Definitions

  • the invention relates to the use of a composition containing at least one sparingly water-soluble calcium salt and / or its composite material for the protection and / or the therapeutic and / or preventive treatment of teeth and / or bones in the case of damage caused by external influences, in particular body-related , chemical, physical and / or microbiological nature, in particular for the prevention and repair of erosions on bones and teeth, especially enamel, care of the enamel, and to protect the teeth from attack by acids, in particular by bacterial activity or by the action of acids from foodstuffs, for protection against demineralization of the teeth, for sealing fissures, for protection and / or repair of primary lesions and / or priming in the enamel, and for smoothing the tooth surface, for caries prevention for improving the cleanability, the mechanical n Resistance of teeth and dental health in general
  • Phosphate salts of calcium have long been added to the formulations of dentifrices and dentifrices both as abrasive components and to promote enamel remineralization. This is especially true for hydroxyapatite and fluorapatite, as well as for amorphous calcium phosphates and for brushite (dicalcium phosphate dihydrate). Calcium fluoride is also included in dentifrices and has been described several times as a component for strengthening enamel and preventing tooth decay
  • the enamel and the supporting tissue of the bones consist predominantly of the mineral hydroxylapatite.
  • hydroxylapatite deposits in an orderly fashion on the protein matrix in the bone or tooth, which consists mainly of collagen.
  • the formation of the hard and resilient mineral structures is controlled by the so-called matrix proteins which, in addition to collagen, are formed by further proteins that attach to the collagen and thus effect a structured process of annealing, also referred to as biommeralization
  • the Enamel which lies above the dentin and covers the tooth crown in varying degrees, is particularly hard and the most important protective shield of the tooth.
  • the humid oral cavity it is in a constant de-and Reminerahstechniksreteric with the Saliva rich in minerals. Under ideal conditions it is able to compensate mineral losses in the tooth material
  • acids in the oral cavity eg by the consumption of acidic or acidic foods, such as fruit juices, lemonades, yoghurt, salad dressing, fruit or even wem, soften and finally dissolve the enamel
  • acidic or acidic foods such as fruit juices, lemonades, yoghurt, salad dressing, fruit or even wem, soften and finally dissolve the enamel
  • Acids absorbed through food are also referred to as extinct
  • the damage to the enamel also favors the colonization of the tooth with bacteria, which in turn can produce more acids through metabolic processes in the immediate vicinity of the enamel and thus ultimately lead to tooth decay
  • bone substitute materials which can be administered in liquid form.
  • a particularly small particle size is required that can not be achieved satisfactorily in the conventional bone substitutes.
  • the previously available liquid administered bone substitute materials have shown coarse-crystalline inorganic components and the lack of bioanalogous organic components at best a biocompatible, possibly resorbable effect on Desired are, however, the natural Biominerahsation and thus the bone growth directly demanding, osteomductive, osteoconductive or osteostimulant materials
  • Composite materials of the type described are accessible by a synthetic route, as described, for example, by B Flautre et al., J Mater Sei Mater In Mediane 7 (1996), 63. In these composites, however, the grain size of the calcium salts is above 1000 nm, which is too high to achieve a satisfactory biological effect as Remineraltechnischsstoff
  • RZ Wang et al J Mater. Lett. 14 (1995) 490 describes a process for producing a hydroxyapatite-collagen composite material in which hydroxyapatite having a particle size in the range of 2 to 10 nm is deposited on the collagen matrix in a uniformly distributed form
  • Composite mat alal should have better biological effectiveness than other hydroxyapatite-collagen composites known in the art because of the femto-particle nature of the hydroxyapatite.
  • WO 01/01930 discloses composite materials which are composed of nanoparticulate sparingly soluble calcium salts and protein component and which have a remineralizing action on enamel and dentin
  • protem-containing composite materials known from the prior art is their often complicated production.
  • insoluble collagen must be handled and distributed in very large amounts of solvent, which is technically complicated
  • this process raises problems with the disposal of the wastewater produced during production

  • the mentioned external influences are to be understood as attacks by acids
  • acids is to be understood here as meaning both the intrinsic acids and the extinic acids
  • the damage by intrinsic acids relates in particular to medical conditions associated with contact of gastric acid with the oral region, in particular in regurgitation, regurgitation, heartburn or by vomiting, also in connection with pathological eating disorders, in particular bulimia
  • the use according to the invention is therefore also therapeutically applicable in the repair of damage, in particular of erosions, on bones and teeth, in particular on the enamel
  • a toothpaste used according to the invention after acid damage (etching) of the enamel after a single treatment with the composition according to the invention resulted in a very large, almost complete restoration of the enamel surface.
  • the compositions to be used according to the invention are therefore particularly suitable for the prevention and repair of erosions
  • the sparingly water-soluble calcium salts and / or their composite materials to be used according to the invention are capable of growing on the tooth, in particular on the enamel, a layer which seals off the enamel from the oral environment
  • the resulting layer is intrinsically structured and intimately bonded to the natural enamel (see Figure 4a + b) and is particularly suitable as a "sacrificial layer", which is attacked and possibly eroded when the acid attacks the teeth instead of the enamel Enamel is protected very well
  • said protection and / or said preventive treatment results in a reduction or inhibition of the demineralization of the teeth
  • said protection and / or said preventative treatment results in a sealing of fissures
  • fissures ie, the column-shaped recoveries located on the occlusal surfaces of the molars and molars
  • their susceptibility to kisses can be reduced
  • the said protection and / or said preventive treatment leads to the protection and / or repair of primary lesions and / or initial ducts in the enamel
  • said protection and / or said preventive treatment results in smoothing of the tooth surface
  • the use according to the invention makes it possible, in particular, for a layer to grow on the endogenous tooth material, which has a particularly smooth surface. This leads to a more glossy surface, which is easier to clean and less susceptible to colonization by microorganisms. In addition, the smoothing of the surface results in an improved aesthetic impression produced, which makes the teeth appear whiter or lighter
  • said protection and / or preventive treatment results in improving the cleanability of the teeth
  • said protection and / or said preventive and / or therapeutic treatment for improving dental health generally results
  • said protection and / or said preventative treatment leads to better mechanical resistance, in particular that the extent of micro-scratches, craters or mechanical abrasion is reduced
  • the use according to the invention leads to a better resistance to mechanical stress of the teeth, which, in addition to chewing, can also be caused, in particular, by vigorous brushing of teeth. Damage or removal of softened enamel can thus be avoided
