Abstract
The present invention relates to contain the preparation and the tooth cleaning agent field of fluoride.The fluorine-containing anticarious tooth paste of the present invention is made up of calcic mastic and the fluorine-containing mastic contained respectively in container separately, when brushing teeth, squeeze on toothbrush, in the process of brushing teeth, mix, in the calcic mastic, provide calcium ion and part phosphate anion, and itself is as abrasivus with the calcium carbonate of indissoluble with as phosphatic calcium hydrogen phosphate of inertia and/or calcium pyrophosphate; In fluorine-containing mastic, fluorion is provided and provides the part phosphate anion with the water-soluble phosphoric acid sodium dihydrogen with water soluble fluoridized sodium, with aluminium hydroxide as abrasivus.In the process of brushing teeth, the fluorion that discharges, calcium ion and phosphate anion can remain on the certain level, and form ideal mineralising system in the oral cavity, obtain remarkable result in the control incipient dental caries.
Description
The invention belongs to preparation and the tooth cleaning agent field of containing fluoride.
Dental caries is one of the department of stomatology two big diseases, and its sickness rate is up to more than 50%, and some area, city school age population is up to 70-90%, in, old people's cervical caries is also very serious.To put prevention first, be the effective way of treatment and caries prevention in early stage control of dental caries morbidity and elimination dental caries.In the preventing decayed tooth method, using toothpaste with fluoride is one of important preventing decayed tooth means of being convenient to promote.
Past is in the anticarious tooth paste processing technology, soluble fluoride directly added in the lotion of toothpaste prepare, calcium salt as abrasivus in this soluble fluoride and the mastic meets, chemical reaction will take place inevitably, form slightly solubility calcium fluoride, prolongation along with the toothpaste resting period, the calcium fluoride that forms is many more, but, what tooth was played anticaries action is not this slightly solubility fluoride, but the fluorion that soluble fluoride dissociates out from toothpaste, it is released in the tooth external environment bacterial plaque, or directly act on the dentium nitor surface, just can play the effect of preventing and treating dental caries.Therefore, the toothpaste resting period commonly used is long more, and effectively fluorion disappears manyly more, perhaps last complete obiteration.Toothpaste with fluoride has just lost anti-caries effect like this.
Do in the toothpaste of abrasivus at the common calcium carbonate that uses, limited amount fluorion slow reaction in calcium ion in calcium carbonate and the mastic, the precipitation of formation slightly solubility calcium fluoride, in general, toothpaste dispatched from the factory the back after 10-12 month, and its effective F concentration drops to below 40% or is lower.Japanology is the result show, prepared back one month at the toothpaste of making abrasivus with simple calcium carbonate, in its mastic effectively the F ion concentration drop to 668ppm by 1350ppm, after 1 year only 1/3rd of remaining commercial weight; Make the toothpaste of abrasivus with calcium hydrogen phosphate and prepared back one month, the F ion drops to 500ppm by 1000ppm, only surplus trace after a year.Confirm also that in our experiment with the toothpaste of calcium carbonate as abrasivus, the F ion drops to 350ppm by 1000ppm in preparation after one month, drops to 60ppm after 2 months; At the toothpaste of making abrasivus with calcium hydrogen phosphate, prepare that the F ion drops to 150ppm by 1000ppm after one month, drop to trace after two months.
Institute's fluorinated volume is excessive in toothpaste, and then toxicity is higher, and side effect is arranged, but low excessively as the fluorine amount, and curative effect is poor again.Experiment showed, to keep and contain F
-The anti-dental caries ability and the remineralization effect of toothpaste must make the F in the mastic
-Be stabilized in certain level, through the incipient dental caries that toothpaste with fluoride is handled, fluorinion concentration has obvious relation in the recovery of its hardness of glaze surface value and the mastic, and is too high as fluorion, and hardness number rises unsatisfactory; Low or floride-free as crossing, then hardness number is difficult rises, thereby also is difficult to repair incipient dental caries.
In order to keep the concentration of fluorion in the toothpaste, in making toothpaste, done some improvement both at home and abroad, for example:
1) improves abrasivus composition in the toothpaste: must have the friction cleaning action as abrasivus, do not damage glaze, again not with mastic in fluorion react, therefore some toothpaste adopts slightly solubility calcium pyrophosphate or does not have the Polymeric sodium metaphosphate. of calcium, perhaps positive low inert substance such as the precipitated silica of solubility, α-Al(OH)
3And plastic grain etc. makes abrasivus, and when the former and active water soluble fluoridized sodium met, the abrasivus of calcic, phosphorus had consumption fluorine problem, only degree difference; The latter is the abrasivus of calcic, phosphorus not, though it is strong to protect fluorine, and for want of calcium and phosphate anion, its anti-dental caries limited ability.
2) use instead the low sodium monofluorophosphate of calcium ion affinity and calcium carbonate and calcium hydrogen phosphate be used: though with sodium monofluorophosphate than quite a lot of with sodium fluoride, but experimental results show that, the reduction of fluorion is still fairly obvious, and when brushing teeth with the toothpaste of like this preparation, the ionic burst size of F is few, can force rate toothpaste that isocyatic sodium fluoride is joined be low to the formation of early stage caries enamel surfaces.
3) in toothpaste with fluoride, add α-Al(OH)
3Or stabilizing agent such as non-ionic surface active agent; Pei Zhi toothpaste is after 7 months or 1 year like this, F in the toothpaste
-Retention rate also drops to 70%.
From above three kinds of approach, to add inert substance such as silicon dioxide, α-Al(OH)
3Toothpaste keeping the best aspect F ion concentration wherein stable, but weigh from the preventing decayed tooth purpose, they all lack in the fluoride in caries prevention process the environment with suitable calcium ion and phosphate anion that must provide.
From the ultimate principle of biomineralization, the demineralization of enamel-remineralization process is to carry out the reversible reaction of also reciprocal causation and mutual dependence for existence simultaneously.In oral environment, must possess an ideal mineralising system, suppress the enamel demineralization constantly, reaction is forever carried out to the single direction of remineralization, also promptly must be possessed fluorine-containing mineralising system, dental caries is repaired again based on calcium ion, phosphate anion.The chemical composition of dental enamel is a hydroxyapatite: Ca
10(PO

6(OH)
2, wherein the ratio of Ca/P is 1.67.Experiment showed, merely and make the toothpaste with fluoride of abrasivus with silicon dioxide, though contain fluorine, and it is starkly lower than the toothpaste with fluoride of calcic and phosphate anion to the remineralization usefulness of dental caries.
In order thoroughly to guarantee the usefulness of fluorine-containing anticarious tooth paste, guarantee the stability of fluorion, take at present the soluble fluoride that easy and calcic abrasivus react is packaged into two parts respectively, promptly be made into two kinds of compositionss, so that the fluorion in the mastic is not consumed by the calcium in this abrasivus, forever fluorion is remained on certain level.
WO87 02890 patent specification is divided into composition for desensitizing two parts exactly, then they are extruded respectively and mixed, thereby make fluorine component and contain the strontium component separately, but this patent is used character strontium similar to calcium without calcium, the costing an arm and a leg of used strontium chloride.
The DT2647870 patent specification is also placed apart with the compositions of the compositions of calcium ions and fluoride ion, in these two kinds of compositionss, there is one or two can contain phosphate anion, mix in use, add abrasivus when making toothpaste in addition, this abrasivus contains calcium and phosphate anion, the most handy brushite, as seen, and the end adopts calcium carbonate as abrasivus, and price is also higher.
US4080440 patent specification and US4083955 are company's applications of U.S. The Procter ﹠ Gamble Company, all be that fluorine-containing and calcareous part is placed apart, the ratio of calcium ion and phosphate anion is 0.01-100 when mixing.But used phosphate of this two patent and calcium salt are contained according to embodiment all to be ease of solubility, and chemical property is active, and what phosphate anion promptly was provided is sodium hydrogen phosphate, and what calcium ion was provided is calcium chloride.When brushing teeth, in case the two meets, chemical reaction takes place rapidly, calcium ion and phosphate anion are consumed in a large number, thereby be difficult to control for the mineralising system that is set up in the oral cavity.
Selected three examples among the embodiment of inventor from this two patent, added abrasive silicas respectively, respectively got 0.5 gram then and add the water mixing, measured calcium ion and phosphate anion respectively according to the respectively sodium hydrogen phosphate of this embodiment and the amount of calcium chloride:
1) according to the embodiment 1 of US4080440, wherein contain sodium dihydrogen phosphate 0.88(weight at anionicsite) %, contain calcium chloride 2.5(weight at cationic moiety) %, with two parts by above-mentioned add the water mixing after, recording calcium ion is 27 * 10
-2Mmol/g; Phosphate anion is 1.73 * 10
-2Mmol/g, calculating its calcium phosphorus ration is 15.6;
2) according to the embodiment 2 of US4080440, wherein contain sodium dihydrogen phosphate 1.69(weight at anionicsite) %; Contain calcium chloride 2.22(weight at cationic moiety) %, with two parts by above-mentioned add the water mixing after, recording calcium ion is 15 * 10
-2Mmol/g, phosphate ion are 5.03 * 10
-2Mmol/g, calculating its calcium phosphorus ration is 2.95;
3) according to the embodiment 2 of US4083955, wherein anionicsite contains sodium dihydrogen phosphate 3.12(weight) %, contain calcium chloride 5.00(weight at cationic moiety) %, with two parts by above-mentioned add water and mix after, recording calcium ion is 11 * 10
-2Mmol/g; Phosphate anion is 12.4 * 10
-2Mmol/g, calculating its calcium phosphorus ration is 0.89.
Find out from above result, when providing two part toothpaste of calcium ion and phosphate anion to meet respectively by active calcium chloride of chemical property and sodium hydrogen phosphate, chemical combination becomes calcium phosphate rapidly, consumption is big, the long more then consumption of brushing time is just big more, and sodium hydrogen phosphate is many more, and it is many more then to consume calcium chloride, thereby calcium phosphorus ration is just low more, and the embodiment 2 of above US4083955 is exactly this situation.
From above analysis, more than two United States Patent (USP)s, though put down in writing its calcium ion to the phosphate ion ratio range at 0.01-100, even optimal proportion is 1.67, but, from its illustrated embodiment, owing to use ease of solubility and the active raw material of chemical property, the proportion of calcium phosphorus is so big, so that be difficult to around near the fluctuation optimum 1.67, thereby the composition of product is more little near the probability of hydroxyapatite structure composition, the probability that transforms into hydroxyapatite is more little, that is to say that its mineralising effect is poor more.
The objective of the invention is to: the calcic part is being placed respectively with fluorine-containing part, during use on the blended basis, select for use the calcium salt of indissoluble to provide calcium ion and inertia phosphate that phosphate anion is provided, and the calcium phosphorus ratio that discharges after the mixing is remained in the narrow range, more be suitable for the mineralising effect of realization to create, make chemical compound that calcium ion and phosphate anion are provided abrasivus itself simultaneously as toothpaste.
The objective of the invention is to reach: in calcic (cationic moiety) mastic, provide calcium ion and part phosphate anion and, in fluorine-containing (anionicsite) mastic, fluorion is provided and provides the part phosphate anion with the water-soluble phosphoric acid disodium hydrogen with soluble fluoride as abrasivus with the inertia phosphate of the calcium carbonate of indissoluble and calcium by following measure.
