Odds of higher caries (DMFT) category · 12-year-old children across European countries (national/regional epidemiological surveys, 2011-2022)
Unemployment rate was not independently associated with DMFT category in the adjusted model (OR 0.99, 95% CI 0.44 to 2.23); not GRADE-rated.

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.

Dental caries in children · Mother-child pairs
In one cross-sectional study, higher maternal allostatic load was associated with child dental caries experience and with health-related maternal care-taking behaviours; not pooled (ungraded).

Caries experience (mean DMFT) · 12-year-old children across European countries (national/regional epidemiological surveys, 2011-2022)
Mean DMFT tended to increase with unemployment rate (low 1.23, medium 2.08, high 2.38; ANOVA p<.05); descriptive country-level means only, not meta-analyzed or GRADE-rated.

Poor oral health-related quality of life (OHRQoL) · Children aged 3-12 years

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).
1 finding from 1 review
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…

Early childhood caries (ECC) · Healthy children under 6 years of age (6 months to 6 years); preschool children
After excluding an extreme outlier (Alhabdan 2018), the association between low brushing frequency and ECC remained statistically significant (pooled OR approximately 2.0, p=0.003; I2=87.5%); the exact estimate and its CI were not reported; ungraded.

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).
1 finding from 1 review
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…

Poor oral health-related quality of life (OHRQoL) · Children aged 3-12 years

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years
Fluoride toothpaste 440 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1450 ppm (higher concentration) (moderate certainty).
