Definitions
- the technical field of the invention is that of hygiene products and oral cosmetics.
- the present invention relates to a novel enzyme complex capable of preventing the formation of dental plaque, caries and tartar, while achieving natural whitening of the enamel.
- the present invention also relates to a novel form of prevention and treatment of dental bacterial biofilm by said enzyme complex.
- the sugar provided by food is broken down into glucans by cariogenic bacteria in the oral cavity, which form a bacterial biofilm on tooth enamel.
- a bacterial biofilm is an organized and structured community of bacterial cells entangled in an extracellular matrix of variable density and composition.
- the majority of dental biofilm matrix is made up of polysaccharides. In fact, up to 40% of the dry weight of dental biofilm is composed of polysaccharides.
- this bacterial biofilm grows in thickness on the teeth, first forming soft dental plaque, composed of soluble glucans (known as (1 - 6)-a-D-glucan or dextrans), then plaque. hard dental formed by the transformation of said dextrans into water-insoluble glucans (known as (1 -3)-a-D-glucan or mutanes).
- Streptococcus mutans is the main cause of the formation of bacterial biofilm, the main cause of cavities, because it uses dietary sucrose to produce lactic acid and synthesize extracellular polysaccharides. in particular (1 -3) and (1 -6)-aD-glucans, which promote the formation of biofilms and increase the resistance of microorganisms in the biofilm. Lactic acid demineralizes the tooth surface, which promotes the formation of dental plaque and periodontitis.
- the acidic biofilm formed by Streptococcus mutans is very resistant to the hostile environment, host immunity and antimicrobial treatments, notably lysozyme. The latest research on dental pathology shows the difficulty of eliminating these streptococci protected within the matrix by the bacterial biofilm. [0010] There is therefore a need to prevent the proliferation of Streptococcus mutans.
- Lactoperoxidase is an enzyme that is known for its bactericidal effect in the presence of hydrogen peroxide and thiocyanate, in particular against Streptococcus mutans. It is known to provide these three substances by providing exogenous lactoperoxidase, glucose oxidase and potassium thiocyanate. In this type of composition, however, the formation of hydrogen peroxide is insufficient for the bactericidal effect of the lactoperoxidase to significantly affect the Streptococcus mutans biofilm from the point of view of reducing the formation of caries and/or tartar. Furthermore, the provision of exogenous glucose in this type of composition is not recommended in the field of oral hygiene. This solution is therefore not satisfactory for preventing the proliferation of Streptococcus mutans.
- the invention offers a solution to the problems mentioned above, by providing an enzymatic complex whose composition, which is based in particular on a synergistic action of its different constituents, results from numerous studies carried out by the applicant. Of natural origin, this enzymatic complex is respectful of the overall health of the consumer and has no side effects.

- the enzymatic complex further comprises lysozyme.
- Another aspect of the invention relates to an oral composition for use in the treatment of dental plaque and the bacterial biofilm of plaque and the natural whitening of tooth enamel, which comprises an enzyme complex as described above. .
- the oral composition comprises from 1.4 to 3%, preferably from 2.0 to 2.5%, of enzymatic complex.
- the oral composition further comprises lactoferrin.
- the oral composition further comprises: from 20 to 60%, preferably from 30 to 50%, of sorbitol, from 1 to 20%, preferably from 5 to 10%, of xylitol , from 0 to 3%, preferably from 1 to 2%, of polysorbate 80, from 0 to 3%, preferably from 1 to 2%, of polysorbate 20, from 0 to 0.5%, preferably from 0.1 to 0 .2%, sodium saccharinate, 0 to 5%, preferably 1 to 2%, colloidal silica, 0 to 3%, preferably 1 to 2%, dimethicone, 0 to 5%, preferably 1 to 2%, mint flavor and/or mint essential oils, 0.1 to 0.5%, preferably 0.1 to 0.3%, zinc citrate, 0 to 0 .5%, preferably 0.1 to 0.2%, potassium thiocyanate, 0 to 0.5%, preferably 0.1 to 0.2%, preservative, and water, according to a sufficient quantity to reach
- the oral composition is in the form of paste, liquid, gel, mouthwash, nebulosity, spray, capsule, tablet or chewing gum.
- the glycolytic enzymatic system of the invention makes it possible to significantly reduce the toxicity of Streptococcus mutans.
- This enzymatic complex acts on dietary sucrose so as to deprive the bacteria of their substrate but also by directly degrading the cell wall of these streptococci.
- the enzyme complex according to the invention advantageously reduces the quantity of sucrose available in the oral cavity by transforming it into ose monomers (glucose) and fructose, which deprives cariogenic bacteria of metabolic substrate, greatly reduces the production of soluble and insoluble glucans, and thus contributes to the reduction of bacterial biofilm.
- the complex enzymatic according to the invention advantageously prevents the formation of bacterial biofilm and disassembles existing biofilms.
- the destruction of the bacterial biofilm also reduces the formation of dental plaque, which is smelly and yellows the teeth under the effect of tobacco or dyes such as coffee or tea.
- Soluble glucans are transformed into saccharide dimers or trimers by the mixture of glucanohydrolase enzymes, these saccharide derivatives then being transformed into ose monomers by the action of the glycoside hydrolase enzyme, preferably amyloglucosidase, for example amylo-a-1,6 glucosidase, which hydrolyzes the (1 -6)-a-D saccharide bonds of ose dimers and trimers.
- the glycoside hydrolase enzyme preferably amyloglucosidase, for example amylo-a-1,6 glucosidase, which hydrolyzes the (1 -6)-a-D saccharide bonds of ose dimers and trimers.
- the residual saccharide derivatives coming from the degradation of the glucans of dental plaque are then transformed into ose monomers by a glycoside hydrolase enzyme hydrolyzing the saccharide (1 -6)-aD, while the ose monomers are transformed by the enzyme oxidoreductase to D-glucono-delta-lactone, but also especially to hydrogen peroxide.
- the oxidoreductase enzyme forms hydrogen peroxide from ose monomers.
- the formation of hydrogen peroxide is advantageous because it has an antiseptic effect actively participating in eliminating Streptococcus mutans, and a natural whitening effect on the enamel, which contributes to a more beautiful appearance of the teeth.
- the enzymatic complex according to the invention provides several sources of hydrogen peroxide in the oral cavity, by the in situ transformation of sucrose, saccharide dimers and trimers, and soluble glucans. and glucans insoluble in ose monomers, that is to say in glucose.
- the glucose thus available on a regular basis, allows, through its transformation by the enzyme gluco-oxidase, to produce hydrogen peroxide directly in contact with the teeth in a regular, gentle and lasting manner, for an optimal effect with regard to oral hygiene and enamel whitening.
- the quantity of glucose present in the oral cavity at any time advantageously remains much lower and therefore much less harmful than when exogenous glucose is supplied.
- the hydrogen peroxide generated in situ thanks to the enzymatic complex according to the invention is produced in a much lower quantity than that usually used for teeth whitening which is supplied exogenously, but it is also present in the oral cavity for a longer period, which makes it possible to provide a satisfactory progressive whitening effect, without being accompanied by the usual effects encountered with a massive and exogenous supply of hydrogen peroxide, namely: demineralization of the hard tissues of the tooth , irritation of the mucous membranes, reaction with filling materials, premature wear of the enamel with hypersensitivity and weakening of the teeth.
- the peroxidase enzyme advantageously transforms the thiocyanate naturally present in saliva into hypothiocyanate, which is a powerful bactericide and further reinforces the action of the enzymatic complex of the invention with regard to dental health. To reinforce this effect, it is also possible to add exogenous thiocyanate.
- a saccharase preferably an invertase or an isomaltase
- this enzyme breaks down the starch and glycogen possibly present in the oral cavity into dimers of oses (maltose) which are then transformed into ose monomers by an alpha amylase naturally present in saliva.
- lysozyme to the enzymatic complex according to the invention is advantageous in that it hydrolyzes the polysaccharide cell wall of bacteria and, in the absence of the bacterial biofilm generated by Streptococcus mutans, presents a strong bactericidal activity actively participating in the 'oral hygiene. Indeed, the bactericidal activity of the enzymatic complex according to the invention is reinforced by lysozyme which acts more effectively “after” the disappearance of the bacterial biofilm.
- the enzymatic complex according to the invention ensures the following beneficial effects while being respectful of the overall health of the consumer and without side effects: an anti-cariogenic sugar action in inhibiting the acidic transformation of dietary sugars and therefore a preventive effect against cavities, an action of destructuring the bacterial biofilm of dental plaque and therefore a preventive effect against periodontal diseases and tartar, an action of cleaning up the microbiota of the cavity oral by reduction of pathogenic bacteria under the effect of stimulation of the salivary lactoperoxidase system, a gentle and prolonged action of whitening of dental enamel by natural production of hydrogen peroxide.
- lactoferrin to an oral composition comprising an enzyme complex, by ensuring the chelation of iron necessary for the binding of the polysaccharides of the microbial envelope, necessary for the survival of cariogenic streptococci, advantageously leads to better eradication of the Streptococcus mutans biofilm and participates in the synergy mentioned above. Indeed, lactoferrin lyses the bacterial membrane of many organisms, including acidogenic streptococci, and thus significantly increases the body's immune defenses.
- Streptococcus mutans uses dietary sucrose to synthesize extracellular polysaccharides (EPS) in order to promote the formation of bacterial biofilms.
- EPS extracellular polysaccharides
- a-(1-6) (dextran)-linked glucose polymer with a-(1-3) (mutane) branch linkages plays a crucial role in regulating of the formation and virulence of the cariogenic biofilm by influencing the physical and biochemical properties of the biofilm.
- Cariogenic biofilm can promote the accumulation and adhesion of microorganisms and accelerate the coherence of bacterial cells with each other and with the apatite surface, thereby modulating the initial stages of cariogenic biofilm development and proliferation and facilitating the formation of dental plaque. mature.
- the EPS matrix protects microorganisms from hostile influences, affects the diffusion of substances into and out of the biofilm, and helps concentrate metal ions and other physiological nutrients in a microenvironment.
- the cariogenic biofilm hinders the diffusion of host-induced antibiotics and antimicrobial factors into the deeper layers of the biofilm, thereby increasing the resistance of microorganisms in the biofilm.
- DexA dextranase hydrolyzes the a-1,6 bonds of dextran and produces isomaltoligosaccharides of different sizes.
- Dextranase DexA is crucial in the bacterial biofilm formation process and considered responsible for the pathogenic plaque ecosystem: DexA dextranase hydrolyzes glucans as potential storage polysaccharides to provide nutrients for bacteria metabolism and controlling the quantity and content of extracellular glucans to make it more adhesive.
- the effect of the dextranase DexA can be competed by an external dextranase enzyme.
- the saccharide derivatives thus obtained give ose monomers which, under the action of oxidoreductase enzymes, produce hydrogen peroxide which triggers the highly bactericidal salivary lactoperoxidase reaction and results in the disappearance of the bacterial biofilm.
