Title: Dental Caries


1
Dental Caries
  • By Mary Kay and Emily Cooper

2
What is Dental Caries
  • Another word for tooth decay
  • Formed from the accumulation of
  • dental plaque

3
What Causes Dental Caries?
  • Bacteria in the mouth
  • Most importantly- Streptococcus mutans
  • Break it down

4
How It Is Formed?
  • Similar to a biofilm- build up of bacteria
  • Bacteria creates lactic acid from sucrose and
    carbohydrates
  • S. mutans attaches to the tooth (proteins coated
    on tooth)
  • Lactic acid breaks down enamel for plaque

6
Where?
  • The mouth and teeth
  • Especially crevices and places where there is a
    less chance of being destroyed

7
Protection?
  • Saliva contains lysozyme
  • Protects exposed surfaces
  • Crevicular fluid- a tissue that flushes out
    gingival crevice
  • Contains phagocytic cells and immunoglobulin

8
Prevention
  • Lower sugar intake
  • Brush and floss your teeth
  • Professional cleaning
  • Fluoride
  • Chlorhexidine (most effective mouth wash)

Process
