Q

Dental caries - Acidogenic theory of dental caries? What happens? What’s affected?

A

What happens:
- result from a metabolic shift accompanied by gradual change in ecology of the dental biofilm
- imbalance in equilibrium between tooth mineral and biofilm fluid develops
- acid produced by oral bacteria from carb fermentation
What’s affected:
- decalcification of hard tissue substance and disintegration of the organic matrix

Q

Plaque - action of bacteria?

A

Action of bacteria:

  • store glucose as glycogen (intracellular store)
  • S.mutans synthesise other polymers given access to sucrose
  • can synthesise extracellular polymers from simpler sugars
  • increase plaque bulk and are more cariogenic
  • glucosyltransferase break down sucrose into fructose and glucose, using this energy released to build glucose and fructose polymers
  • glucans and fructans deposited extracell providing sticky environment for plaque organism
  • ability of microorganisms to form plaque related to ability to synth polysacc
  • control targeted at GST

Q

Dental caries - The effect of diet on caries - factors? sugars? sucrose?

A

Factors:
- plaque composition influenced by diet
- S.mutans greater with high sucrose diets
- lactobacilli is acid tolerant and found in greater proportions in carious cavities and deep layers of plaque exposed freq to sugars
Sugars:
- sucrose, glucose, fructose, maltose, lactose and galactose
Sucrose:
- affects the composition of early plaque, leading to higher numbers of bacterial species capable of synth glucan from sucrose
- plaque bulkier with sucrose-rich diet in comparison
- encourages dextran prod in plaque due to energy released (sucrose broken down into 2 monosacc)
