Older adults (population mean age >33.4 years) vs Younger adults (population mean age <=33.4 years)

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

Studies of older adults (mean age >33.4 years) had higher pooled DMFT than younger adults, but the age to DMFT meta-regression was not statistically significant; ungraded observational evidence.

Populations with low socioeconomic status (>=22.4% of the population with low SES) vs Populations with higher socioeconomic status (<22.4% of the population with low SES)

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

Populations with a higher proportion of people with low socioeconomic status had higher caries experience (pooled DMFT 15.99 vs 5.50), and meta-regression associated low SES with higher DMFT (about 10.35 more DMFT per unit; p=0.050); ungraded observational evidence.

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.

HDI (quantitative) 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.

Populations with a low level of schooling (>=33.60% of the population with low schooling) vs Populations with a higher level of schooling (<33.60% of the population with low schooling)

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

Population level of schooling was not significantly associated with caries experience (DMFT) in subgroup meta-analysis or meta-regression; ungraded observational evidence with very high heterogeneity.

Illicit drug use vs People who do not use drugs

DMFT/DMFS index (dental caries experience) · People who use drugs (PWUD): methamphetamine, heroin, opiate, cannabis and cocaine users

Illicit drug use was associated with substantially higher odds of dental caries experience (DMFT) (pooled OR 4.11, 95% CI 2.07-8.15; 7 studies; high heterogeneity I2=90.5%; ungraded).
