- Reduced in both WW1+2
- Now declined
- Increase in 1983 in Undeveloped countries
- Worse than in developed countries
- 70's- early 80's 30-50% decline
- Except Poland, Russia, Italy+Germany.
- Shift in frequancy distribution/area on tooth
- 76% of disease in 25% of population
- Roor caries on increase
- Population living longer, keeping teeth for longer
- WHY?
- Fluoride
- Marthaler (1984) stated main reason for decline
- Russia and Germany were not using flouride, High caries rate showed
- Dietary modifications
- High DMFT, high sugar diet
- Adding sugar to bottles decreased
- Sweetend dummies decreased
- Changes in formula/baby foods
- Changes in diagnostic criteria
- No sharp probing of dental caries
- reduction in premature caries lesion treatment
- Practice of preventative fillings decreased
- Social economic factors
- Higher social group, lower rate
- Overal improvement of living
- Single parent/unemployed
- 3 year old increase from 4-10% in single parent/unemployed
- Cyclical Variations
- Many diseases often have a prevalence which varies with time, following cyclical, rhythmical patterns
- But no evidence to support this
- Dental services
- Increased dental manpower has contributed MINIMALLY to the decline
- Widespread use of antibiotics
- Loesche (1982) Found relationship in more use of antibiotics and decline in caries.
- Germany and Swizerland, similar antibiotic use. Germany did not decline
- Oral Hygiene
- No evidence that toothbrushing reduces caries.
- Increase in OH in last 2 decades, no significant decline in caries
