Description

[Technical Field]

[0001] The present invention relates to a composition particularly suitable as a tooth polishing and cleaning paste. The paste is characterized by having a smooth viscosity and not drying out or deliquescing in the air. [Background technology]

[0002] technical level Bacterial plaque damages the hard tooth and periodontal tissues. Without protective measures, teeth can become demineralized, which ultimately leads to caries. Plaque accumulation above the gum line can also lead to periodontal disease, such as gingivitis, periodontitis, mucositis, or peri-implantitis. Therefore, it is essential to keep the inner surfaces of the mouth as plaque-free as possible. This applies to both natural teeth and teeth that have been restored or replaced with implants.

[0003] In addition to oral hygiene at home using a toothbrush and toothpaste, professional teeth cleaning and polishing contribute significantly to the reduction of biofilm. Professional teeth cleaning includes the removal of supragingival plaque, including tartar, stain removal, and the smoothing and polishing of rough surfaces.

[0004] The polishing and cleaning pastes used for this purpose have a composition similar to regular toothpaste. However, they are not suitable for daily dental care at home because they are designed for the specific requirements of professional tooth cleaning. Profi paste provides maximum cleaning action to effectively remove stains and deposits. Furthermore, after polishing, the surface will be as smooth as possible.

[0005] Profi Paste contains abrasives suspended in a liquid matrix, such as amorphous silicon dioxide, calcium carbonate, calcium phosphate, hydroxyapatite powder, or pumice powder. The matrix typically consists of water, glycerol, polyethylene glycol (PEG), propylene glycol, and similar orally acceptable solvents.

[0006] The enamel of natural teeth is a very hard tissue, and therefore the choice of abrasive is not so critical. In contrast, materials used to repair damaged teeth, such as plastic fillings and dental metal alloys, have much lower hardness and are therefore at risk of scratching if an unsuitable abrasive is chosen. This is not just a cosmetic issue, as scratches make it easier for plaque to accumulate. Other abrasives, such as amorphous silica, are harmless in this regard, but have a much lower cleaning effect and therefore require substantially longer cleaning times to achieve equivalent cleaning results. Stronger stains cannot be removed from the tooth surface with these.

[0007] Toothpaste and profi paste must have a viscosity high enough that the abrasive particles do not settle and the paste can be dispensed onto a toothbrush or dental cleaning and polishing instrument without running off. Thickeners are usually used to set the viscosity. Thickeners are typically synthetic or natural polymers.

[0008] As a general rule, for hygienic reasons, dental profi paste intended for professional use is sold in individual packaging, each containing the amount of product needed for a single application, typically 1.5-2g. The disadvantage is that, due to the small amount of product, once the packaging is opened, the material dries out quickly and becomes difficult to use. Furthermore, for cost reasons, packaging materials that are not completely airtight are often used, resulting in a limited shelf life even for the packaged material. To prevent premature drying, the paste usually contains a water-retaining agent. However, many water-retaining agents are hygroscopic, and as a result, if the surroundings are humid, the product will absorb water. This dilutes the material with water and causes deliquescent properties. Additionally, a liquid film called bleeding can form on the surface of the material, which similarly impairs the processing properties of the paste.

[0009] International Publication No. 2009 / 120854 discloses an oral care product containing a gel network. The gel network refers to a layered or porous solid crystalline phase, which contains an amphiphilic substance, a surfactant, and a solvent. For the formation of the gel network, the amphiphilic substance is dispersed in the solvent together with a dispersing surfactant. The resulting dispersion is then mixed with a swelling surfactant. The addition of the swelling surfactant is said to induce the formation of a gel network, which is said to have a thickening effect. International Publication No. 2010 / 068424 discloses an oral care agent that, in addition to a gel network, contains quartz glass with an average particle size of 3 to 15 μm as an abrasive.

[0012] According to the present invention, this objective is - 1-30 wt%, preferably 5-25 wt%, particularly preferably 10-20 wt% water, - At least one water-retaining agent in an amount of 25-70 wt%, preferably 30-60 wt%, and particularly preferably 30-50 wt%, - At least one abrasive in an amount of 25-60 wt%, preferably 30-55 wt%, and particularly preferably 35-50 wt%, and - At least one surfactant in an amount of 0.05 to 2 wt%, preferably 0.07 to 0.5 wt%, and particularly preferably 0.1 to 0.2 wt% This is achieved by a paste containing [something].

[0013] Unless otherwise indicated, all percentages here refer to the total mass of the paste.

[0014] Remarkably, it was found that Profipaste with the indicated composition can even be stored for longer periods without packaging, without losing its excellent processing properties. They retain a smooth viscosity; that is, they neither dry out nor breathe, and are not diluted with water by absorbing ambient humidity. Furthermore, they allow for quick and gentle cleaning of the tooth surface without damaging restorative materials that are softer than natural tooth enamel. [Modes for carrying out the invention]

[0015] Detailed description of the present invention Abrasive The polishing and cleaning paste according to the present invention contains at least one abrasive in an amount of 25-60 wt%, preferably 30-55 wt%, and particularly preferably 35-50 wt%. The abrasive is preferably selected from kaolin, pumice powder, and silica. A polishing and cleaning paste containing 0-15 wt% kaolin, 0-50 wt% pumice powder, and / or 0-30 wt% silica, with the total amount of abrasive within the given range, is particularly preferred.

[0016] According to the present invention, a composition containing at least 10 wt%, preferably 10 to 50 wt%, and particularly preferably 25 to 35 wt%, of kaolin relative to the total amount of abrasive is indeed very preferred.

[0017] On the one hand, tooth polishing and cleaning pastes efficiently clean the tooth surface while minimizing damage to it. Pumice powder is characterized by its good cleaning action, but due to its strong abrasive properties, it can easily scratch the tooth surface. This is especially true for dental restorative materials made of plastic. In contrast, fumed silica and especially precipitated silica have an amorphous structure and consist of round particles that cause almost no damage, but therefore have low cleaning power and do not remove stains very quickly or efficiently in professional tooth cleaning.

[0018] According to the present invention, it has been found that kaolin powder is remarkably well-suited for cleaning and polishing teeth, enabling efficient yet gentle cleaning of the surfaces of natural and artificial teeth.

[0019] According to the present invention, kaolin that is as pure as possible (CAS number 1332-58-7), particularly preferably having a kaolin content of more than 90 wt%, more preferably more than 98 wt%, and most preferably about 99 wt%, is preferably used. The kaolin preferably contains less than 1 wt% crystalline silicon dioxide (quartz). In a particularly preferred embodiment, pharmaceutical-grade kaolin is used.

[0020] Furthermore, kaolin powder having an average particle size (D50) of 1 to 20 μm, particularly preferably 2 to 15 μm, and especially preferably 3 to 10 μm, is preferred. Moreover, kaolin powder containing as few coarse particles as possible is preferred. The proportion of coarse particles is characterized by the D90 value. Kaolin powder having a particle size (D90) of less than 30 μm, preferably less than 20 μm, and particularly preferably less than 15 μm, is particularly suitable according to the present invention. Powders having D50 and D90 values ​​within the given ranges enable very gentle cleaning of the tooth surface without damaging the restorative material.

[0021] Unless otherwise specified, the particle size distribution of the powder is measured using a laser diffraction particle size analyzer. The D50 value characterizes the average particle size distribution by volume, and the D90 value characterizes the proportion of coarser particles in the powder. A D50 value means that half of the powder volume is greater than the indicated value, and a D90 value means that only 10% of the powder volume is greater than the indicated value.

[0022] Unless otherwise specified, all particle sizes are volume diameters, and particle size determination in the range of 0.1 μm to 1000 μm is preferably performed by static light scattering using, for example, an LA-960 static laser scattering particle size analyzer (Horiba, Japan). Here, a laser diode with a wavelength of 655 nm and an LED with a wavelength of 405 nm are used as light sources. The use of two light sources with different wavelengths makes it possible to measure the entire particle size distribution of the sample in only one measurement pass, and the measurement is performed as a wet measurement. For this purpose, a 0.1-0.5% aqueous dispersion of the filler is prepared, and its scattered light is measured in a flow cell. Analysis of the scattered light for calculating particle size and particle size distribution is performed according to the Mie theory according to DIN / ISO 13320. Particle size measurements in the range of 5 nm to 0.1 μm are preferably performed by dynamic light scattering (DLS) of an aqueous particle dispersion using a He-Ne laser with a scattering angle of 90° and a wavelength of preferably 633 nm at 25°C, for example, using a Malvern Zetasizer Nano ZS (Malvern Instruments, Malvern UK).

[0023] The profi paste according to the present invention preferably contains kaolin powder having a D50 value of 1 to 20 μm and a D90 value of less than 30 μm, preferably a D50 value of 2 to 15 μm and a D90 value of less than 20 μm, and particularly preferably a D50 value of 3 to 10 μm and a D90 value of less than 15 μm.

[0024] In addition to kaolin, the polishing and cleaning paste according to the present invention further contains additional abrasives. Inorganic powders, such as calcium carbonate, calcium phosphate, aluminum oxide, and aluminum hydroxide hydrate [AlO(OH)·H2O], are particularly suitable as additional abrasives. Pumice powder and synthetic and naturally modified silicon dioxide are particularly preferred. Diatomaceous earth, which is a naturally occurring form of silicon dioxide, is preferred. Fumed silica and particularly precipitated silica are preferred examples of synthetic silicon dioxide modified products. Precipitated silica having an average particle size (D50) of 5-15 μm and a D99 value of <30 μm, particularly preferably <25 μm, is particularly preferred.

[0025] A mixture of kaolin powder and silica, and more particularly a mixture of kaolin powder and precipitated silica (INCI name: hydrated silica), is preferred according to the present invention. It has been found that good tooth polishing can be achieved significantly more quickly with a paste containing a mixture of silica and kaolin than with a paste containing amorphous silica alone. Nevertheless, the paste is also equally gentle with respect to dental plastic materials. A mixture containing 20-40 wt%, particularly preferably 24-36 wt%, and most preferably 26-34 wt%, of the total amount of kaolin and silica is indeed particularly preferred.

[0026] Prophy paste with higher abrasive properties can be prepared by adding pumice powder. Pumice is a porous, glassy volcanic rock. In chemical terms, pumice is amorphous aluminum silicate with a Mohs hardness of 6. Pumice powder, also abbreviated as pumice powder, is a finely ground powder made from pumice. Because pumice powder has a hardness comparable to tooth enamel, it is well suitable for removing deposits from the surface of natural or ceramic teeth. Pumice powder having an average particle size (D50) of 10-60 μm, particularly 15-50 μm, and especially 15-40 μm, is preferred according to the present invention. In the case of pumice powder, it is especially important that the coarsest particles are not too large, as these particles cause the deepest scratches. The D99 value can be used as a measure of the coarsest particles, meaning that 99% of the particles are smaller than the given value. Pumice powder having a D99 value of <200 μm, particularly preferably <150 μm, and especially preferably <120 μm is preferred.

[0027] The abrasive properties of profi paste can be targeted by mixing different abrasives. Profi paste containing pumice is particularly suitable for removing stains from teeth. Pastes containing silica and pumice powder, kaolin, a mixture of silica and pumice powder, or a mixture of kaolin and silica are preferred. Pastes containing only kaolin powder and, optionally, silica as an abrasive are particularly preferred, and in all listed cases, precipitated silica is preferred as silica. Water-retaining agent

[0028] The polishing and cleaning agent according to the present invention contains at least one water-retaining agent in an amount of 25-70 wt%, preferably 30-60 wt%, and particularly preferably 30-50 wt%.

[0030] A composition containing 18-50 wt%, particularly preferably 25-46 wt%, and indeed most preferably 30-44 wt%, of glycerol is preferred.

[0031] A composition further containing 1-5 wt% xylitol and / or 1-5 wt% sorbitol in addition to glycerol is particularly preferred, and the total amount of xylitol and sorbitol is preferably within the range of 1-5 wt%.

[0032] The amount of water-retaining agent is preferably selected such that the weight ratio of water to the total amount of water-retaining agent is within the range of 0.05 to 0.6, particularly preferably 0.25 to 0.5, and especially preferably 0.30 to 0.40. surfactants

[0040] A particularly preferred embodiment of the present invention is a profi paste containing 0.1 to 0.2 wt% sodium lauryl sulfate, cetylpyridinium chloride, or dodecyltrimethylammonium chloride. Thickening agent

[0041] To set the viscosity, the profi paste according to the present invention preferably also contains a thickening agent.

[0042] According to one embodiment, the paste contains at least one natural or synthetic polymer having thickening properties as a thickening agent. Preferred polymers are homopolymers (carbomers) of carboxymethylcellulose, hydroxyethylcellulose, methylcellulose, guar gum, carrageenan, xanthan gum, and acrylic acid. Carbomers, carboxymethylcellulose, hydroxyethylcellulose, and xanthan gum are particularly preferred polymers. Carbomers are preferably used together with a neutralizing agent. Preferred neutralizing agents are sodium or potassium hydroxide solution, ammonia, arginine, aminomethylpropanol, tetrahydroxypropylethylenediamine, (ethylenedinitrilo)tetra-2-propanol, triethanolamine, tromethamine, PEG-15 cocamine, diisopropanolamine, and triisopropanolamine.

[0043] The Profi Paste according to the present invention has a relatively low water content. However, many polymer thickeners are water-soluble and therefore require a high water content. Carbomer, xanthan gum, and hydroxyethylcellulose can be used in anhydrous compositions or compositions having a low water content.

[0044] The polymer thickener is preferably used in an amount of 0.2 to 2 wt%, particularly preferably 0.4 to 1.5 wt%, and especially preferably 0.5 to 1.0 wt%.

[0045] According to a preferred embodiment, the profi paste according to the present invention contains at least one fatty component for thickening. The fatty component is used in an amount of preferably 0.5 to 3 wt%, particularly preferably 0.7 to 2.2 wt%, and indeed most preferably 1 to 1.3 wt%. The fatty component results in thickening of the paste through interaction with the surfactant, water, and water-retaining agent. The paste may further contain a polymer thickener, but a paste without a polymer thickener is preferred.

[0046] The fatty component and surfactant are preferably used in a ratio of fatty component to surfactant in the range of 20 to 1.4, preferably 12 to 4, and most preferably 10 to 4.

[0047] In each case, organic compounds having water-miscible hydrocarbons and hydrocarbon radicals containing carbon chains with at least 12, and very preferably at least 14, carbon atoms are particularly suitable as fatty components. Hydrocarbons and hydrocarbon radicals containing carbon chains with 12 to 30, particularly preferably 12 to 28, very preferably 14 to 24, and most preferably 16 to 22 carbon atoms are preferred. Preferred fatty components are fatty alcohols. Fatty alcohols having chain lengths of 12 to 22, particularly 14 to 22 carbon atoms are very preferred. Fatty alcohols containing 16 to 18 carbon atoms are most preferred. Very particularly preferred fatty alcohols are lauryl alcohol, particularly cetyl alcohol and stearyl alcohol. Different fatty components, particularly mixtures of different fatty alcohols, can also be used. A preferred mixture is a mixture of cetyl and stearyl alcohol, also called cetylstearyl alcohol below, particularly preferably a mixture of approximately 1:1.

[0048] The fatty component is preferably solid at room temperature, particularly preferably has a melting point of ≥24°C, and more preferably >40°C. A fatty component having a melting point of 45-60°C is most preferred.

[0049] The preferred fatty component according to the present invention is characterized in that it also has excellent thickening properties, especially when it has a low water content. metal oxides

[0050] The Prophy Paste according to the present invention preferably contains at least one metal oxide. The metal oxide is preferably an oxide of a metal in Group 4 of the periodic table and an oxide of a tetravalent metal (Me IV Selected from O2), mixed oxides are preferably excluded. Zirconium and titanium oxides are particularly preferred.

[0051] The oxide of a tetravalent metal (Me IV O2) is particularly preferred, and zirconium oxide, especially titanium dioxide, is truly particularly preferred. Anatase is most preferred. Anatase is one of three TiO2 modifications. The other two modifications are rutile and brookite. The metal oxide is preferably not surface-modified. The metal compounds cited are characterized by an extremely polar surface.

[0052] Surprisingly, it has been found that the addition of the cited metal oxides can significantly reduce or even completely prevent the formation of a liquid film on the surface of the paste, i.e., bleeding of the paste, even in the case of storage at 40 °C and 75% RH. The paste remains homogeneous even with changes in ambient humidity. This is particularly true for pastes containing a fatty component as a thickener. The exact cause of this effect is unknown. Preventing the bleeding of dental pastes by using metal oxides is the subject of the present invention.

[0053] The oxide of a Group 4 metal is preferably used in an amount of 0.05 to 3 wt%, particularly preferably 0.5 to 3 wt%, and truly particularly preferably 0.5 to 1.5 wt%. Additives and adjuvants

[0054] In addition to the components cited, the prophylaxis paste according to the invention advantageously contains one or more adjuvants, such as fluoride-releasing additives, flavoring agents, sweetening agents, dyes, stabilizers and agents for preventing the growth of microorganisms.

[0055] Preferred fluoride-releasing additives include fluoride compounds, particularly sodium fluoride, potassium fluoride, ammonium fluoride, ammonium hydrogen fluoride, sodium monofluorophosphate, potassium monofluorophosphate, calcium fluoride, and salts of tetra or hexafluoroanions, such as ammonium hexafluorosilicate, magnesium hexafluorosilicate, potassium hexafluorophosphate, ammonium hexafluorotitanate, ammonium tetrafluorotitanate, ammonium hexafluoroaluminate, zirconium fluoride, tetra-n-butylammonium trifluoride (TBAF-3), rubidium fluoride, cesium fluoride, potassium hydrogen fluoride (KHF2), silver(I) fluoride (AgF), tin(II) fluoride (SnF2), olaflur, and dectaflur. The following are particularly preferred: sodium fluoride, potassium fluoride, sodium monofluorophosphate, tin(II) fluoride (SnF2), ammonium fluoride, olaflur, and dectaflur.

[0056] The fluoride component is preferably used at a concentration of 0 to 20,000 ppm, particularly preferably 100 to 5,000 ppm, and especially preferably 500 to 1,500 ppm. These values ​​relate to the amount of fluoride ions in the entire composition.

[0057] Flavorings impart the desired taste to the profi paste. Preferred flavorings are natural or artificial compositions having peppermint, strawberry, raspberry, banana, lemon, bubble gum, or apple flavors. Profi paste may contain one or more flavorings.

[0058] The profi paste according to the present invention may further contain one or more sweeteners. Preferred sweeteners are acesulfame, aspartame, cyclamate, neohesperidin, sugar, sucralose, and stevioside. Sugar alcohols such as xylitol, erythritol, and sorbitol can also be used as sweeteners, but they are required in relatively large quantities. water activity

[0059] The dental profi paste according to the present invention is characterized by its ability to maintain its smooth viscosity even under unfavorable ambient weather conditions and not dry out even when not packaged in an airtight manner. This is achieved by harmonizing the types and amounts of components used in a manner advantageous to the paste according to the present invention. It has been found that the profi paste has particularly good properties when the types and amounts of components are selected such that the paste has a water activity in the range of 0.5 to 0.7, preferably 0.5 to 0.65, and especially preferably 0.55 to 0.65, measured at a temperature of 25°C in each case.

[0060] Water activity at a given temperature (a w The water activity of the paste is defined as the ratio of the partial pressure of water vapor of the compound to the saturated vapor pressure of pure water. The water activity of the paste is determined by placing 3 g of Profi paste into an airtight, sealable chamber with a volume of 15 ml, and then measuring the humidity established in the sealed residual air. Humidity is measured in % relative humidity (RH) and is as follows: w Regarding the value: a w =RH / 100. The measurement is preferably performed using a commercially available measuring device, such as the LabTouch-aw advanced model (Novasina AG, Neuheimstrasse 12, CH-8853 Lachen).

[0061] By setting the water activity, it becomes possible to provide a reproducible paste with desired properties. The water activity can be set particularly well by changing the amounts of water-retaining agent and water. These amounts are preferably selected so that the water content is in the range of 20-30 wt%, preferably 22-29 wt%, and particularly preferably 24-28 wt%, relative to the total amount of water and water-retaining agent. disc consistency

[0062] The paste according to the present invention is characterized by a creamy, smooth viscosity, which ensures that the paste according to the present invention can be easily dispensed from a tube and has good spreadability. Thus, the paste according to the present invention can be easily scooped up with a dental rubber cup or polishing brush and spread on the teeth. A rubber cup is a rotating dental instrument in the form of a hollow cylinder. Rubber cups are used with a rotating handpiece to clean and polish teeth. Rubber cups are typically applied with a contact pressure of approximately 2N and a rotational speed of 2,000 to 10,000 revolutions per minute.

[0063] Disk viscosity is used as a measure of the viscosity of a paste. To measure disk viscosity, a predetermined amount (0.70 ± 0.01 g) of sample, at a precise temperature (23 ± 2 °C), is compressed between two square glass plates (approximately 0.7 mm thick, with sides approximately 50 mm long) under a predetermined test load (120 g) for 3 minutes at 23 ± 2 °C. The diameter of the compressed sample ("disk diameter") is then measured with an accuracy of 0.01 mm. The diameter in millimeters corresponds to the disk viscosity.

[0064] The paste according to the present invention preferably has a disc viscosity of 20 to 40 mm, particularly preferably 25 to 38 mm, and very preferably 28 to 35 mm. liquidity

[0065] The Profi Paste according to the present invention is further characterized by its good creep strength, which prevents it from flowing out of dispensers such as finger clips. A finger clip is a small container with a volume of approximately 2 ml and can be worn on a finger using a holder.

[0066] To measure fluidity, a predetermined amount (1.5±0.05g) of sample, heated to a precise temperature (23±2℃), is spread in a circle (approximately 2cm in diameter) on a mixing block (HDPE-based synthetic paper, e.g., Polyart®, manufactured by Arjobex, Boulogne-Billancourt, France). The mixing block containing the sample is then left to stand horizontally at 23±2℃ for 15±0.5 minutes, and then placed vertically. After 15±0.5 minutes, the amount of downward movement of the leading edge of the paste is measured. The paste according to the present invention preferably flows to less than 10mm, particularly preferably less than 3mm, and very particularly preferably less than 1mm.

[0067] According to the present invention, the following composition: - 1-20 wt%, preferably 1.5-16 wt%, particularly preferably 12-16 wt% water, - 13-46 wt%, preferably 25-46 wt%, particularly preferably 30-40 wt% glycerol, - 0-25 wt%, preferably 1-10 wt%, particularly preferably 1-5 wt%, xylitol and / or sorbitol, - 0-45 wt%, preferably 10-43 wt%, particularly preferably 12-22 wt% kaolin, - Precipitated silica of 0-40 wt%, preferably 0-28 wt%, particularly preferably 20-28 wt%, - 0.05 to 2 wt%, preferably 0.1 to 0.5 wt%, particularly preferably 0.1 to 0.2 wt%, sodium lauryl sulfate, and - 0.5 to 3 wt%, preferably 0.7 to 2.0 wt%, and particularly preferably 1 to 1.3 wt%, of cetyl alcohol, stearyl alcohol, or mixtures thereof. A Profi paste having the above is particularly preferred, and the total amount of abrasive is included in the range of 36 to 51 wt%.

[0068] In a particularly preferred embodiment, the paste is - 0.5~3.0 wt%, preferably 0.7~2.5 wt%, particularly preferably 1.0~2.0 wt% of Me IVO2, especially TiO2, ZrO2, or combinations thereof. It further contains

[0069] The following composition: - 12-16 wt% water, - 30-40 wt% glycerol, - 1-2 wt% xylitol, - 1-3 wt% sorbitol, - At least one abrasive selected from 12-22 wt% kaolin, 20-28 wt% precipitated silica, and 20-50 wt% pumice powder. - 0.1~0.2 wt% sodium lauryl sulfate, and - 1-1.3 wt% cetyl alcohol, stearyl alcohol, or mixtures thereof - 1.0-2.0 wt% TiO2, ZrO2, or a mixture thereof A profi paste having the above is even more preferable, and the total amount of abrasive is in the range of 36 to 51 wt%.

[0070] In all cases, the preferred and particularly preferred ranges listed herein can be selected independently of each other. Preparation method

[0071] The profi paste according to the present invention can be prepared in its simplest form by homogeneously mixing the individual components with each other.

[0072] A paste containing a fatty component as a thickening agent is preferably prepared by first taking water and a portion of a water-retaining agent, preferably water and glycerol, and then suspending an abrasive in it. Color and flavor components, as well as further additives as needed, such as fluoride components, may also be incorporated into this suspension.

[0073] In a separate container, mix the fatty components with the water, the remaining water-retaining agent, and the surfactant, and heat until the fatty components are completely melted. Continue mixing until a homogeneous mixture is formed.

[0074] Next, the mixture of fatty components is added to the abrasive-containing suspension and mixed until homogeneous. To prevent the incorporation of air, mixing is preferably carried out under reduced pressure. A creamy, smooth, and creep-stable paste is obtained.

[0075] The individual components of the paste according to the present invention are preferably divided into two mixtures such that the weight ratio of the abrasive-containing suspension to the mixture containing the fatty component is in the range of 95:5 to 50:50, with a ratio of 90:10 being particularly preferred.

[0076] The polishing and cleaning paste according to the present invention is particularly suitable for professional dental cleaning, i.e., professional cleaning and polishing of natural teeth, restorations, and dentures. Profi Paste is suitable for removing plaque and external stains from teeth, minimizing plaque buildup and retention. For gentle cleaning of natural teeth, especially teeth restored with relatively soft fillings, it is important that Profi Paste does not damage the tooth surface. Conventional polishing pastes with high cleaning power usually also have high abrasiveness, which increases the risk of damage. Conversely, low abrasiveness is typically accompanied by low cleaning power, which increases the time required for cleaning teeth. Currently, in professional dental cleaning, as a rule, teeth are first treated with a paste with high cleaning power, and finally polished with a paste with low abrasiveness to smooth the tooth surface. Profi Paste according to the present invention has polishing and cleaning properties that are advantageous for dental purposes without damaging ordinary plastic fillings and dental metals. Therefore, the Profi Paste according to the present invention makes it possible to clean and polish the tooth surface in a single operation.

[0077] Furthermore, its viscosity and creep strength ensure that the profi paste according to the present invention does not run or drip from cleaning instruments such as brushes or rubber cups within a short time. Therefore, the profi paste according to the present invention is easy to handle and allows for efficient cleaning of both the surface of natural teeth and the surface of restored teeth.

[0078] Furthermore, this paste will not dry out in a dry environment, even when stored open or in inadequately airtight packaging. It will not breathe in a humid environment and will not begin to run when it absorbs moisture. It remains creamy and smooth, making it suitable for use in many climate zones.

[0079] The Profi Paste according to the present invention may be sold in packaging in tubes or cans. A single-dose package containing the amount of Profi Paste required for a single application, particularly about 1-2 ml, is preferred. After filling, a plastic container, particularly a deep-drawn plastic container, sealed with plastic, aluminum, or a plastic / aluminum laminate film, is preferably used as packaging. The plastic container is preferably made from a composite material made of polyethylene, polyamide, polypropylene, polystyrene, polyvinyl chloride, or various other plastics.

[0080] According to the present invention, the teeth are preferably prepared in the following steps: (1) If necessary, preferably using a scaler or airflow device, the step of removing tartar and / or plaque from the teeth. (2) Preferably using a rubber cup or rotary brush, a step of applying a portion of the Profi Paste according to the present invention to the surface of the tooth, (3) The step of polishing the teeth using a cup or brush at a speed of preferably 100 to 10000 rpm, more preferably 500 to 5000 rpm, and most preferably 2000 to 3000 rpm. (4) If necessary, rinse your teeth with water to remove any paste residue. It is cleaned by a method that includes [a specific method].

[0081] In step (1), sodium bicarbonate, particularly glycine or erythritol, is preferably used as an abrasive powder for the airflow treatment.

[0082] In step (3), the teeth are polished for preferably 1 to 60 seconds per tooth, more preferably 2 to 10 seconds, and most preferably 2 to 5 seconds.

[0083] According to a preferred embodiment of the present invention, steps (2) and (3) are performed only once each, i.e., only one type of profi paste is used for cleaning the teeth. As mentioned above, it is standard practice for professional teeth cleaning to use two or more types of paste. By using the profi paste according to the present invention, only one polishing step is required, which represents a considerable simplification of the cleaning process and reduces the time required.

[0084] The above method is suitable for cleaning natural teeth and dental restorations. However, in contrast to natural teeth, many dental restorations and restorative materials, such as composites, resin dentures, dental alloys, titanium, implants, and implant abutments, are quite soft. Therefore, as described above, to clean such restorative materials and restorations made from them, it is preferable to avoid using scalers and airflow devices, especially airflow devices, with highly abrasive powders such as sodium bicarbonate in step (1), and in step (2), a profi paste containing only kaolin and / or silica as an abrasive is preferably used. These abrasives have been found not to damage soft dental restorative materials.

[0085] The present invention will be described in more detail below with reference to the figures and examples. [Brief explanation of the drawing]

[0086] [Figure 1]Figure 1 shows the abrasive properties (cleaning powder) of different Profi pastes. As abrasives, paste R1-108 contains only precipitated silica, and paste R3-27 contains only kaolin. The residual paste contains a mixture of precipitated silica and kaolin with different particle sizes. It can be seen that the cleaning power of the paste increases with partial or complete substitution of precipitated silica with kaolin. The abrasive properties increase as the particle size of the kaolin used increases. [Figure 2] Figure 2 shows the polished surface of a commercially available plastic filler. The surface is smooth and free of visible scratches. [Figure 3] Figure 3 shows the plastic filler from Figure 2 after treatment with conventional abrasive paste. This paste left obvious scratches on the surface. [Figure 4] Figure 4 shows the plastic filler from Figure 2 after treatment with the polishing paste according to the present invention, which contains a mixture of kaolin and precipitated silica as abrasives. The plastic surface is free of visible scratches. [Figure 5] Figure 5 shows a scanning electron microscope image of a polished titanium surface. The surface is smooth and free of scratches. [Figure 6] Figures 6-9 show scanning electron microscope images of titanium surfaces as shown in Figure 5, which have been treated with conventional polishing paste (Figures 6-8) or the polishing paste according to the present invention (Figure 9). The paste according to the present invention leaves no scratches on the titanium surface, while the surface treated with the conventional paste clearly has visible scratches. [Figure 7] Figures 6-9 show scanning electron microscope images of titanium surfaces as shown in Figure 5, which have been treated with conventional polishing paste (Figures 6-8) or the polishing paste according to the present invention (Figure 9). The paste according to the present invention leaves no scratches on the titanium surface, while the surface treated with the conventional paste clearly has visible scratches. [Figure 8]Figures 6-9 show scanning electron microscope images of titanium surfaces as shown in Figure 5, which have been treated with conventional polishing paste (Figures 6-8) or the polishing paste according to the present invention (Figure 9). The paste according to the present invention leaves no scratches on the titanium surface, while the surface treated with the conventional paste clearly has visible scratches. [Figure 9] Figures 6-9 show scanning electron microscope images of titanium surfaces as shown in Figure 5, which have been treated with conventional polishing paste (Figures 6-8) or the polishing paste according to the present invention (Figure 9). The paste according to the present invention leaves no scratches on the titanium surface, while the surface treated with the conventional paste clearly has visible scratches. [Figure 10] Figure 10 shows conventional profi paste and profi paste according to the present invention after removal from the container. Product Proxyt RDA 7 fine and pastes R6-65 and R6-75 according to the present invention have a plastic, paste-like viscosity. The remaining products have a crumbly viscosity and had to be removed from single-dose packaging using a spatula. [Examples]

[0087] (Example 1) Preparation and testing of Profipaste For the preparation of the pastes described in Table 1, most of the water and glycerol were placed in a mixing apparatus, and the abrasive was suspended therein. The additive was then mixed. In a separate heat-sensitive mixing apparatus, the fatty alcohol and surfactant were mixed with the remainder of the water and water-retaining agent, and heated until the fatty alcohol was completely dissolved. Mixing was continued until a homogeneous mixture was formed. During the process, the fatty alcohol was emulsified in the polar phase by the surfactant. The mixture of fatty alcohols was then added to the suspension from the first step and mixed under reduced pressure.

[0088] All formulations in Table 1 exhibit viscosity and flow behavior suitable for dental profi paste. Table 1 shows that pastes with high water activity dry quickly and are then unusable (R3-88). Water activity, disc viscosity, and flowability were measured as described above. In the case of low water activity, the paste behaves hygroscopically, absorbing water from ambient humidity, which impairs the processing properties of the paste (R1-108, R3-89). In the case of pastes R1-108 and R3-89, water absorption results in the formation of a liquid film on the surface of the material, which impairs the processing properties of the material. Only pastes R3-52, R3-53, and R3-27 exhibit slight bleeding, and in the case of pastes N1-152, R6-65, R6-75, R3-54, R3-80, and R6-73, bleeding decreases further.

[0089] A comparison of pastes R3-89 and R3-54 shows that bleeding is particularly effectively prevented when the water activity is greater than 0.5 and the paste contains metal oxides. [Table 1-1] [Table 1-2]

[0090] The water absorption and loss of the paste were determined under extreme environmental conditions. Therefore, the increase or loss in paste weight was quantified under dry storage at room temperature (23±2°C, RT) and approximately 10% relative humidity (RH), or under tropical conditions (40°C, 75% RH). Dry storage was performed in a dehydrator on lithium chloride. A digital hygrometer was placed in the dehydrator to track drying. Samples were stored in the dehydrator until an equilibrium moisture content of approximately 10% was established, which typically occurred after 10–14 days. Storage under tropical conditions was performed in a climate cabinet with temperature and humidity control. Samples were stored under these conditions for approximately two weeks, during which time the moisture content reached environmental equilibrium. Measurements for two types of paste are shown as an example in Table 2.

[0091] The Prophy pastes listed in Table 2 have a water activity of 0.56 and hardly bleed even at a humidity of 75% RH. The difference in weight change observed is negligible. Both pastes absorb and release approximately the same amount of moisture from the environment. Paste R3-54 is characterized by not bleeding at all compared to paste R3-52. This is attributable to its titanium dioxide content. When stored at room temperature (10% RH), the paste became more solid but could still be easily scooped with a dental rubber cup and used without limitations. Even after storage at 40°C (75% RH), the paste remained smooth, could still be easily scooped with a rubber cup and used without limitations. [Table 2]

[0092] (Example 2) Measurement of the polishability of Profi Paste To determine the abrasive properties (cleaning power) of the paste, a pure copper cylinder (25 mm in diameter) was polished with the paste, and the amount of material removed was measured. Pure copper is softer than dental plastic fillings and common dental alloys. The method allows for the measurement of abrasive properties under reproducible conditions in the laboratory. A commercially available grinder and polisher was used (Buehler EcoMet250 with AutoMet250 grinding head). A 10-inch (25.4 cm) diameter polishing cloth (TexMet C type; Buehler, Lake Bluff, IL, USA Art.40-1110) was coated with a thin layer (approximately 15 g) of the profi paste to be tested using a spatula. The copper cylinder was then polished for 5 minutes using the grinder without water cooling under the following conditions: • Head speed: 30 rpm · Basic speed: 100rpm • Single-stroke abrasive pressure: 20N • Downward / Upward grinding: Downward

[0093] Profi pastes with and without kaolin (paste R1-108*) and with kaolin (pastes R3-53, R3-52, and R3-27) were compared. The pastes contained kaolin with different particle sizes. Abrasion of copper test specimens was quantified by determining the weight difference before and after polishing using an analytical balance. Figure 1 shows the abrasiveness of the tested profi pastes. It can be seen that the abrasiveness, and therefore the cleaning power, of the profi paste increases by partially or completely replacing precipitated silica with kaolin. The abrasiveness increases as the average particle size of the kaolin used increases. (Example 3) Determination of the scratch properties of Profipaste against plastic fillers

[0094] The scratch behavior of the polishing paste according to the present invention was compared with that of commercially available products. For this purpose, a composite filler (A3 color Tetric Prime; Ivoclar Vivadent AG, Schaan, Liechtenstein) was polymerized according to the manufacturer's instructions, then ground, and finally polished with 4000-grit silicon carbide paper while water-cooled. Figure 2 shows the polished surface of the plastic filler. A smooth, scratch-free surface is observed.

[0095] Next, the smooth surface was polished using a dental rubber cup with commercially available polishing paste (Nupro Fine, Dentsply Professional, York PA, USA, Article Number 801232, Lot: 00022171) for 10 seconds at a grinding pressure of 2N and a rotation speed of 3000 rpm. This product left noticeable scratches on the surface (Figure 3).

[0096] For comparison, a smooth surface of a composite filler was treated with paste R6-65 according to the present invention using the method described. Figure 4 shows that the polishing paste according to the present invention, which contains a mixture of precipitated silica and kaolin as abrasives, did not leave scratches on the plastic surface.

[0097] The results of Examples 2 and 3 demonstrate that the Profi Paste according to the present invention possesses abrasive and cleaning properties advantageous for dental purposes without damaging conventional plastic fillings. The kaolin-containing paste is as gentle as precipitated silica but achieves a much better cleaning effect, resulting in a much shorter cleaning procedure time. (Example 4) Scratch properties of ProfiPaste on dental titanium

[0098] Grade 5 titanium is used to manufacture implant abutments. These components are also placed in the oral cavity and must be kept clean. Many metals, especially Grade 5 titanium, are more fragile than dental plastic fillings, and a particularly gentle technique is required here to avoid damaging the surface.

[0099] To compare the scratch properties of the polishing paste according to the present invention with those of commercially available materials, Grade V titanium was polished. For this purpose, a round titanium disc (19 mm in diameter, 2.25 mm thick) was embedded in GTS polystyrene casting resin. The disc was then wet-grinded with 4000-grit silicon carbide paper and then polished to a high gloss using a polishing cloth (Chemomet Polishing Cloth Art. 40-7920, Buehler, LakeBuff, IL, USA) and a series of abrasives (1. Buehler MasterPrep Polishing Suspension 0.05 μm, Art. 40-6377-032; 2. Buehler MasterMet Colloidal Silica Suspension, Art. 40-6370-006; 3. Buehler MasterMet 2 Non-crystallizing colloidal silica Polishing suspension, Art. 40-6380-006). In each step, the disc was polished at 100 rpm and a grinding pressure of 20 N for 10 minutes, and only in the final step at 15 N. Figure 5 shows a scanning electron microscope image of the polished surface. The surface is smooth and free of scratches.

[0100] Next, the titanium surface was polished with the paste to be tested for 10 seconds and under a grinding pressure of 2N using a dental rubber cup at 3000 revolutions per minute. The following materials were used: - Nupro Fine (Dentsply Professional, York PA, USA, Article Number 801232, Lot: 00022171; Figure 6) - Cleanic (KerrHawe SA, Bioggo, Switzerland, Article Number 3140, Lot:7251052; Figure 7) - Clinpro (3M Oral Care Solutions Division, St.Paul MN, USA, Article Number 12613, Lot:091119A; Figure 8)

[0101] Figures 6-8 show the surface of the titanium disc after processing. In all cases, the product had noticeable scratches on the surface.

[0102] For comparison, a titanium surface was treated with paste R6-65 according to the present invention using the method described. Figure 9 shows that the polishing paste according to the present invention left no scratches on the titanium surface. (Example 5) Comparison of viscosity between the paste according to the present invention and a commercially available product.

[0103] Most commercially available profi pastes are sold in small individual packets and contain only a small amount of water. They have a relatively firm viscosity. Examples include the products Nupro (Dentsply Professional, York PA, USA), Clinpro (3M Oral Care Solutions Division, St. Paul MN, USA), and Cleanic (KerrHawe SA, Bioggo, Switzerland). The product Proxyt RDA 7 fine (Ivoclar Vivadent AG, Schaan, Liechtenstein) is supplied in a tube.

[0104] Figure 10 shows the products listed above after being removed from their containers. Only Proxyt RDA 7 fine is a plastic paste-like substance. The other products had to be removed from their single-dose packaging using a spatula. They are difficult to scoop with a rubber cup.

[0105] Profi Paste R6-65 (Lot: YM1278) and R6-75 according to the present invention are also shown for comparison. Like the product Proxyt RDA 7 fine, pastes R6-65 and R6-75 have a creamy, smooth viscosity and can be stored in both tubes and small single-dose packaging. They can be easily dispensed from the tubes.

[0106] The paste was stored under various conditions (see Table 3). The properties of paste R6-65 according to the present invention remained largely unchanged. Paste R6-65 remained homogeneous and plastic over a high humidity range (10%RH to 75%RH), and therefore can be preserved without problems even in individual packaging. Even in open packaging, paste R6-65 remains creamy and smooth for extended periods.

[0107] The Proxyt RDA 7 fine product was also initially paste-like but dried relatively quickly. The remaining paste retained a crumbly, sticky consistency and was considerably difficult to handle. [Table 3]
