Populations in countries with a lower Human Development Index (high category, HDI <0.800) vs Populations in countries with a higher Human Development Index (very high, HDI >=0.800)

Caries experience (mean DMFT) · Adults aged 19-60 years

Pooled caries experience (DMFT) was similar in very-high-HDI and high-HDI countries, and meta-regression found no significant association between national HDI and DMFT; ungraded observational evidence with very high heterogeneity.

Lower family socioeconomic status / income vs Higher socioeconomic position

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

Evidence on socioeconomic status/income and caries was inconsistent: some studies linked lower income to higher caries while others found no association (narrative synthesis; not GRADE-rated).

Oral Health of Children and Adolescents in the United Arab Emirates: A Systematic Review of the Past Decade. 2021 All outcomes
UAE; schools (Ajman, Dubai)
Findings were contradictory. Hashim et al. found children from low-income families had higher odds of severe early childhood caries (OR 1.43, 95% CI 1.11-1.85), and Ahmad et al. reported significantly higher DMFT in…

Lower parental (maternal/paternal) education vs Higher parental education

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

The association between parental education and caries was inconsistent; father's (but not consistently mother's) education was inversely associated with caries in some studies (narrative synthesis; not GRADE-rated).

Oral Health of Children and Adolescents in the United Arab Emirates: A Systematic Review of the Past Decade. 2021 All outcomes
UAE; schools/nurseries
Maternal education was not associated with children's caries in the Hashim et al. studies, whereas father's educational level was negatively associated with DMFT in Khadri et al. (secondary-aged children: -0.35, 95% CI…

Populations with a lower proportion of university-educated people (<33.78% with university level) vs Populations with a higher proportion of university-educated people (>=33.78% with university level)

Caries experience (mean DMFT) · Adults aged 19-60 years

The proportion of university-educated people was not associated with caries experience (DMFT); pooled DMFT was similar across subgroups and the meta-regression was non-significant; ungraded observational evidence.
