Definitions
- Polyphosphonate derivatives for toothpaste compositions are Polyphosphonate derivatives for toothpaste compositions.
- the invention relates to a polyphosphonate compound used as a medicament, in particular for oral hygiene, an oral hygiene composition comprising such a bisphophonate compound, the use of such a compound for the preparation of a medicament more specifically intended for the prevention of the appearance and development of dental plaque.
- the oral bacterial flora is made up of very many taxa in association, and organized in the form of a multigeneric biofilm commonly called dental plaque. This flora is associated with the development of carious and periodontal pathology. Certain species such as Streptococcus mutans, S. sobrinus and Lactobacillus, identifiable in this biofilm, are cariogenic and constitute the primary colonizing species of dental surfaces by interaction with molecules of salivary origin.
- the bacterial species of the oral flora express virulence factors the effects of which are observable locally and certain from a distance: colonization factors (adhesins), persistence (aggressors, stress proteins ...), and tissue destruction (aggins, protease activities ).
- Streptococci in the oral cavity colonize tooth surfaces via adhesins, which are protein components of the bacterial wall.
- S. mutans plays a key role both in the initiation and the development of the carious process thanks to its homofermentative metabolism, but also to its capacity to produce homopolymers of glucose in particular (soluble dextrans), synthesized by glucosyltransferases (GTFs).
- GTFs participate in the adhesion capacities of cariogenic streptococci via glucose polymers.
- Decay can affect the enamel, dentin and pulp of the tooth. Symptoms can range from simple demineralization to complete destruction of the tooth.
- Dental plaque adheres to the very thin layer that surrounds each tooth and that includes salivary proteins.
- a 5-day plaque if not brushed off, can form a thick layer up to about 60 micrometers.
- a cariogenic plaque can often include 2x10 8 S. mutans bacteria / mg of dry weight and can quickly releasing enough glucose and fructose by fermentation to generate an acidic plaque pH of 5.5 or less causing demineralization of dental surfaces.
- chlorhexidine Certain substances have been identified as inhibiting the formation of dental plaque, such as chlorhexidine, when it is used twice a day in oral rinse at a concentration of 0.2%. Its prolonged persistence in the oral cavity makes it more effective. Chlorhexidine also has an affinity for hydroxyapatite (mineral component of enamel), but due to its side effects (staining of teeth, mucosa and composites), chlorhexidine is not suitable for long-term treatment .
- Chlorhexidine in oral rinse remains one of the most recommended antiseptics in the prevention of dental plaque, being indicated when the mechanical methods must be suspended or temporarily reinforced.
- Another non-ionic anti-bacterial agent, triclosan, mentioned for example in US Pat. No. 6,136,298, combined with a copolymer of polyvinyl methyl ether and maleic acid has the advantage of reducing plaque, gingivites, tartar and cavities, without side effects and without modifying the ecology of the oral flora.
- Another approach is to act on the specific interactions that exist between microorganisms in the oral cavity and dental surfaces. Specific compounds can interfere with these interactions and constitute a means of preventing or controlling the formation of dental plaque.
- Surfactants or polymers have thus been used intended to reduce or prevent salivary proteins from being adsorbed on the surface of the enamel. Surfactants naturally tend to adsorb on all surfaces, greatly reducing interfacial energy. The affinity of the molecule for an interface is generally affected by the properties of the hydrophobic and hydrophilic parts. Most surfactants adsorb on the surface in well-defined directions, and the action on protein adsorption and desorption can be closely associated with the orientation of the surfactants on the surface.
- a dental composition comprises between 0.01 and 20% by weight of a surfactant, or of a mixture of surfactants, anionic, cationic, nonionic, and zwitterionic.
- surfactants having an oral tolerance such as monoglycerides, glycerides, monoglycerides sulfonates, other fatty acid esters, alkyl sulfates, polysorbates, alkyl quaternary ammonium compounds, carboxylates, polyoxyethylenes, phosphonates, sodium alkyl sulfates, sodium lauryl sulfates.
