Evidence-Based Prevention at Population Level

Evidence-Based Prevention at Population Level supports meeting P 3.4*. For dental nurses this means knowing the rationale for population approaches, reinforcing agreed messages and working within scope to keep care safe.

Prevention at community level includes universal measures for whole populations and targeted work for groups at higher risk. DBOH and NICE guidance recommend considering fluoride, diet, oral hygiene, smoking, alcohol and wider common risk factors when planning and evaluating interventions.

What to notice in practice

• Community prevention: consider factors beyond the single appointment that affect oral health or access to care.
• Evidence: identify what evidence supports an intervention and whether it applies to the local population.
• Risk: assess who is at higher clinical or access risk and whether the proposed approach addresses that.
• Reach: check whether an intervention will reach the intended groups or only those already engaged with services.
• Health gain: consider the likely benefit at population level, not just individual-level effects.

The dental nurse role is to explain why these measures are used, reinforce consistent messages from the team, and help avoid unsupported advice or actions that increase inequalities by only reaching easier-to-reach patients.

Practical good practice includes preparing for interactions, listening to patients and colleagues, checking understanding, handing over clearly, and reporting recurring problems so they can be addressed at practice level.

Research and system context

Evidence-based prevention should be effective, acceptable, proportionate and fair.
