  1. ORAL CARE

  2. ORAL CARE PRODUCTS • Dentifrice • Oral Rinses

  3. ORAL ENVIRONMENT Teeth Gingiva / Mucosa Saliva Plaque Tartar Caries Periodontal Disease

  4. ORAL ENVIRONMENTCARIES A progressively destructive, infectious disease resulting in: • Demineralization of enamel / cementum • Bacterial penetration to pulp • Formation of macroscopic activity Caries promotion Caries reduction dietary carbohydrate increased salivary flow reduced salivary flow reduced plaque cariogenic bacteria fluoride Sound enamel plaque acid prod saliva acid neutralization mineral loss mineral gain (fluoride) Lesions Cavity

  5. COMPOSITION OF DENTIFRICES

  6. COMPOSITION & CHEMISTRY OF DENTIFRICES DENTIFRICE: A dentifrice is a substance used with a toothbrush for the purpose of cleaning the accessible surfaces of the teeth (American Dental Association) TOOTHPASTE: Toothpaste is a colloidal suspension of a mixture of ingredients that must be carefully balanced in order to provide an efficacious, safe, and consumer friendly product

  7. TOOTHPASTE CONSIDERATIONS • Safety and Efficacy • Controlled foaming • Abrasiveness • Consistency • Consumer Friendly • Pleasing taste • Ease of use • Pleasing appearance

  8. PRODUCT CRITERIA • Minimum one year shelf life • Easily dispensable • Compatible with the package • Efficacious • Safe

  9. TOOTHPASTE INGREDIENTS • Abrasive • Binder • Humectant • Sweetener • Flavor • Surfactant • Active Ingredients

  10. ABRASIVE / POLISHING AGENTS • Function: • Cleaning and polishing by providing friction.( 20-50%) • Characteristics: • Solid, insoluble particles • Abrasive • Potential for fluoride interaction in case of calcium salts

  11. ABRASIVE • Types : • Silica ( organic softer version ) • Phosphate Salts – ie “Dical” • Carbonates – ie Calcium Carbonate or Chalk ( mineral type capable of eroding the enamel surface) • Others

  12. Chalk or precipitated calcium carbonate • Double decomposition of calcium chloride and sodium carbonate Dicalcium phosphate • Low in abrasion , incompatible with most flourides, should contain a stabilizer to prevent grittiness or caking on ageing hence can be replaced with magnesium phosphate.

  13. SILICAS • Two types • Abrasive silica • Thickening silica • Abrasives are dense, relatively non absorbant, odourless and tasteless • Known as xerogels free of voids or air spaces • Minimal effect on the consistency of finished paste

  14. Thickening silica ( aero gels) • Small sized particles with very large surface areas • Capable of swelling and thickening the paste. • In combination with abrasive silica form the basis of clear gel pastes and become transparent when mixed with liquid ingredients • Non reactive and compatible with flourides

  15. BINDER • Function: Used to stabilize toothpaste formulations to prevent separation of the liquid and solid phases • Characteristics: Can be natural or synthetic

  16. BINDER (0.9- 2 %) • Types: • Natural Polymers • Carboxymethyl Cellulose (CMC) • Carrageenans • Xanthan Gum • Synthetic Polymers • Others

  17. HUMECTANT • Function: Used in toothpaste to prevent loss of water and subsequent hardening of the product upon exposure to air • Characteristics: 1. Affect taste perception 2. 80% level produce a clear translucent toothpaste 3. 20-40% produces opaque toothpastes

  18. HUMECTANT • Types: • Glycerine • Sorbitol( 70%) less exp than glycerin • Polyethylene Glycol • Xylitol • Propylene Glycol (viscosity and bitterness limits its utility )

  19. SWEETENER • Types: • Sodium Saccharin • Sodium Cyclamate • Acesulfame K

  20. SWEETENER • Function: An important part of toothpaste flavoring system • Characteristics: Government regulations Non-cariogenic

  21. FLAVOR • Function: Improve taste of toothpaste • Characteristics: One of the most important factors for consumer A mixture of flavoring agents

  22. FLAVOR • Types: • Minty • Fruity • Medicinal • Cinnamon

  23. Oral products have a unique and specialized flavor requirements. To be successful in oral products, a flavor must: • Have a pleasant taste while brushing • Leave a pleasant taste in your mouth after brushing • Be compatible with the base

  24. All factors being roughly equal – “mouthfeel” appearance, perceived therapeutic attributes, etc. – the consumer will look to flavor as the determinant in selecting a product for use day after day and year after year.

  25. SURFACTANT • Function: 1.Produce foam and aid in the removal of debris 2.Emulsifies flavoring agents 3. reduces surface tension between dentrifices and mouth plague and increases penetration between cavities and gums. • Characteristics: May react with other toothpaste components High level may cause mucosal irritation

  26. SURFACTANT ( 0.5-2%) • Types: • Sodium Lauryl Sulfate • Sodium N-Lauroyl Sarcosinate • Sodium Dodecyl Benzene Sulfonate • PEG Oil

  27. FLUORIDE ACTIVES • Function: Increase resistance to enamel solubility • Characteristics: Regulated by Government Restricted usage level Soluble fluoride ion is essential for activity

  28. FLUORIDE ACTIVES • Types: • Sodium Fluoride NaF • Sodium Monofluorophosphate MFP • Stannous Fluoride SnF2

  29. Anticaries Dentifrices: FDA Tentative Final Monograph

  30. OTHER ACTIVES • Tartar Polyphosphates Zinc Citrate • Plaque / Gingivitis Triclosan SnF2 Chlorhexidine Zinc Citrate • Desensitizer Potassium Nitrate • Whitening Calcium Peroxide Hydrogen Peroxide
