  • Slide 5
  • 5 ORAL ENVIRONMENT TEETH Enamel hard, white outer covering surrounding the crown of the tooth. Consists of inorganic substances, calcium and phosphate. Cementum thin, bone-like material covering the root. Also consists of inorganic substances. Dentin a yellow bone-line material under the enamel Provides support Forms bulk of tooth Composed of collagen (20%) and calcium phosphate (75%) Pulp soft tissue in the center of the crown and root Contains nerves, blood vessels and lymph vessels Produces dentin Provides nourishment for tooth Functions as a sensory signal of injury Pellicle thin salivary film covering the tooth composed of proteins and lipids

  • Slide 13
  • 13 ORAL ENVIRONMENT GINGIVA / MUCOSA Gingiva dense fibrous tissue surrounding necks of teeth Covered by a smooth mucous membrane which bleeds easily when penetrated Also called periodontal tissue or gums Oral mucosa mucous membrane lining the mouth Peridontium - attachment apparatus consisting of Gingiva Cementum Periodontal ligament Jawbone Oral mucosa
  • Slide 14
  • 14 ORAL ENVIRONMENT SALIVA A complex fluid secreted by salivary glands containing water, mucin, proteins, salts and enzymes. Functions: aids in digestion lubricates both hard and soft tissues buffers cariogenic acids forms the pellicle provides minerals for repairing enamel / cementum (remineralization) delivers antimicrobial agents (immunoglobulins, enzymes, etc.)
  • Slide 15
  • 15 ORAL ENVIRONMENT PLAQUE Soft sticky, invisible film constantly forming in your mouth. Covers teeth and gums. Oral mucosa cells Saliva Bacteria Can be removed by brushing and flossing. Gram + cocci Gram + rods Gram anaerobes (healthy mouth) (gingivitis) Formation / progression influenced by: Diet Host immune system Oral environment
  • Slide 16
  • 16 Inhibition of Plaque Accumulation
  • Slide 17
  • 17 ORAL ENVIRONMENT TARTAR Calcification (crystallization of minerals) on the surface of the tooth formed mainly in the presence of plaque. Rough surface promotes further growth of plaque Stains easily (yellow / brown) Most prevalent near salivary glands and around necks and roots of teeth Removed only by dentist Tartar Control Agents (Pyrophosphate) Acts as crystal poisons to stop formation Easily degraded by oral enzymes / stabilized by fluoride and Gantrez.
  • Slide 18
  • 18 ORAL ENVIRONMENT CARIES A progressively destructive, infectious disease resulting in: Demineralization of enamel / cementum Bacterial penetration to pulp Formation of macroscopic activity Caries promotionCaries reduction dietary carbohydrateincreased salivary flow reduced salivary flowreduced plaque cariogenic bacteriafluoride Sound enamel plaque acid prod mineral loss saliva acid neutralization mineral gain (fluoride) Lesions Cavity

  • COMPOSITION & CHEMISTRY OF DENTIFRICES
  • Slide 20
  • 20 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
  • Slide 21
  • 21 TOOTHPASTE INGREDIENTS Abrasive Binder Humectant Sweetener Flavor Surfactant Active Ingredients
  • Slide 22
  • 22 ABRASIVE Function: Cleaning and polishing Characteristics: Solid, insoluble particles Abrasive Potential for fluoride interaction
  • Slide 23
  • 23 ABRASIVE Types : Silica Phosphate Salts ie Dical Carbonates ie Calcium Carbonate or Chalk Others
  • Slide 24
  • 24 Radioactive Dentin Abrasion Method This procedure involves the use of accelerated toothbrushing apparatus and dentin section that contain radioactive phosphorous. The ADA standard was set at 100, which corresponds to RDA value of 475.

  • Slide 27
  • 27 BINDER Function: Used to stabilize toothpaste formulations to prevent separation of the liquid and solid phases Characteristics: Can be natural or synthetic
  • Slide 28
  • 28 BINDER Types: Natural Polymers Carboxymethyl Cellulose (CMC) Carrageenans Xanthan Gum Synthetic Polymers Others
  • Slide 29
  • 29 HUMECTANT Function: Used in toothpaste to prevent loss of water and subsequent hardening of the product upon exposure to air Characteristics: Affect taste perception Proper usage level produce a clear translucent toothpaste
  • Slide 30
  • 30 HUMECTANT Types: Glycerine Sorbitol Polyethylene Glycol Xylitol Propylene Glycol
  • Slide 31
  • 31 SWEETENER Types: Sodium Saccharin Sodium Cyclamate Acesulfame K
  • Slide 32
  • 32 SWEETENER Function: An important part of toothpaste flavoring system Characteristics: Government regulations Non-cariogenic
  • Slide 33
  • 33 FLAVOR Function: Improve taste of toothpaste Characteristics: One of the most important factors for consumer A mixture of flavoring agents
  • Slide 34
  • 34 FLAVOR Types: Minty Fruity Medicinal Cinnamon
  • Slide 35
  • 35 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
  • Slide 36
  • 36 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.
