Diet, Disease and Teeth Flashcards
What can dentition tell us about remains?
Food Consumed in the past
Patterns in consumption
Temporal Changes (over time)
Stages in economic evolution
Dental disease varies between…
Ages
Sexes
Geographic location
Temporally (over time)
Give the 3 parts of diet reconstruction
Chemical Signatures
Dental Microwear
Dental disease
What are chemical signatures used for in diet reconstruction?
Stable C isotopes
Terrestrial (C12) vs Marine (C13) protein
Age of weaning (N14/N15)
What are dental microwear marks used for in diet reconstruction?
dental pits and scratches gives diet hardness and dietary abrasiveness
What are dental diseases used for in diet reconstruction?
e.g.
caries -> dietary carbohydrates
What are the places of dental decay?
Caries
Root surfaces
Crown
What are dental caries?
Localised demineralisation of dental hard tissue by bacteria
Where are adults more likely to have dental decay?
Root Surfaces (along the gumline) , crown in juveniles
3 factors that cause dental decay?
Plaque (oral bacteria, organic substrate)
Bacteria
pH (plaque makes higher aciditiy)
Give the 6 influencing factors of dental decay
Carbohydrates Dental anatomy (nooks and crannies) Saliva (anti bacterial factors + pH) Sex Age Environment (minerals - fluoride, selenium..)
What is the carbohydrate that mostly affects dental decay?
Monosaccharides
what are the 4 stages of dental decay?
- Brown/Hyperwhite spot
- Enamel Erosion
- Dentine exposure
- Pulp cavity exposed
After the 4 stages of dental decay, what can occur
Abscess - infected tissue can get into the blood supply
How would you calculate the % of people with carious teeth?
No. People affected / Overall number of people * 100
