Plaque index (PI) / oral hygiene · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
School-based interventions may reduce dental plaque scores (SMD -0.32, favouring intervention), but the certainty of evidence is very low.

Oral hygiene measured by mean gingival scores · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
The effect of school-based interventions on gingival scores is uncertain and not statistically significant (SMD 0.12; very low certainty).

Dental caries · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
Among children aged 6-8 years, DMFT scores were significantly reduced (SMD -0.11); subgroup not separately GRADE-rated.

Annual increment in DMFS (D3) · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
Oral-health-education interventions significantly reduced net increment in DMFS (SMD -1.05); no significant subgroup difference vs other interventions (P=0.74).

Dental caries prevalence measured by dmft or DMFT/S score greater than one · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
School-based interventions may reduce the prevalence of dental caries (RR 0.70, favouring intervention), but the certainty of evidence is very low.
