of chemotherapy cementum caries, and the fluorine ion in fluoride can reduce dental hard tissue's solubility, is promoted
Remineralization has inhibiting effect to cariogenic bacteria.The use of toothpaste with fluoride is a kind of economic and convenient method, for the cementum caries at initial stage
Disease damage, the fluorinion concentration in safe range is higher, and anti-caries effect is better, but its preventive effect is by the shadow of patient compliance
It rings.In addition, chlorhexidine is applied not only to the drug therapy of periodontosis, moreover it is possible to effectively control cariogenic bacteria, be added in fluoride a certain amount of
Chlorhexidine, anti-caries effect is better than being used alone sodium fluoride or chlorhexidine, but should not be used for a long time.Grape seed extract contains
Procyanidine, discovery can effectively inhibit demineralization in the experiment of artificial caries remineralization in vitro, accelerate remineralization, mechanism is similar
Fluoride.Some researchs are had also been attempted using Chinese herbal medicine and food ingredients prevention cementum caries, such as tea polyphenols, Chinese gall, propolis,
But in these research also stages in the early stage, products application is not formed in clinic.
Except safeguard procedures, the Protection Product currently used for complete root face such as traditional toothpaste with fluoride can substantially be divided into fluorination
Object, resin base class and the resin base class film product for discharging fluoride.Various product has its advantage Shortcomings again：1) fluorine
Compound film, being capable of local fluoride calmness or formation fluoride.Although fluoride can adhere to certain time in dental surface,
Typically not greater than for 24 hours.Since fluoride is not high with the adhesion property of tooth and intensity is low, it is detained on tooth too short, causes to prevent
Dental caries effect reduces.2) resin base film can form mechanical barrier effect, such as various dentin bonding agents, tooth in root surface
Essential class coating material.Dentin bonding agent can be combined with cementum/dentinal permeability chemical bonding or micromechanics, in root of the tooth table
Face extended residence time.But since dentin bonding agent is relatively thin into mould, wet environment curing degree reduces, and mechanical strength is especially
It is wearability deficiency.3) the resin base film of fluoride is discharged, mechanical barrier effect can be formed simultaneously, and can discharge a certain amount of
Fluorine, such as S-PRG class coating materials.The material is by pre-reaction glass ion technology, by multifunctional glass and polymerizable organic acid
Reaction in advance, is fabricated to filler (reacting glass ion in advance in surface), this product is compared with fluorine class coating material, by force by product
Degree increases, and it is strong that fluorine effect is released in performance.But it is still necessary to further study for abrasion resistance properties.
In general, diseased Root Surfaces Protection Product type is few, and effect needs further to be verified.China is current, does not have in the market
The product of same type, it is unique the effect of similar products be Colgate-Palmolive how happy fluorine, still, there are following several for the how happy fluorine of Colgate-Palmolive
A problem：1) diet in the long period after operation is required to prevent diet, brushing teeth leads to its abrasion；2) color is partially yellow,
It influences beautiful；3) how happy fluorine can not form the protective layer of some strength in the zone of action of tooth, and intensity is relatively low, it is impossible to long-acting
Outer protection is provided.The validity and chronicity for improving diseased Root Surfaces Protection Product are how integrated, extends Protection Product action time
With reduction Protection Product frequency of use, it is a problem to be solved.
