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

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.

Higher JIA disease activity/severity (e.g., high JADAS/activity scores, polyarticular RF-negative subtype, active disease, anti-TNFalpha or cyclosporine medication) vs Lower JIA disease activity / inactive or milder JIA

Prevalence and severity of oral and TMJ diseases/conditions (periodontal status and dental caries) · Children and adolescents with juvenile idiopathic arthritis (JIA)

Some studies suggested greater JIA disease activity/severity (and certain medications) was associated with worse periodontal and caries outcomes, but small samples meant no solid conclusion could be drawn (ungraded).

Slum / urban-disadvantaged setting vs Non-slum urban / general-urban / national population

Dental caries prevalence · Adult residents of slums and non-slum urban settings of LMICs

Dental caries prevalence in LMIC urban/slum populations ranges widely (13%-76%); not GRADE-rated (narrative synthesis).

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · Healthy children and adolescents in the United Arab Emirates

Dental caries is highly prevalent among children and adolescents in the UAE, ranging from 22% to 99.4% across cross-sectional studies (narrative synthesis; not GRADE-rated).

Dental caries prevalence · Children (<18 years) with intellectual and developmental disabilities (IDD) in India

Dental caries affects about 64% of children with IDD in India (pooled prevalence 0.64, 95% CI 0.45-0.79; high heterogeneity; ungraded).
