Dental caries prevalence in permanent teeth (cavitated lesions) · Children aged 11-13 years in Latin America and the Caribbean

In Brazil, pooled permanent-teeth caries prevalence in 11-13 year-olds was 56% (95% CI 53-60%), with a significant declining trend over time; certainty not graded.

Dental caries prevalence in permanent teeth (cavitated lesions) · Children aged 11-13 years in Latin America and the Caribbean

About 58% of 11-13 year-old children in Latin America and the Caribbean had dental caries in permanent teeth (95% CI 54-61%); certainty not graded.

Clinical examination with 24-month recall vs Clinical examination with 6-month recall

Dental caries: prevalence of moderate to extensive caries (ICDAS 3-6) · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with 24-month recall showed no clear difference in dental caries: prevalence of moderate to extensive caries (ICDAS 3-6) compared with clinical examination with 6-month recall (low certainty).

Clinical examination with risk-based recall vs Clinical examination with 6-month recall

Dental caries: prevalence of moderate to extensive caries (ICDAS 3-6) · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with risk-based recall showed no clear difference in dental caries: prevalence of moderate to extensive caries (ICDAS 3-6) compared with clinical examination with 6-month recall (moderate certainty).

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).
