Transcript The Connection between Anaerobic Metabolism and Dental Plaque

What is the Connection between
Anaerobic Metabolism and
Dental Plaque?
By,

Dental Plaque
• Bacteria
• Polysaccharides form sticky colonies
• Plaque formation
• Anaerobic metabolism
CAUTION!
-High Sugar Diets
-Carbohydrates: Sugars, Starches
-Examples: Candy, Fruit, Cake, Soft Drinks, Ice Cream
How it works…
Carbohydrates (Sugars and Starches)
Bacteria present in mouth utilize sugars ex: Sucrose
Acids (waste products) ex: Lactate & Pyruvate
Over time…
Overtime acid destroys tooth enamel, even dentin
rapid bacterial growth in holes made
Causes
Tooth Decay and/or Gingivitis
long term
Plaque on tooth roots, under gum, can cause breakdown of
bone and tooth support (Periodontal Disease)
Bacteria uses fructose to get energy
Lactic acid creates extra acidity to decrease the pH, which can dissolve the calcium
phosphate in the tooth enamel leading to the start of a cavity.

Sugar, Saliva, and Bacteria lead to tooth decay over time.
