Description

DETAILED DESCRIPTION OF THE INVENTION

(1) The use of the pastes by the dentist takes place for example by squeezing the pastes from tubes onto a receiver, from which the paste is taken up by a rotating application instrument with suitable cleaning and polishing attachments (cups, brushes). The rotating instrument attachments thus provided with the pastes are then placed onto the tooth surfaces to be treated, where application of the pastes takes place.

(2) A particularly simple application is evident in a first step from the fact that the pastes can firstly be squeezed out easily, for example from the tubes, but secondly are immediately present in a stable form after being squeezed out, in order to be able to be taken up directly with the application instruments. Here, it is particularly important that the paste does not draw threads when being taken up from the receiver to the applicator. In this stage of the application, the nature of the paste must be such that its cohesive forces are as low as possible and no stickiness arises. In a second step, the stable paste present on the applicator is placed onto the tooth surfaces to be treated, and rotation of the applicator is started. In this stage, the formerly stable paste loses its solidity as a result of the action of shear forces, it begins to flow, builds up high forces of adhesion and now wets the surfaces of the teeth to be treated completely.

(3) The term thixotropically stable is thus understood as meaning that the paste does not per se run, it can be readily taken up with the application tools (cups, brushes) and used in the oral cavity. The pastes only become softer when a shear force as a result of rotating instruments acts upon them during application. However, they also do not run in this situation since they very rapidly revert to the stable state again as soon as rotation subsides or stops.

(4) These properties additionally also prevent a splashing of the pastes during paste application.

(5) An exact measure of the thixotropic stability of the pastes is the value of the so-called spreadability.

(6) Our own extensive studies have revealed that pastes with spreadability values higher than 26 mm are too soft and no longer meet the requirement profile of the property thixotropically stable in the sense used herein.

(7) Pastes with lower spreadability values than 16 mm have proven to be too solid. These also no longer satisfy the requirement profile of the property thixotropically stable in the sense used herein.

(8) Pastes which have a spreadability of from and including 16 mm up to and including 26 mm correspond to the requirements according to the invention placed on the consistency. They have proven to be thixotropically stable in the sense used herein and are therefore optimal for a prophylaxis paste for professional dental use.

(9) The determination of this value is explained in more detail later in the text.

(10) Particularly storage-stable is understood as meaning that the pastes according to the invention, in contrast to the pastes known in the prior art, still have no signs of sedimentation/separation even after storage at highly elevated temperatures of up to 50 C. and varying humidities (rH) between 10% and 75% and prolonged periods of up to 9 months.

(11) Storing of prophylaxis paste compositions was studied at 23 C. and 50% relative humidity (rH), at 40 C. and 75% relative humidity and at 50 C. and 10% relative humidity.

(12) Results of the storage experiments as to stability using the example of a prophylaxis paste with coarse polishing bodies are given below in the experimental section.

(13) Our own extensive studies have revealed that a good measure for predicting the stabilities after natural aging of the pastes is the value of the so-called centrifugal stability.

(14) If, following this method, there are signs of sedimentations and/or separations in the investigated pastes upon visual inspection, the test is classed as not passed, since the homogeneity of the phase is disturbed. If, after the centrifugation, a homogeneous paste is present which has no signs of any kind of separation and/or sedimentation, then the test is passed and the paste is in accordance with the invention or in order (OK). Pastes which pass this test will likewise remain stable following natural storage at elevated temperatures and the corresponding humidities even after aging.

(15) The determination of this value is explained in more detail later in the text.

(16) Surprisingly, it has been found that particularly storage-stable and thixotropically stable dental prophylaxis pastes, which are moreover very easy to use and thoroughly clean and polish the teeth of the patient and cause little abrasion of natural tooth substance can be attained by a paste composition which comprises

(17) a.) a base component comprising water and humectant,

(18) b.) a cleaning body,

(19) c.) a buffer component,

(20) d.) a component for controlling the rheology,

(21) e.) an additive component, where the additives are selected from a list comprising stabilizers, dyes, pigments and fluoridation agents,

(22) where the prophylaxis paste comprises, as cleaning body b.), a compound based on calcium phosphate in combination with pumice and, as wetting agent,

(23) f.) has exclusively one or more amphoteric surfactant(s),

(24) where the buffer component c.) is based on hydrogen phosphate and keeps the pH of the prophylaxis paste, measured in a 10% suspension (w/w) of the paste in water against a pH electrode, between 7 and 8.

(25) Such prophylaxis pastes are characterized in that they are particularly storage-stable, measured according to the method for determining the centrifugal stability, and are thixotropically stable, measured according to the method for determining the spreadability.

(26) These special properties of the prophylaxis pastes can possibly be attributed to synergistic effects between the abrasive substances calcium phosphate and pumice, and also to the use of one or more amphoteric surfactants, the buffer system and the base component. The effect of the synergistic mixture on the stability and the rheological behavior of the paste is possibly further supported through the use of fumed silicas and further binders.

(27) Prophylaxis pastes according to the invention thus have a so-called matrix element in the form of a base component consisting of water and the humectant. All of the components that are soluble in this element, such as the buffer components, surfactant, optionally cellulose derivatives, and additives, for example sodium fluoride, and stabilizers are then dissolved in succession therein and stirred in a kneading pot.

(28) The insoluble components, such as abrasives, pigments, and aerosils are then added to the mixture and processed in a kneader to give a homogeneous mass.

(29) Finally, the paste composition is degassed in vacuo and discharged into tubes, pots or cans.

(30) Specifically, prophylaxis pastes according to the invention can preferably comprise the following components:

(31) Water

(32) Prophylaxis pastes according to the invention are aqueous compositions. The water is preferably prepared, i.e. demineralized, distilled or purified in another way. The amount of water used is 15 to 55% by weight, preferably 20 to 45% by weight and most preferably 23 to 35% by weight, the percentages by weight referring to the total amount of the prophylaxis paste composition.

(33) Humectants

(34) Humectants prevent the pastes from drying out and help to co-regulate the consistency of the pastes and to keep them stable. They also help create (like the surfactants) a suspension.

(35) As a rule, the toxicologically acceptable polyols such as sorbitol, xylitol, glycerol, mannitol, 1,2-propylene glycol, and mixtures of these compounds are used. Although xylitol is also a sweetener, within the context of this invention, this compound is viewed as belonging to the humectants. Polyethylene or polypropylene glycols with average molecular weights of from 200 to 2000 g/mol are also suitable.

(36) According to the invention, preference is given to the combination of glycerol, sorbitol and xylitol.

(37) Depending on the product type, the total composition of the prophylaxis paste comprises the humectant or the mixture of humectants in an amount of from 10 to 60% by weight, preferably from 17 to 50% by weight and most preferably from 25 to 42% by weight. The ratio of humectant to water can be 1:3 to 3:1.

(38) Thickeners (Component for Controlling the Rheology)

(39) Binders and thickeners act as consistency regulators and control the viscosity and consistency of the pastes. In cooperation with the buffer system, the combination and amount of the humectant and the ratio thereof to the amount of water and type and amount of wetting agent, they prevent separation between the liquid and solid phases. In general, for example natural and/or synthetic water-soluble polymers such as alginates, starch and starch ethers, cellulose ethers such as e.g. carboxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellu lose, methylhydroxy-propylcellulose, isopropylcellulose, methylcellulose, and mixtures of these derivatives, agar agar, xanthan, pectins, etc. are used.

(40) Further suitable agents are water-soluble carboxyvinyl polymers, polyvinyl alcohols, polyvinyl pyrrolidones, polyvinyl acetates, polyvinylpyrrolidone-vinyl acetate copolymers, poly(meth)acrylates and poly(meth)acrylic acids, crosslinked poly(meth)acrylates, crosslinked poly(meth)acrylic acids, where the term (meth)acrylates includes both the acrylates and the methacrylates, polyalkylene oxides, polyvinyl alkyl ethers modified with maleic acid, etc.

(41) It is likewise possible to use fumed silicas with a thickening action (which do not belong to the silica polishes). These silicas are preferably organically surface-modified.

(42) According to the invention, preference is given to using fumed silicas and cellulose derivatives.

(43) The amounts of thickeners used in the compositions according to the invention are 0.1 to 7% by weight, preferably 0.1 to 5% by weight and particularly preferably 0.1 to 4% by weight.

(44) Surfactants

(45) Surfactants are added as surface-active wetting agents to the compositions in order to improve the compatibility of the components with one another and to encourage the incorporation of water-insoluble substances, to increase the stability of the pastes and to ensure that the pastes are distributed rapidly and completely during use at the application site, i.e. on the tooth surfaces to be treated, and can thus also reach areas that are difficult to access, for example interdental spaces, so that the effect of the cleaners and of the dental care agents added to the pastes can also develop there. Surfactants assist for example the anticaries effect of fluorides.

(46) According to the invention, the prophylaxis composition is based on the exclusive use of one or more amphoteric surfactants. Within the context of this invention, the term amphoteric surfactant is understood as meaning zwitterionic surfactants which have both a negatively charged functional group and a positively charged functional group. Like all surfactants amphoteric surfactants have a polar and a nonpolar moiety in their molecular structure. The surface-active compounds generally have an alkyl group as nonpolar moiety and at least one quaternary ammonium, phosphonium or sulfonium group and at least one carboxylate, sulfonate, sulfate, phosphate or phosphonate group as polar moiety. The aliphatic group here can be linear or branched, it usually carrying between 8 to 18 carbon atoms.

(47) Surfactants that are particularly suitable for a prophylaxis paste according to the invention are the so-called betaines, such as the N-alkyl-N,N-dimethylammonium glycinates, for example trimethylammonium glycinate, cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinate or N-acylaminopropyl-N,N-dimethylammonium glycinate.

(48) For the use in a prophylaxis paste according to the invention, particular preference is given to the fatty acid derivative known under the name Cocoamidopropyl Betaine, which is commercially available under the name Tego Betain BL 215.

(49) Of most particular preference for the use in a prophylaxis paste according to the invention is 2-[(3-dodecanamidopropyl)dimethylamino]acetate. Further suitable betaines for use in a composition according to the invention can be found in EP 2 198 836 A1.

(50) The amounts of the wetting agent(s) used in the compositions according to the invention are 0.05 to 2.6% by weight, preferably 0.1 to 2.0% by weight and particularly preferably 0.8 to 1.2% by weight.

(51) Buffer Components

(52) A buffer system based on sodium dihydrogen phosphate and disodium hydrogen phosphate is used according to the invention. The buffer system ensures that the pH of the pastes remains stably adjusted between pH=7 and pH=8.

(53) Preferably, the ratio of the amounts of sodium dihydrogen phosphate and disodium hydrogen phosphate used in the compositions according to the invention is 2:1 to 1:2.

(54) Cleaning and Polishing Bodies

(55) Cleaning and polishing agents belong to the most important constituents of a prophylaxis paste. They deal with the mechanical removal of plaque and lead to the shining of the tooth surface with minimal scouring effect and as far as possible no damage to the dental enamel and the dentine. The abrasion behavior of the cleaning and polishing bodies is for the large part determined by their degrees of hardness, particle size distributions and surface properties. When selecting suitable cleaning and polishing bodies, those which have a minimal abrasive effect with a high cleaning performance and a high polishing effect are generally selected.

(56) Cleaning and polishing bodies according to the invention are, for example, calcium phosphates, pumice, so-called silica polishes such as precipitated silicas, gel silicas and hydrogel silicas, also silicates such as aluminum silicates and/or zirconium silicates, mixed silicates such as sodium aluminum silicate of the composition Na.sub.12(AlO.sub.2).sub.12(SiO.sub.2).sub.127 H.sub.2O, synthetic zeolites, aluminum oxides, aluminum hydroxides, such as bentonites, zeolites, kaolin, mica, diatomaceous earth, calcium carbonate, magnesium carbonate, trimagnesium phosphate, polycarbonates, silicon carbide, boron carbide, etc., microcrystalline wax or else composite resins or organic polymers such as melamine resins, phenol resins or urea-formaldehyde resins, etc. According to the invention, preference is given to using water-insoluble inorganic substances, the use of a combination of water-insoluble calcium phosphates being essential to the invention, such as for example the use of the dibasic dicalcium orthophosphate CaHPO.sub.4, the monobasic monocalcium phosphate Ca(H.sub.2PO.sub.4).sub.2, the tribasic tricalcium phosphate Ca.sub.3(PO.sub.4).sub.2, the pentacalciumhydroxy triphosphate (Ca.sub.5(PO.sub.4).sub.3OH), and their hydrates, also of apatite Ca.sub.10(PO.sub.4).sub.6(OH,F,Cl,Br).sub.2 or of Ca.sub.8H.sub.2(PO.sub.4).sub.65 H.sub.2O, where one or more compounds can be used and pumice.

(57) The use according to the invention of a combination of hydroxylapatite and pumice is particularly preferred.

(58) Of several pumice variants investigated, those which have proven to be most advantageous have a fraction of particle sizes of less than 45 m, stated as sieve residue in %, between 50 and 90%, most particularly preferably between 70 and 80%.

(59) The amount of cleaning and polishing bodies used in the overall composition is between 0.5 and 60% by weight and particularly preferably 30 to 36% by weight. Like the selection of the agents and their ratio with one another, this is also dependent on the type of paste.

(60) As described above, dental prophylaxis pastes are generally supplied in three different polishing strengths: one soft, one medium-hard and one hard prophylaxis paste. In the soft polishing and cleaning paste, the ratio of the amount of the cleaning bodies of the compound based on calcium phosphate to pumice is in the range from 40:1 to 10:1 according to the invention.

(61) Here, the RDA value, measured in accordance with DIN EN ISO 11609, should according to the invention be in a range from 5 to 50, preferably in a range from 8 to 30.

(62) In the medium-hard prophylaxis paste, the ratio of the amount of the cleaning bodies of the compound based on calcium phosphate to pumice is according to the invention in a range from 7:1 up to and including 3:1.

(63) Here, the RDA value, measured in accordance with DIN EN ISO 11609, should according to the invention preferably be between 70 and 150, preferably in a range from 100 to 145.

(64) In the hard prophylaxis paste, the ratio of the amount of the cleaning bodies of the compound based on calcium phosphate to pumice is according to the invention in a range from 3:1 to 1:1.

(65) Here, the RDA value, measured in accordance with DIN EN ISO 11609, should according to the invention be in a range from 160 to 250, preferably in a range from 170 to 220.

WORKING EXAMPLES OF THE INVENTION

Determination of the pH

(487) To determine the pH, 2 g of substance are suspended in 20 ml of demineralized water. The pH is then measured against a pH electrode.

(488) Determination of the Spreadability

(489) The determination of the spreadability takes place in a climatically controlled room at a temperature of 23 C. and a relative humidity of 50% by means of a plastic glass plate arrangement. The dimensions of the plates are 60605 mm for a plate weight of 25 g. During the determination, a syringe is used to place 0.5 ml of the respective paste onto the first plastic glass plate in the middle of the plate. The second plastic glass plate is then laid on parallel to the first and weighed down in the middle using a cylindrical iron punch (diameter: 33 mm, height: 13 mm) weighing 100 g for 10 minutes.

(490) After the weighing down, the average of two diameters of the resulting sample cylinder is determined.

(491) This method is a common process for determining the consistency when producing pastes.

(492) Determination of the Centrifugal Stability

(493) To assess the centrifugal stability, 3 g of the respective paste are weighed into a centrifuge glass that has a diameter of 15 mm and a length of 100 mm in a laboratory standard EBA 20 centrifuge from Hettich. The paste is then centrifuged at 5000 rpm for 15 minutes. The temperature during the centrifugal run is 23 C.

(494) RDA Values

(495) The RDA values were ascertained as described above in accordance with DIN EN ISO 11609. The following values were obtained:

(496) TABLE-US-00001 Soft paste RDA value 16 (VC (%) 4.9) Medium-hard paste RDA value 127 (VC (%) 10.1) Hard paste RDA value 195 (VC (%) 2.4)

(497) The examples below serve to illustrate the present invention, but do not limit it in any way.

(498) The preparation of the prophylaxis pastes in the examples shown below for various variations is as follows:

(499) Into a matrix element consisting of water and the humectant are dissolved in succession all of the components that are soluble in this element, the buffer components, surfactant, optionally cellulose derivatives, and additives, for example sodium fluoride and stabilizers, and stirred in a kneading pot. The insoluble components such as abrasives, pigments, and aerosils are then added to the mixture and processed in a kneader to give a homogeneous mass.

(500) Finally, the paste composition is degassed in vacuo and discharged into tubes, pots or cans.

Example 1

(501) Using the example of various soft prophylaxis pastes, the aim is to illustrate the influence of different surfactant types on the physical properties. Here, identical paste formulations are used which differ only in the surfactant type (amphoteric, anionic, cationic).

(503) Surprisingly, it is found that the use of anionic or cationic surfactants leads to considerably different properties compared with the pastes according to the invention.

(504) The prophylaxis paste formulated with an anionic surfactant is extremely soft and exhibits only a very weakly pronounced thixotropically stable behavior corresponding to the value of the spreadability. Additional experiments moreover showed that good wetting of the tooth surface cannot be achieved with this composition.

(505) When using a cationic surfactant, a per se inhomogeneous, likewise very soft prophylaxis paste is obtained. In the centrifuge and during storage, sedimentation of the cleaning bodies very rapidly results. A successful dental prophylactic application is not possible with such a paste system. This is in contrast to the prophylaxis paste according to the invention with an amphoteric surfactant which is characterized by its thixotropically stable behavior with simultaneously good storage stability.

Example 2

(506) Using the example of different hard prophylaxis pastes the aim is to explain what influence different percentage fractions of amphoteric surfactant have in prophylaxis pastes.

(508) It is found that an excessively high or low fraction of amphoteric surfactant leads to a very soft consistency, which is reflected in the values for the spreadability. Additional experiments showed, moreover, that good wetting of tooth surfaces cannot be achieved with these compositions.

(509) In the centrifuge and during storage, sedimentation of the cleaning bodies very rapidly results. Successful dental prophylactic application is not possible with such a paste system.

Example 3

(510) Using the example of different prophylaxis pastes (soft, medium-hard, hard), the aim is to illustrate the influence of the pH on the properties of the pastes. To vary the pH in the pastes, the disodium hydrogen phosphate is kept constant and the content of acidic sodium dihydrogen phosphate is varied.

(515) The variation in the acidic monosodium dihydrogen phosphate leads to a considerable pH fluctuation in the various pastes.

(516) It is found that in the basic range above pH=8 the consistency is very thin and the pastes separate very rapidly, whereas in the acidic range below pH=7 the pastes become very stable and dry. These pastes no longer correspond to the requirement profile according to the invention.

(517) The experiments show that the optimum pH range for the pastes is between 7 and 8. Above this range, in more basic conditions, or below this range, in acidic conditions, the pastes no longer have the properties according to the invention. The optimum pH range can be established precisely by a combination of different amounts of monosodium dihydrogen phosphate and disodium dihydrogen phosphate.

(521) The experiment shows that the prophylaxis paste according to the invention still have no signs of sedimentation/separation even after storage at highly elevated temperatures of up to 50 C. and different humidities (RH) between 10% and 75% and for longer periods up to 9 months. The thixotropically stable properties according to the invention are also retained over the entire period. Prophylaxis pastes from the prior art do not have these properties.
