Description
Munn- og tannpleiemidler for caries profylaksis. Oral and dental care products for caries prophylaxis.
Nærværende oppfinnelse vedrorer stabile munn- og tannpleiemidler som inneholder et vannopploselig fluorid for forebyggelse av caries. The present invention relates to stable oral and dental care agents containing a water-soluble fluoride for the prevention of caries.
Med uttrykket "munn- og tannpleiemidler", slik som det anvendes her forstås et produkt som ved sin vanlige bruk ikke er bestemt til å svelges, men beholdes i munnhulen i tilstrekkelig tid til å komme i kontakt med alle dentale overflater. Slike produkter omfatter f.eks. tannpleimidler, munnvann, tyggegummi og dentale forebyggende pastaer og opplosninger for anvendelse på tannlegekontoret. The term "oral and dental care products", as used here, means a product which, in its normal use, is not intended to be swallowed, but is retained in the oral cavity for a sufficient time to come into contact with all dental surfaces. Such products include e.g. dentifrices, mouthwash, chewing gum and dental preventive pastes and solutions for use in the dental office.
Det er kjent at visse metallioner kan ha en vesentlig effektIt is known that certain metal ions can have a significant effect
på den anticariogehe effektivitet for munn- og tannpleiemidler. F.eks. en rekke videnskapelig litteratur viser at bruken av on the anticariogehe effectiveness of oral and dental care products. E.g. a number of scientific literature shows that the use of

Et av problemene som har utviklet seg ved formuleringen avOne of the problems that has developed in the formulation of
munn- og tannpleiemidler som inneholder tinn(II)forbindelser, særlig vandige preparater, er tilbbyeligheten til dette metall å oksydere til sitt hoyere valensstadium, hydrolysere til stannohydroksyd og/eller reagere med andre bestanddeler i preparatet og danne meget stabile komplekser eller meget uopp-løselige forbindelser. Opptreden av en eller flere av forannevnte reaksjoner kan gjore tinnet ikke-reaktivt med dental-emalje. Stannotinn i sin ikke-reaksjonsdyktige tilstand be-tegnes her som "utilgjengelig". oral and dental care products containing tin(II) compounds, especially aqueous preparations, the tendency of this metal to oxidize to its higher valence stage, hydrolyze to stannous hydroxide and/or react with other components in the preparation and form very stable complexes or very insoluble connections. The occurrence of one or more of the aforementioned reactions can make the tin non-reactive with dental enamel. Stannotin in its non-reactive state is referred to here as "unavailable".
Forskjellige forsok har vært gjort for å holde stannotinn i dental-emalje-reaksjonsdyktig form. F.eks. beskriver U.S. Various attempts have been made to keep stantinoin in a dental-enamel-reactive form. E.g. describes the U.S.
patent nr. 2.946.725 bruken av et lite opploslig stannosalt slik som stanno-pyrofosfat som et "reservoir" for stannoion i forbindelse med et vannopploselig stannosalt, slik som stanno-fluorid. Etterhvert som stannoionet som avledes fra det opplbselige salt reagerer med dental-emalje eller blir utilgjengelig ved hydrolyse etc, opploser det sparsomme oppløselige stannosalt seg langsomt for å ersatte det forbrukte stannoion. Imidler- patent no. 2,946,725 the use of a slightly soluble stannous salt such as stannous pyrophosphate as a "reservoir" for stannous ion in conjunction with a water soluble stannous salt such as stannous fluoride. As the stannous ion derived from the soluble salt reacts with dental enamel or becomes unavailable by hydrolysis etc., the scarce soluble stannous salt slowly dissolves to replace the consumed stannous ion. However-
tid hydrolyserer pyrofosfatanionet til ortofosfat ved aldring med det resultat at reservoirevnen for stannopyrofosfat grad-vis avtar. time, the pyrophosphate anion hydrolyzes to orthophosphate during aging, with the result that the reservoir capacity for stannous pyrophosphate gradually decreases.
U.S. patent nr. 3.1o5.798 beskriver et fremskritt overfor forannevnte amerikanske patent som omfatter opprettholdelsen av dental-emalje-reaksjonsdyktig stannotinn ved kompleksdan-nelse av SN(II) ion med en lavere syre til et vannopploselig stannoaldonat. Et lignende forsok på å opprettholde stannotinn i en stabil og tilgjengelig form foreslår bruken av stannokomplekser av hydroksyetylnitrilatdieddiksyre, metahydroksy- benzosyre, 1,2,3-propantrikarboksylsyre, itakonsyre eller eple-syre for dette formål. Disse komplekser karakteriseres ved deres opploselighet i vandig opplosning og styrken av disse komplekser er slik at stannotinn er beskyttet fra inaktiverende påvirkninger, dog ikke så sterk at reaksjon med dental-emal- U.S. patent no. 3,105,798 describes an advance over the aforementioned US patent which includes the maintenance of dental-enamel-reactive stannous tin by complexing the SN(II) ion with a lower acid to a water-soluble stannous aldonate. A similar attempt to maintain stannotin in a stable and accessible form suggests the use of stannous complexes of hydroxyethylnitritediacetic acid, metahydroxybenzoic acid, 1,2,3-propanetricarboxylic acid, itaconic acid or malic acid for this purpose. These complexes are characterized by their solubility in aqueous solution and the strength of these complexes is such that stannotine is protected from inactivating influences, although not so strong that reaction with dental enamel
je forhindres. Det forannevnte forslag og også forslaget i U.S. patent nr. 3.1o5.798 for å opprettholde stannotinn betegner et kompromiss mellom stabilitet og reaksjonsvillighet, med det resultat at det tinn som leveres av det nevnte kompleks ikke er så tilgjengelig for reaksjon med dental-emalje som tilfel-let vil være med et mindre stabilt kompleks. you are prevented. The aforementioned proposal and also the proposal in the U.S. patent no. 3,105,798 to maintain stannotine tin represents a compromise between stability and reactivity, with the result that the tin provided by said complex is not as available for reaction with dental enamel as would be the case with a smaller stable complex.
Det er nå funnet en annen og mere effektiv måte for å opprettholde reaksjonsvillig stannotinn som omfatter fremskaffelsen av visse lite opploselige organiske stannosalter som langsomt loser seg opp og gir svake stannokomplekser. Disse kompleksene er mere reaksjonsvillige med dental-emalje enn tidligere kjente opploslige komplekser, men anionene er mer stabile overfor hydrolyse enn pyrofosfåtene etter amerikansk patent nr. 2.946.725, hvilket resulterer i storre stabilitet ved aldring. Således kan fordelen ved begge disse eldre forslag for opprettholdelsen av stannotinn realiseres ved nærværende oppfinnelse. Another and more efficient way of maintaining reactive stannous tin has now been found which involves the provision of certain poorly soluble organic stannous salts which slowly dissolve and give weak stannous complexes. These complexes are more reactive with dental enamel than previously known soluble complexes, but the anions are more stable to hydrolysis than the pyrophosphates of US Patent No. 2,946,725, resulting in greater stability upon aging. Thus, the advantage of both of these older proposals for the maintenance of stantinoin can be realized by the present invention.
I tillegg til fordelene som stannosaltene etter nærværende oppfinnelse gir fra standpunktet å opprettholde stannotinn i en stabil og reaksjonsvillig form, tjener det også til å forsinke utviklingen av tannsten ved å gripe inn i kalsiumhydroksyapa-tittkrystallveksten. Munn- og tannpleiemidler som inneholder slike salter gir derfor både forbedret virkning med hensyn til anticaries og tannstensdannelse. In addition to the advantages which the stannous salts of the present invention provide from the standpoint of maintaining stantinoin in a stable and reactive form, it also serves to delay the development of calculus by interfering with calcium hydroxyapatite crystal growth. Oral and dental care products containing such salts therefore provide both an improved effect with regard to anticaries and tartar formation.
Nærværende oppfinnelse vedrorer således et munn- og tannpleiemiddel som inneholder et vannopploselig fluorid, fortrinnsvis stannofluorid, i en mengde tilstrekkelig til å gi fra 100 til 4000 ppm. av fluoridion og med en pH fra 2,5 til 7,0, og mid-let karakteriseres ved at det inneholder fra 0,05 til 5,0 vekts% av et distannosalt av en gem-difosfonsyre med formlen: hvor R1betegner hydrogen, halogen, en hydroksyl-, metoksy-, benzyl eller alkylgruppe med fra 1-12 karbonatomer, og R2betegner hydrogen, halogen, en hydroksyl-, metoksy-, acetyl-, fenyl-, benzyl- eller alkylgruppe med fra 1-12 karbonatomer. The present invention thus relates to an oral and dental care product which contains a water-soluble fluoride, preferably stannous fluoride, in an amount sufficient to provide from 100 to 4000 ppm. of fluoride ion and with a pH from 2.5 to 7.0, and the agent is characterized in that it contains from 0.05 to 5.0% by weight of a distanosalt of a gem-diphosphonic acid with the formula: where R1 denotes hydrogen, halogen , a hydroxyl, methoxy, benzyl or alkyl group with from 1-12 carbon atoms, and R2 denotes hydrogen, halogen, a hydroxyl, methoxy, acetyl, phenyl, benzyl or alkyl group with from 1-12 carbon atoms.
Gem-difosfonsyrer fra hvilke stannosaltene avledes kan f.eks. fremstilles ved alkylering ved de sentrale karbonatomer i te-traalkyl-metan-difosfonater med en alkylhalid i overensstem-melse med fremgangsmåten som er beskrevet av G.M. Kosolopoff i J.Amer.Chem.Soc., 75, 1500 (1953). Foretrukne metoder for fremstilling av alternative gem-difosfonsyrer er beskrevet i de folgende patenter: Gem-diphosphonic acids from which the stannous salts are derived can e.g. is prepared by alkylation at the central carbon atoms of tetraalkyl methane diphosphonates with an alkyl halide in accordance with the method described by G.M.

Mengden av fluoridsalt som brukes i preparatene efter nærværende oppfinnelse må være tilstrekkelig til å gi minst ca. 25 The amount of fluoride salt used in the preparations according to the present invention must be sufficient to give at least approx. 25
deler fluoridioner pr. million deler totalt preparat. Ekstremt store mengder fluoridioner synes ikke å oke forbindelsens onskede egenskaper og kan forårsake at den har giftige egenskaper. Folgelig inneholder preparatene efter nærværende oppfinnelse ikke mer en 4000 deler fluorion pr. million deler totalt preparat, og i tilfelle av tannpleiepreparater ikke mer enn ca. 3000 deler pr. million. parts fluoride ions per million parts total preparation. Extremely large amounts of fluoride ions do not appear to increase the desired properties of the compound and may cause it to have toxic properties. Consequently, the preparations according to the present invention contain no more than 4,000 parts of fluorine per million parts of total preparation, and in the case of dental care preparations no more than approx. 3000 parts per million.
Distanno gem-difosfonat kan utgjore fra 0.05 til 5.0 vektsprosent av preparatene ifolge oppfinnelsen. Mindre enn 0.05% er ikke tilstrekkelig til å gi effektive nivåer for reaksjonsdyktig stannotinn under den vanlige levetid for produktet. Mer enn 5.0% av denne komponent vil gi en astringerende smak og forårsake smakstilsetningsproblemer. Fortrinnsvis anvendes distanno gem-difosfonatene i konsentrasjon innen området 0.1 til 1.0 vektsprosent. Distanno gem diphosphonate can form from 0.05 to 5.0% by weight of the preparations according to the invention. Less than 0.05% is not sufficient to provide effective levels of reactive stannotine during the normal life of the product. More than 5.0% of this component will give an astringent taste and cause flavoring problems. Preferably, the distanno gem diphosphonates are used in a concentration in the range of 0.1 to 1.0% by weight.
Fortrinnsvis anvendes stannofluorid som en ytterligere kildePreferably stannous fluoride is used as an additional source
for stannotinn og i en mengde tilstrekkelig til å gi minst 300 ppm. stannotinn og ikke mer enn 4000 ppm fluoridion. Imidlertid kan alt stannotinnet som inneholdes i disse preparatene, stamme f-a stanno gem-difosfonatene. Under enhver om-stendighet kan det totale stannotinninnhold være fra 15 til 10.000 ppm og det foretrukne området er fra 50 til 8000 ppm. for stantinoin and in an amount sufficient to give at least 300 ppm. stannotine and not more than 4000 ppm fluoride ion. However, all the stannous tin contained in these preparations may originate from the stannous gem diphosphonates. In any case, the total stantin content can be from 15 to 10,000 ppm and the preferred range is from 50 to 8,000 ppm.
Det vil være klart for fagmannen på området at munn- og tannpleiemidler ifolge nærværende oppfinnelse også kan fremstilles ved å tilsette en gem-difosfonsyre som her definert til et vannopploselig stannosalt slik som stannofluorid eller stannoklorid for å danne et tilsvarende distanno gem-difosfonat in situ. It will be clear to the person skilled in the art that oral and dental care agents according to the present invention can also be prepared by adding a gem-diphosphonic acid as defined here to a water-soluble stannous salt such as stannous fluoride or stannous chloride to form a corresponding distanno gem-diphosphonate in situ.
pH for preparatene ifolge nærværende oppfinnelse ligger mellom 2.5 til 7, og det foretrukne området er fra 4 til 6.5. Over pH ca. 7 kan tap av tilgjengelig stannoioner for reaksjon med emalje være for hurtig og visse smakstilsettende stoffer, The pH of the preparations according to the present invention is between 2.5 to 7, and the preferred range is from 4 to 6.5. Above pH approx. 7 loss of available stannous ions for reaction with enamel may be too rapid and certain flavoring substances,
særlig estere, odelegges hurtig. En for lav pH, under 2.5,especially esters, break down quickly. A too low pH, below 2.5,
gir en astringerende smak som ikke tiltaler de fleste. Den akselererer også hydrolysen av visse skummende midler og gir derved en ubehagelig"fettsyresmak" og reduserer mengden av skum som oppnås ved bruk. Dessuten, pH-verdier under 2.5 har tendens til å forårsake korrosjon av metalltuber i hvilke preparatet kan være lagret, og ha tendens til å hydrolysere andre komponenter slik som kondenserte fosfater hvis disse brukes som slipemidler. Slik hydrolyse kan nedsette tilgjengeligheten av stannoioner ved gives an astringent taste that does not appeal to most people. It also accelerates the hydrolysis of certain foaming agents thereby imparting an unpleasant "fatty acid taste" and reducing the amount of foam obtained in use. Also, pH values below 2.5 tend to cause corrosion of metal tubes in which the preparation may be stored, and tend to hydrolyze other components such as condensed phosphates if these are used as abrasives. Such hydrolysis can reduce the availability of stannous ions by
å gi anioner med hvilke de kan danne meget stabile komplekser eller med hvilke de kan felles ut som meget,uopploselige forbindelser. to give anions with which they can form very stable complexes or with which they can precipitate as very, insoluble compounds.
Foruten de vanlige komponentene som er beskrevet herBesides the usual components described here
kan preparatene efter nærværende oppfinnelse inneholde de vanlige bestanddeler i tannpleiemidler, munnvann etc. F.eks. inne- can the preparations according to the present invention contain the usual ingredients in dental care products, mouthwash etc. E.g. in-
holder tannpasta vanligvis et slipe-middel, skummende middel, bindemiddel, fukte-middel, smaksettende og sotende materiale. toothpaste usually contains an abrasive, foaming agent, binder, wetting agent, flavoring and sooting material.
Slipemidlene skulle fortrinnsvis være relativt uopploselige og relativt stabile ved de pH-områder som er angitt. De skal ikke være for slipende, slik at tannoverflåtene ikke ripes eller uheldig påvirker dentinet, men de skal ha akkurat tilstrekkelig slipende evne til å rense tennene. Ved utforelsen av nærværende oppfinnelse kan ethvert slipemiddel brukes som har disse egenskaper og er tilstrekkelig forenbart med stannoion og fluoridion. The abrasives should preferably be relatively insoluble and relatively stable at the pH ranges indicated. They should not be too abrasive, so that the tooth surfaces are not scratched or adversely affect the dentin, but they should have just enough abrasive ability to clean the teeth. In carrying out the present invention, any abrasive can be used which has these properties and is sufficiently compatible with stannous ion and fluoride ion.
Foretrukne slipemidler for anvendelse i de fluoridholdige tannpleiemidler i nærværende oppfinnelse omfatter de uopploselige kondenserte fosfater og de vann-ugjennomtrengelige kryssbundne, termoherdende harpikser. Eksempler på slike uopploselige kondenserte fosfater omfatter kalsium-pyrofosfat, uopploselig hoyt polymerisert kalsium-polyfosfat, noen ganger kalt kalsium-polymetafosfat, og uopploselig hoyt polymerisert natrium-polyfosfat, noen ganger kalt uopploselig natrium-metafosfat. Eksempler på brukbare harpiksslipemidler er de partikkelformede kondensasjonsproduktene av formaldehyd med melamin og/eller urea, og andre mer fullstendig beskrevet i U.S. patent 3.070.510. Blandinger av slipemidler kan også brukes. Preferred abrasives for use in the fluoride dentifrices of the present invention include the insoluble condensed phosphates and the water impermeable cross-linked thermosetting resins. Examples of such insoluble condensed phosphates include calcium pyrophosphate, insoluble highly polymerized calcium polyphosphate, sometimes called calcium polymetaphosphate, and insoluble highly polymerized sodium polyphosphate, sometimes called insoluble sodium metaphosphate. Examples of useful resin abrasives are the particulate condensation products of formaldehyde with melamine and/or urea, and others more fully described in U.S. Pat. patent 3,070,510. Mixtures of abrasives can also be used.
Den totale mengde slipende midler i tannpleien ifolge nærværende oppfinnelse kan variere fra 0.5 til 95 vektsprosent av tannpleiemidlene. Fortrinnsvis inneholder tannpasta fra 20 til 60 vektsprosent, og tannpulveret inneholder fra 60 til 95 vektsprosent . The total amount of abrasive agents in the dental care according to the present invention can vary from 0.5 to 95 percent by weight of the dental care agents. Toothpaste preferably contains from 20 to 60 percent by weight, and the tooth powder contains from 60 to 95 percent by weight.
Tannpleiemiddel inneholder vanligvis skummende middel, skjont disse er ikke kritiske ved utforelsen av nærværende oppfinnelse. Ethvert av de vanlig skummende midler kan brukes, hvis de Dentifrices usually contain foaming agents, although these are not critical in the implementation of the present invention. Any of the usual foaming agents can be used, if they
er stabile i rimelig grad og danner skum innen pH-området, for preparatene efter oppfinnelsen. Eksempler på egnede skummende midler omfatter vannopploselige alkylsulfater som har alkylgrup-per med fra ca. 8 til 18 karbonatomer, slik som natriumkokosnott-monoglyserid-sulfonat, salter av fettsyreamider av taurider, slik som natrium-N-metyl-N-palmitoyl-taurid, salter av fettsyreestere av isetionsyre og i det vesentlige mettede alifatiske acylamider av mettede alifatiske monoaminokarboksylsyrer med fra 2-6 karbonatomer og i hvilke acylradikalet inneholder 12 til 16 karbonatomer, are stable to a reasonable extent and form foam within the pH range, for the preparations according to the invention. Examples of suitable foaming agents include water-soluble alkyl sulphates which have alkyl groups with from approx. 8 to 18 carbon atoms, such as sodium coconut monoglyceride sulfonate, salts of fatty acid amides of taurides, such as sodium N-methyl-N-palmitoyl tauride, salts of fatty acid esters of isethionic acid and substantially saturated aliphatic acylamides of saturated aliphatic monoaminocarboxylic acids with from 2-6 carbon atoms and in which the acyl radical contains 12 to 16 carbon atoms,
slik som natrium-N-lauroyl-sarkosid. Blandinger av to eller flere skummende midler kan også brukes. such as sodium N-lauroyl sarcoside. Mixtures of two or more foaming agents can also be used.
Skummende midler kan anvendes i preparatene i nærværende oppfinnelse i en mengde på fra 0.5 til 5.0 vektsprosent av det totale preparat. Foaming agents can be used in the preparations of the present invention in an amount of from 0.5 to 5.0% by weight of the total preparation.
Ved fremstilling av tannpastaer er det nodvendig å tilsette noe fortykkende materiale. Foretrukne fortykningsmidler er vannopploselige salter av celluloseetere slik som natriumkarboksymetyl-hydroksyetylcellulose. Naturlige gummier, slik som karayagummi, arabisk gummi og tragakantgummi kan også brukes som fortykkende middel, men kan ha tendens til å forårsake uonskelig lukt eller smak i noen formuleringer. Kolloidalt magnesiumaluminiumsilikat eller findelt silisiumoksyd kan brukes som en del av det fortykkende middel for forbedring av tekstur.Fortykkende midler kan brukes i en mengde på ca. 0.5 til 5.0 vektsprosent av tannpasta for å gi denne en tilfredsstillende form. When making toothpastes, it is necessary to add some thickening material. Preferred thickeners are water-soluble salts of cellulose ethers such as sodium carboxymethyl-hydroxyethyl cellulose. Natural gums, such as gum karaya, gum arabic and gum tragacanth can also be used as a thickening agent, but may tend to cause an undesirable odor or taste in some formulations. Colloidal magnesium aluminum silicate or finely divided silicon oxide can be used as part of the thickening agent to improve texture. Thickening agents can be used in an amount of approx. 0.5 to 5.0 percent by weight of toothpaste to give it a satisfactory shape.
Egnede fuktemidler omfatter glyserin, sorbitol og andre flerverdige alkoholer. Fuktemidlene kan utgjore opptil ca. Suitable wetting agents include glycerin, sorbitol and other polyhydric alcohols. The humectants can make up to approx.
35% av tannpastasammensetningen.35% of the toothpaste composition.
Munn- og tannpleiemidler kan videre inneholde små mengder av smakstilsettende midler, slik som vintergrontolje, pepper-mynteolje, sassafrasolje og anisolje. Små mengder av sotende midler, slik som sakkarin, dekstrose, levulose og natriumcykla-mat tilsettes også hensiktsmessig til slike preparater. Oral and dental care products may also contain small amounts of flavoring agents, such as wintergreen oil, peppermint oil, sassafras oil and anise oil. Small amounts of sooting agents, such as saccharin, dextrose, levulose and sodium cyclamate are also suitably added to such preparations.
Flere utforelsesformer for tannpasta efter nærværende oppfinnelse blir fremstilt ved anvendelse av vanlige blandemetoder og undersdkelser på stabilitet og for tilgjengelighet for reaksjon med dentalemalje. Several embodiments of toothpaste according to the present invention are prepared using common mixing methods and investigations on stability and availability for reaction with dental enamel.
Stabiliteten for tannpasta ved aldring med hensyn til å tilfore emalje reaksjonsvillig stannotinn ble målt ved en aksellerert aldringsprove som utfores på folgende måte: En prove inkuberes ved en temperatur på 50°C og efter angitt tidsintervall bestemmes opploselig stannotinn-konsentrasjon ved å blande 1 del tannpasta med 3 deler destillert vann i 10 minutter. De faste stoffer fjernes derefter ved sentrifugering i 30 minutter ved 12.000 omdreininger pr. min. og stannotinn-konsentrasjonen i en alikvot del av den ovenstående væske bestemmes jodometrisk. En annen del av proveeksemplet justeres derefter og holdes ved pH 6.2, blandes med vann (1 del pasta til 3 deler vann) i 1 time, sentrifugeres som foran nevnt og en annen analyse på stannotinn foretas. Da okning av pH til dette nivå resulterer i oppløsningen av alt av den uopploste andel av distannosaltet, gir den annen verdi et mål for"reservoir"-virkningen av disse salter. Resultatene gjengis i det folgende som deler pr. million opploselig stannotinn. The stability of toothpaste during aging with regard to adding reactive stannotin to enamel was measured by an accelerated aging test which is carried out in the following way: A sample is incubated at a temperature of 50°C and after a specified time interval the soluble stannotin concentration is determined by mixing 1 part of toothpaste with 3 parts distilled water for 10 minutes. The solids are then removed by centrifugation for 30 minutes at 12,000 rpm. my. and the stannotine concentration in an aliquot of the supernatant is determined iodometrically. Another part of the test sample is then adjusted and kept at pH 6.2, mixed with water (1 part paste to 3 parts water) for 1 hour, centrifuged as mentioned above and another analysis for stannotine is carried out. Since increasing the pH to this level results in the dissolution of all of the undissolved portion of the distano salt, the second value provides a measure of the "reservoir" effect of these salts. The results are reproduced below as parts per million soluble stannotin.
Anticariespotensialet for munn- og tannpleiemidlene efter nærværende oppfinnelse ble målt ved"ESR prove" (emaljeoppldsnings-reduksjon). Formålet med denne proven er å bestemme kjemisk reduksjon for oppldseligheten for dentalemalje ved behandling med en opplosning eller behandlingsmiddeloppslemming. The anti-caries potential of the oral and dental care products according to the present invention was measured by the "ESR test" (enamel dissolution reduction). The purpose of this test is to determine the chemical reduction in the solubility of dental enamel when treated with a solution or treatment agent slurry.
Proven utfores på friske mennesketenner, vanligvis jeksler, fortenner og hjørnetenner. Tennene renses og poleres og rottene kuttes derefter av ca. 6 mm under emaljens laveste punkt. The test is carried out on healthy human teeth, usually molars, incisors and canines. The teeth are cleaned and polished and the rats are then cut by approx. 6 mm below the enamel's lowest point.
Hver del av en tann som synes skadet dekkes med blå innleggsvoks. Tennene monteres i hoye begerglass i 180 ml i hvilke bunnen er dekket med blå innleggsvoks. Tennene monteres i dentalsement slik at bare intakt dentalemalje utsettes. Any part of a tooth that appears damaged is covered with blue inlay wax. The teeth are mounted in tall beakers in 180 ml, in which the bottom is covered with blue insert wax. The teeth are mounted in dental cement so that only intact dental enamel is exposed.
Forsøkene utfores i 6 begre med hver 6 tenner. Tennene forberedes ved å innfore ca. 100 ml 0.1-n melkesyre (laktat) buffer ved pH 4.5 i begeret med tennene og rbre om oppløsningen med en konstant hastighet (1725 omdreininger pr., min.) i 2 1-timers perioder og fornye bufringen efter hver 1-times periode. The experiments are carried out in 6 cups with 6 teeth each. The teeth are prepared by inserting approx. 100 ml of 0.1-n lactic acid (lactate) buffer at pH 4.5 in the beaker with the teeth and agitate the solution at a constant speed (1725 rpm, min.) for 2 1-hour periods and renew the buffer ring after each 1-hour period.
Forsøkene utfores med tennene neddykket med omtrentThe tests are carried out with the teeth submerged by approx
sin halve lengde i et vannbad av konstant temperatur på 37°c.half its length in a water bath of a constant temperature of 37°c.
De preparerte tannsett anbringes i klemmer som holder dem iThe prepared dentures are placed in clamps that hold them in place
denne hoyde i badet. Den konstante motorhastighet senkes slik at this height in the bathroom. The constant engine speed is lowered so that
omroringspropellen er ca. 1.25 cm over tennene i begeret, og propellen holdes i denne hoyde under proven. En alikvot del på 40 ml laktatbuffer tilsettes til det monterte tannsett og omroreren startes. Efter 15 minutter fjernes laktatbufferen og bevares for analyse, og de monterte tannsett renses tre ganger i destillert vann og erstattes i vannbad til behandlingstrinnet. the stirring propeller is approx. 1.25 cm above the teeth in the cup, and the propeller is held at this height during the test. An aliquot of 40 ml of lactate buffer is added to the mounted tooth set and the stirrer is started. After 15 minutes, the lactate buffer is removed and preserved for analysis, and the mounted dentures are cleaned three times in distilled water and replaced in a water bath for the treatment step.
En 15 g porsjon av provetannmidlet blandes med ca. 45 ml vann og denne blandingen sentrifugeres i 15 minutter. En alikvot del på 40 ml av den ovenstående væske fra den sentrifugerte tann-middeloppsiemming tilsettes til tennene og omroreren startes. Efter utlbp i 5 minutter stoppes omroringen og behandlingsopplos-ningen fjernes. Tennene renses i destillert vann og tilsettes en annen 40 ml laktatbuffer omrort ved 1725 omdreininger pr. min i 15 minutter. Denne efterbehandlingslaktatopplosning og forbehandlingslaktatopplosning analyseres på fosfor under anvendelse av metoden efter Martin ogDoty. Den prosentvise reduksjon av emalje i opplosningen settes opp som differansen mellom mengden av fosfor i forbehandlingen og etterbehandlingen av laktatbufferopplosningene dividert med mengden av f osf or i for-behandlingskaktatbufferopplosningen. A 15 g portion of the sample dentifrice is mixed with approx. 45 ml of water and this mixture is centrifuged for 15 minutes. A 40 ml aliquot of the supernatant from the centrifuged dentifrice slurry is added to the teeth and the stirrer is started. After running for 5 minutes, the stirring is stopped and the treatment solution is removed. The teeth are cleaned in distilled water and another 40 ml of lactate buffer is added, stirred at 1725 rpm. min for 15 minutes. This post-treatment lactate solution and pre-treatment lactate solution are analyzed for phosphorus using the method according to Martin and Doty. The percentage reduction of enamel in the solution is set up as the difference between the amount of phosphorus in the pre-treatment and post-treatment lactate buffer solutions divided by the amount of phosphorus in the pre-treatment lactate buffer solution.
Sammensetninger av forskjellige tannpastaer efter nærværende oppfinnelse er angitt i tabell I og aldring og ESR data som er oppnådd er gjengitt i tabell 2.Tallene angitt i tabell 1 henviser til konsentrasjon i vektsprosent. De numeriske verdier i tabell 2 (bortsett fra ESR og pH-verdier) angir ppm. av opploselig stannotinn, idet det i fbrste linje for hver tannpasta er angitt mengden ved tannpastaens opprinnelige pH-verdi som er angitt i parentes, og i den andre linje mengden etter innstil-ling til den i samme linje angitte pH-verdi. Compositions of different toothpastes according to the present invention are given in table I and aging and ESR data obtained are given in table 2. The figures given in table 1 refer to concentration in weight percent. The numerical values in Table 2 (apart from ESR and pH values) indicate ppm. of soluble stannate tin, with the quantity at the original pH value of the toothpaste indicated in parentheses indicated in the first line for each toothpaste, and the amount after adjustment to the pH value indicated in the same line in the second line.
Efter aldring ved 50°C gir kontrollpreparatet angitt i tabell 1 de folgende verdier: After aging at 50°C, the control preparation given in table 1 gives the following values:
Det vil sees at Sn (II) nivået i kontrollpreparatet ble redusert med over 50% efter bare 2 dagers lagring. Efter 7 dagers lagring ved 50°C ble Sn (II) nivået for kontrollen redusert til mindre enn 1/10 av sin opprinnelige verdi. En tilsvarende reduksjon iESR-verdien sees ved den lagrede kontrolltannpasta. It will be seen that the Sn (II) level in the control preparation was reduced by over 50% after just 2 days of storage. After 7 days of storage at 50°C, the Sn (II) level of the control was reduced to less than 1/10 of its original value. A corresponding reduction in the ESR value is seen with the stored control toothpaste.
Tannpastaene efter foranstående eksempler gir på den annen side et relativt konstant nivå av Sn (II) efter lagring, selv under disse kraftige lagringsbetingelser selv for lengre perioder (28 dager). ESR-verdiene som vises foran for flere av eksemplene, sees å være i det vesentlige like efter denne lagringsperioden. The toothpastes according to the above examples, on the other hand, give a relatively constant level of Sn (II) after storage, even under these severe storage conditions even for longer periods (28 days). The ESR values shown above for several of the examples are seen to be essentially just after this storage period.
Tannpastaene efter eksemplene IV og v gir betraktelige reduk-sjoner i dental-kalkstensdannelse i sammenligning med kontrollpreparatet når det anvendes på vanlig måte. The toothpastes according to examples IV and v give considerable reductions in dental calculus formation in comparison with the control preparation when used in the usual way.
