Dental Public Health
What this domain tests
Dental public health tests measurement of oral disease, survey methods, programme planning and evaluation, and the Kuwait context of a young, largely expatriate population served by public and private systems.
Core rules
- Prevalence is the proportion affected at a point in time; incidence is new cases over a period. A single cross-sectional survey cannot give incidence.
- DMFT and dmft count decayed, missing, and filled teeth; they do not measure severity of individual lesions or quality of life.
- Screening detects disease in individuals; surveillance monitors trends in populations.
- Planning cycle: assess need, set objectives, choose strategy, implement, evaluate, and revise.
- The Ottawa Charter actions are healthy public policy, supportive environments, community action, personal skills, and reorientation of services.
- Need differs from demand; equity means targeting the groups with the greatest burden.
- In Kuwait, desalinated water contains negligible fluoride, so water fluoridation is not a current population strategy; school programmes and clinical prevention carry the load.
Worked example
You are asked to plan a school sealant programme in one governorate. Reasoning: first measure caries prevalence in the target age group and the number of eligible children; set coverage objectives; train and license providers; arrange consent, infection control, and referral for untreated caries; evaluate coverage and sealant retention at 12 months.
Traps
Reporting incidence from one survey; confusing need with demand; evaluating only the number of children seen rather than outcomes.
