Definitions
- the dental bleaching agent of the present invention includes apatite, more preferably in nano-sized particle sizes, also more preferably as fluoroapatite Remineralization of the tooth surface act.
- the discoloration of teeth may be due to the natural aging process, the use of certain foods and tobacco, diseases, injuries, medicines and innate and environmental conditions. Since white or light teeth are generally more aesthetic than dark or discolored teeth, there has always been much interest in the development of teeth whitening materials and methods.
- Some dentifrices such as toothpastes, gels and powders contain active oxygen or hydrogen peroxide-releasing bleaching materials.
- Such bleaches contain peroxides, percarbonates and perborates of alkali and Alkaline earth metals or complex compounds containing hydrogen peroxide.
- percarbamide also called urea peroxohydrate or urea - hydrogen peroxide.
- Percarbamide has been used in dentistry for decades as an oral antiseptic. Urea itself is described in the literature as a keratinizing agent for the gums. Tooth whitening was an observed side effect with extended contact times.
- Other bleaching agents such as. As peroxyacetic acid and sodium perborate, are also well known in the medical, dental and cosmetic field.
- bleaching gels The bleaching gels on the market, known worldwide as “bleaching gels", are divided into three categories (Reality Report VoI .14 / 2000), namely "Power Bleaching”, “Assisted Bleaching” and “Home Bleaching". To save time and money, "dental bleaching" in the dental office is the preferred method for bleaching discolored teeth.
- Sodium monofluorophosphate, sodium fluoride and zinc fluoride, antimicrobial agents such as chlorhexidine, tetracycline, cetylpyridinium chloride, benzalkonium chloride, cetylpyridinium bromide, methyl benzoate and propyl benzoate.
- Discus Dental offers bleach with additions of amorphous calcium triphosphate. Their advantage lies in the addition which is in principle suitable for remineralization during the bleaching process. In slightly acidic conditions, where o.g. Bleaches are generally more stable, but these are not stable. They also contain no fluoride.

- heat mouth temperature, hot light, laser, or possibly other sources
- energy-absorbing substances e.g. Carotenoids, coronene, bixin, perylene, flavins etc.
- apatites provide an important basis for the incorporation of calcium into hard tooth substances (e.g., enamel, dentin, bone) and that they play an important role in healthy teeth, when combined with other phosphate and non-phosphate minerals.
- hard tooth substances e.g., enamel, dentin, bone
- the best known representative of this class of substances is the hydroxyapatite with stoichiometric formula Cai 0 (PO 4 ) 6 (OH) 2 or Ca 5 (PO 4 ) 3 0H.
- Cai 0 (PO 4 ) 6 (OH) 2 or Ca 5 (PO 4 ) 3 0H In its synthetic and biocompatible appearance, it is used in many applications in dentistry, orthopedics and maxillofacial surgery, never occurring in its pure form in biological tissues. This is a consequence of the possible isomorphic exchange of the Ca 2+ , PO 4 3 " and OH " ions, respectively.
- the Ca 2+ -IOn can be produced by a number of (mostly divalent) cations.
- the phosphate anion can be replaced by carbonate, hydrogen phosphate, pyrophosphate, sulfate, aluminate and silicate anions; on the other hand, the hydroxide ion can be replaced by halide, carbonate and oxide ions.
- hydroxyapatite is the one most used for the production of materials for orthodontics or for biometric applications.
- Particularly suitable exchange cations are: Na + , K + , Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ , Y 2+ , Ti 2+ , Zr 2+ , Mn 2+ , Fe 2+ , Pd 2+ , Cu 2+ , Ag + , Zn 2+ , Sn 2+ , Re 2+ , Re 3+ , Al 3+ In 3+ and / or Y 3+ .
- calcium can be replaced by strontium up to about 30% without altering the crystal structure.
- strontium up to about 30% without altering the crystal structure.
- the presence of this element in apatites, which are used in the dental field, is of importance against the background of a possible caries-inhibiting effect as well as a decreased dentin sensitivity. Furthermore, the solubility is lowered. Furthermore, it has been found within the scope of the invention that when certain cations are incorporated into apatites, an antimicrobial effect can be achieved. Particularly useful in this context is the incorporation of Cu 2+ , Ag 2+ , Zn 2+ , and / or Sn 2+ .
- Anions can also act as exchange ions.
- CO 3 2 " , HPO 4 2" , HCO 3 " and P 2 O 7 4" are to be mentioned as B anion, the y value is usually 0-2.
- the hydroxide ions are replaced by fluoride or chloride ions.
- the fluorapatite is characterized by an increase in crystal dimensions and a decrease in the parameters of the unit cell. Furthermore, its solubility is lower and its thermal stability greater, which is why it is used in the treatment of bone diseases or dental caries.
- the cell parameter a of the unit cell is increased or the cell parameter c is reduced in the case of chlorapatite.
- the different crystal lattice is a consequence of the different ionic radii of the fluoride or chloride.
- Fluorapatite is particularly interesting. Because of its lower solubility in the weakly acidic region, fluoridation of the tooth surfaces, ie, conversion of hydroxyapatite into fluoroapatite on the surface of the tooth, can lead to less acid attackable teeth, thus becoming more caries resistant. The presence of fluoroapatite on the tooth surface provides the opportunity for ion exchange between the hydroxylapatite of the tooth surface and the fluoroapatite during the bleaching time. The tooth surface is thus cleaned oxidatively and at the same time made more acid-resistant.
- the bleaching agent for use in a dental bleaching agent usually has a slightly acidic pH to ensure the stability of the bleaching agent such as a peroxide, the enamel is easily etched during bleaching.
- the simultaneous presence of the apatite surprisingly leads directly, ie in situ, during bleaching to a repair of the attacked enamel. Since the specific surface of nano-particles is particularly large, the remineralizing effect of nano-apatites can be orders of magnitude stronger.
- the nano-apatites preferably consisting of nanoparticles or comprising these can be prepared by the methods customarily used for the production of nanocrystalline materials, eg.
- atomic-based methods chemical or physical vapor deposition "vapor deposition", condensation in the gas phase, reactions from aerosols or
- conventional methods mechanical abrasion, crystallization from the amorphous phase, phase separation.
- the precipitation method is a conventional method of producing very fine powder or colloidal suspensions which are successful in the synthesis of clusters used in the nano area, z. B. in the SoI gel technique.
- Nanocrystalline materials are generally man-made materials characterized by continuous phases or by granular structures and usually less than 200 nm in length. Depending on the number of dimensions in which these materials have a nanostructure, a distinction is made between (i) zero-dimensional (atomic clusters, eg dispersed in a matrix of non-nanocrystalline material, filaments, tubules), (ii) one-dimensional (monomolecular layers nanodimensioned only in terms of layer thickness), (iii) two-dimensional (granular superpositions, "granular superpositions", ultra fine layers) and (iv) three-dimensional (in all three dimensions nanoscale structures) materials (RW Siegel, in Materials Science and Technology, Vol. 15: Processing of Metals and Alloys, RW Chan, 583 (1991)).
- zero-dimensional atomic clusters, eg dispersed in a matrix of non-nanocrystalline material, filaments, tubules
- one-dimensional monomolecular layers nanodimensioned only in terms of layer thickness
- the specific properties of the nanocrystalline materials result from three fundamental features, namely (i) the atomic size range of ⁇ 200 nm, (ii) the high proportion of atoms involved in the interfaces, and (iii) the interactions between the individual subregions.
- nanoapatites particularly suitable for bleaching additive addition of the invention: the interactions of crystalline nanoapatite in a bleach formulation with its biological environment can be far more intense than with conventional apatite.
- the particle size of the apatites to be used in the dental material according to the invention is not critical over the ranges indicated. In preferred embodiments, they are characterized in that the particle size of Apatitteilchen to more than 50 wt .-%, optionally more than 60 wt .-% or even more than 70 wt .-% in the range ⁇ 500 nm, more preferably more than 50 wt .-%, optionally to more than 60 wt .-% or even more than 70 wt .-% in the range ⁇ 200 nm, and most preferably to more than 50 wt .-%, optionally to more than 60 wt .-% or even more than 70 wt% in the range ⁇ 100 nm. In a preferred embodiment of the invention, the apatite particles are surface-treated to achieve better dispersivity.
- the Apatit sleepllstoffe may be surface-treated with esters of phosphoric, phosphonic or carboxylic acids.
- esters of mono-di- and triphosphonic acids such as e.g. Tris (phosphonomethyl) amine, azacycloheptane-2, 2-diphosphonic acid, hydroxyethane-1, 1-diphosphonic acid.
- treatments with phosphate salts can be beneficial.
- Another method is to apply a layer of SiO 2 or ZrO 2 on the nanometer scale and subsequent treatment with a functional silane such as hydroxy, amino, alkylorganosilanes.
- the apatites are present in the bleaching material in an amount sufficient to allow ion exchange with the biological environment. Preference is given to proportions by weight of from 1 to 20% by weight, more preferably from 2 to 10%, based on the total weight of the bleaching material.
- the bleaching material may contain additives of optional, but nevertheless very advantageous and no less preferred desensitizing agents, which also have the desensitizing and remineralizing effects in bleaches such as fluorides (sodium monofluorophosphate, sodium fluoride, calcium fluoride, etc.), nitrates (sodium nitrate, potassium nitrate, etc.), strontium compounds (eg, strontium chloride, etc.).
- fluorides sodium monofluorophosphate, sodium fluoride, calcium fluoride, etc.
- nitrates sodium nitrate, potassium nitrate, etc.
- strontium compounds eg, strontium chloride, etc.
- bioactive or antibiotic substances may be added without any limitation, e.g. Transforming Growth Factor Beta, Cell Attachment Factors, Endothelial Growth Factors, Bone Morphogenetic Proteins, Penicillin, Chlortetracycline Hydrochloride, Chloramphenicol, Oxytetracycline, etc.
- wetting agents may also be present in the tooth whitening agent according to the invention as further additives. Preference is given here to the use of sodium lauryl sulfate.
- the bleaching agents according to the invention can be used very well for whitening teeth because of their excellent remineralizing and desensitizing properties.
- the apatite portion of the tooth bleaching formulation may deliver ions to the tooth to be bleached (including fluoride, phosphate, calcium).
- the retention of nanocrystals in interstitial clefts of the enamel or dentin can provide a remineralizing effect beyond the bleaching process.
- the effect envisaged according to the invention namely whitening of the teeth with simultaneous repair of minor lesions by exchange of ions with the tooth substance and, especially when using nano-fluorapatite, the "hardening" of enamel by fluoride exchange is achieved by the tooth bleaching formulations according to the invention.
- the apatite additive of the invention can be used in typical dental bleaching formulations such as glycerol as a base material, pyrogenic silica as a thickener, percarbamide as a bleaching agent.
- Nanocrystalline fluoroapatite was crystallized from a ternary microemulsion.
- an aqueous phase containing CaCl 2 (Merk, Darmstadt, Germany) was emulsified in a mixture of Empilan KB6ZA (ethoxylated lauryl alcohol, Albright's Wilson, Meuse, France) and octane (Sigma-Aldrich, Schnelldorf, Germany) in a fixed ratio of 3: 7 ,
- the microemulsion was stirred at 30 0 C with 30 (I), 36.36 (II) and 50 (III) wt.% 1.0 mol CaCl 2 vigorously, to obtain a micro emulsion.
- the SEM-EDX data (Energy Dispersive X-ray spectrometry) of the powder show sufficiently good agreement with calcium fluorapatite, cf. also figures.
- nanoapatite powder from Example 1 (I) 100 g is slurried in acetone and mixed with 6 g of hydroxyethyl phosphoric ester with constant stirring. After stirring for 2 h, centrifuging off and washing three times with acetone, it was dried.
- One-component gels The basic material used was glycerol and the thickener fumed silica.
- the bleaching formulations prepared were used for whitening enamel and dentin.
- the basic material used was glycerol and the thickener fumed silica.
