Q

WHAT IS CHEMICAL THEORY

A

Robertson 1834 - Dental caries was caused by chemical disintegration of the teeth.
- It was believed that putrefaction of protein led to formation of ammonia which was subsequently oxidized to nitric acid

Q

WHAT IS HUMORAL THEORY?

A
  • 4 Elemental Fluid (Body-blood, Phlegm, Black Bile, and Yellow bile)
  • Imbalanced of the 4 humors determine the person’s physical and mental constituent

Q

WHAT IS VITAL THEORY?

A
  • Proposed by Hippocrates, Celsus, Galen, and Auicenna

- Postulated that tooth decay originated like bone gangrene from within the tooth itself.

Q

WHAT IS CHEMICO-PARASITIC THEORY?

A
  • Said that caries is caused by acid produce by oral bacteria following fermentation of sugar.
  • Consist of 2 stages:
    Decalcification of enamel, destruction of dentin (Preliminary Stage)
    Dissolution of the softened residue of enamel and dentin (Subsequent stage)

Q

WHAT IS PROTEOLYTIC THEORY?

A

Heider and Bodecker - said that organic portion of the tooth serves as pathways for advancing. Microorganisms causing demineralization of the teeth and therefore dental caries.

  • Gottlieb
  • Pincus
17
Q

WHAT IS PROTEOLYSIS?

A
  • SCHATZ 1955
  • dental caries is a bacterial destruction of organic components of enamel and the breakdown products of this components have chelating properties dissolving the minerals in enamel.
  • This simultaneous microbial degradation of organic component by proteolysis and dissolution of inorganic part by chelation.
18
Q

Plaque - Susceptible Host - Fermentable Carbohydrates - Acid Production - Demineralization

A

W.D MILLER (CHEMICO-PARASITIC THEORY)

19
Q
  • Tooth bore a whole through your teeth
  • Hid beneath the surface
  • Drank Blood of teeth
  • Fed on the roots of jaws
A

WORM THEORY

20
Q
  • Bone like Gangrene
A

VITAL THEORY

21
Q

Name of the disease

A

DENTAL CARIES

22
Q

Consists of 2 stages:

  • Decalcification of enamel, destruction of dentin (Preliminary Stage)
  • Dissolution of the softened residue of enamel and dentin (Subsequent Stage)
A

CHEMICO-PARASITIC THEORY (MILLER 1890)

23
Q
  • Body-Blood, Phlegm, Black Bile, and Yellow Bile
A

HUMORAL THEORY

24
Q

First one to recognized the organic matrix enamel

A

Ficinus

Q

First one to recognized the organic matrix enamel

A

Ficinus

25
Q

Caries is caused by acids produce by oral bacteria following the fermentation of sugar

A

CHEMICO-PARASITIC THEORY

26
Q

Organic portion of the tooth serves as pathways for advancing

A

PROTEOLYTIC THEORY

27
Q

Suggest that initial lesion of the carious process is due to the proteolytic enzymes attacking the lamallae, rod sheaths, tufts, and walls of tubules.

A

GOTTLIEB in 1944 (PROTEOLYTIC THEORY)

28
Q

Proposed that the first step in the carious process is the breakdown of dental cuticle

A

PINCUS in 1949 (PROTEOLYTIC THEORY)

29
Q

WHAT IS PROTEOLYSIS-CHELATION THEORY?

A

Dental caries destruction of organic components of enamel and the breakdown products of the components have chelating properties dissolving the minerals in enamel.
