Q

What is the role of clinical evidence in caries risk? (3)

A

CARIES EXPERIENCE:
- dmft/DMFT > = 5 (primary/permanent dentition)
- Caries in 6’s at 6years
- 3 years caries increment > = 3
> or equal to 10 initial lesions in primary dentition at 1st attendance

ORTHODONTICS:
- Fixed appliance therapy

PROSTHETICS:
- Fixed or removable

Q

What is the role of diet in caries development? (4)

A

> = 3 sugar intakes per day

  • High frequency is an issue over the volume of sugar
  • Highly processed/refined carbs are more cariogenic than natural sugars (sucrose more cariogenic than glucose+ fructose)
  • Natural sugars still cause harm (lactose in early childhood caries

Q

Functions of fluoride

A
  1. Fluoride + enamel crystals forms fluoroapatite, which is more caries resistant/to demineralisation than hydroxyapatite
  2. Bacteriocidal
    Resistant to strep strains
  3. Interferes with the adhesion force of bacteria, reducing their ability to stick to teeth surface

Q

How can poor oral hygiene stimulate caries development (5)

A
  1. Poor technique
  2. Irregular brushing
  3. Unassisted (very young/very old/manual dexterity issues)
  4. Access to toothbrush
  5. Difficulty due to changes
    - Mixed dentition
    - Ortho
    - Gaps
    - Recession
