Question · asked by 1 review

Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement) vs usual practice: Plaque index (PI) / oral hygiene

Population
Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
Intervention
Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement)
Comparison
usual practice
Outcome
Plaque index (PI) / oral hygiene

School-based interventions may reduce dental plaque scores (SMD -0.32, favouring intervention), but the certainty of evidence is very low.

How reviews are matched to this question

Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
