What were the goals set by WHO for the year 2000 set in 1981?
|
50% of 5-6-year-olds free of caries experience
Mean DMFT at age 12 not to exceed 3 85 % of population should have all their teeth at age 18 50% reduction in edentulousness at age 35-44 25% reduction in edentulousness at age 65 Establish a database for monitoring changes in oral health |
|
What are the goals set by WHO for the year 2020?
|
To increase the proportion of caries free 6-year-olds by X%
To reduce the DMFT, particularly the D component, at age 12 by X%, with special attention to high-risk groups within populations To reduce the number of teeth extracted due to dental caries at ages 18, 35-44 and 65-74 by X% |
|
Why is there a sudden rise in prevalence of dental caries in developed countries rather than developing countries in the mid 20th C?
|
due to high consumption of refined carbohydrates which was not available in developing countries at the time
|
|
In the past 20 years developed countries have decreased caries prevalence. Why?
|
Better oral hygiene, sensible approach to sugar consumption, effective use of fluorides, public health preventative programmes
|
|
Childrens caries prevalence in permanent dentition (DMFT) increase at double rate from the age of 12 onwards. Why would this be?
|
2nd permanent molar erupts at age of 12. Other molars erupt after 12. (More prone)
|
|
Small percentage taken up by M component in a population would mean what?
|
More treatment is done to keep the tooth rather than extracting it.
|
|
Rank the order of teeth susceptible to caries
|
1. mandibular first and second
2. maxillary first and second 3. premolars except mandibular first premolar and maxillary incisors 4. maxillary canines and mandibular first premolar 5. mandibular incisors |
|
Why is there a decline in the graph between 8 to 10 year olds?
|
The primary molar is being shed. Not included in DMFT
|
|
Caries experience will differ between developing and developed countries, from one region to another and also within countries themselves. Why?
|
Due to variable local determinants of disease that prevail in those areas.
|
|
In most developing countries, the level of dental caries was low until recent years but prevalence rates of dental caries and dental caries experience are now tending to increase. Why?
|
Influenced by the adoption of a more western style diet containing high amounts of fermentable carbohydrates, lack of preventative programmes and primary dental services, increasingly younger populations, low fluoride exposure and increasing consumption of sugar.
|
|
In the developed countries a decline in caries has been observed over the past 20 years. Why?
|
due to improved oral hygiene, a more sensible approach to sugar consumption (not necessarily less), effective use of fluorides, public health preventative programmes and changing living conditions and life styles.
|
|
The deciduous maxillary anterior teeth are most susceptible. Suggest a reason for why.
|
Mainly due to feeding habits of children.
