Health Promotion Theories in Dentistry
On this page
Direct answer
Telling a patient to brush better rarely changes behaviour; theories of health promotion exist because information alone does not. The Health Belief Model (Rosenstock, extended by Becker into dental research) predicts action from perceived susceptibility, severity, benefits and barriers, nudged by cues to action and self-efficacy; the transtheoretical or stages-of-change model (Prochaska and DiClemente) matches the message to where the person is — precontemplation, contemplation, preparation, action or maintenance; Bandura's social cognitive theory makes self-efficacy the engine of change; and Ajzen's theory of planned behaviour routes intention through attitudes, social norms and perceived control. Above the individual level sits the Ottawa Charter (WHO, 1986, first International Conference on Health Promotion), whose five action areas — build healthy public policy, create supportive environments, strengthen community action, develop personal skills, reorient health services — with its advocate-enable-mediate strategies define health promotion as socio-political work, distinct from health education's classroom. Planning frameworks such as PRECEDE-PROCEED tie the whole apparatus into programme design.
What you must remember
- Ottawa Charter 1986: five strategies verbatim — build healthy public policy, create supportive environments, strengthen community action, develop personal skills, reorient health services — plus three approaches: advocate, enable, mediate.
- Milestones that frame the field: Lalonde Report 1974 (health fields beyond health care), Alma-Ata 1978 (Health for All by 2000, primary health care), Ottawa 1986, Jakarta Declaration 1997 (first in a developing country, 21st-century priorities), Bangkok Charter 2005.
- Health Belief Model constructs: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, self-efficacy — the model Becker applied to dental behaviours.
- Stages of change: precontemplation, contemplation, preparation, action, maintenance, with relapse as expected recycling — interventions matched to stage, so a precontemplator needs consciousness-raising, not an action plan.
- Self-efficacy (Bandura): the belief that one can perform the behaviour, built through mastery experiences, modelling, persuasion and reducing barriers — the strongest predictor of sustained brushing or quitting.
- Theory of planned behaviour (Ajzen): intention driven by attitude toward the behaviour, subjective norms and perceived behavioural control.
- PRECEDE-PROCEED (Green and Kreuter): planning from desired outcome backwards through predisposing, reinforcing and enabling factors, then implementing and evaluating — the bridge between theory and the district programme.
- The education-promotion distinction: health education develops knowledge and skills in individuals; health promotion creates the policy and environmental conditions in which those skills can succeed — sugar taxation and school policies are promotion, a lecture is education.
Where students slip
The predictable slip is reciting the Ottawa five as an abstract list; the earning move is giving each strategy a dental example — sugar-sweetened beverage taxation and gutkha bans as healthy public policy, school brushing programmes with provided paste as supportive environments, panchayat-led fluorosis committees as community action, chairside brushing instruction as personal skills, and NOHP integration into primary care as reorienting health services. The second confusion is education versus promotion — asked to "promote oral health", students describe lectures; the examiner wants the socio-environmental layers. Third, the HBM trap: candidates forget cues to action and self-efficacy, the late-added constructs that complete the model.
Frequently asked questions
What are the five action areas of the Ottawa Charter?
Building healthy public policy, creating supportive environments, strengthening community action, developing personal skills, and reorienting health services.
Which Health Belief Model constructs predict preventive behaviour?
Perceived susceptibility and severity, perceived benefits and barriers, cues to action, and self-efficacy.
How do the stages of change guide tobacco counselling?
By matching intervention to readiness — consciousness-raising for precontemplators, motivational resolution of ambivalence for contemplators, quit plans and skills for those in action, and relapse management as recycling.
What does PRECEDE-PROCEED contribute to dental programme planning?
A structure that works backwards from health outcomes through predisposing, reinforcing and enabling factors before implementation and evaluation.
How does health promotion differ from health education?
Education builds individual knowledge and skills, while promotion engineers policy, environmental and community conditions that make healthy choices feasible.
