DIET + DENTAL CARIES
- MICRONICHE: susceptible areas ie just below contact point and fissures
- caries is fragile and vulnerable: can only proceed under certain conditions
- CARIOUS LESIONS are driven by the plaque biofilm
- Managing the biofilm can therefore arrest caries

- 2 MAIN THEROIES about carious process
- Historical and epidemiological studies
- 2 main types of study
- cross-sectional:different groups at one point in time
- longitudinal:follows a group over along period of time

- TRISTAN DE CUHNA
- Isolated volcanic island in south atlantic
- community of 300 people, volcanic eruption1961 evacuated to england
- they were dentally examined in 1962 and after they returned to island
- 2 earlier studies by Sampson+Sognnaes shows no caries in 6'sof 6-9yr olds
- but by 1962 increased to 50% and to 80% 1966
- in the 1950'sincreased communication with the outside world
- Higher incomes altered diet with refined fermentable carbs
- dramatic increase in caries as the result of an altered diet

- LONGITUDINAL/INTERVENTIONAL STUDY
- HOPEWOOD HOUSE
- Children were prohibited from eating sugary substances
- caries dropped dramatically
- study showed that the children had 16 times less decay than sydney
- Sydney children on average had 9.5 DMF teeth

- VIPEHOLM STUDY
- could never be performed and shouldn't have in the first place
- Highly unethical
- Mental hosp segregated into blocks that didn't mix
- 1 block given 0 toffees a day, the other 24 a day
- discovered that sugar between meals increased caries prevelance
- Sugar can be eaten up to x4 a day during meals with no significant drop in pH
