Primary dental health aide (PDHA) service-delivery models (PDHA program; PDHA + intensive staffing; PDHA + robust prevention) vs Baseline pre-intervention service-delivery scenario

Projected mean DMFT (children below 5 years) · Alaska Native children (below age 18)

A simulation projected mean DMFT in children under 5 would fall from 7.4 to 4.9 under the PDHA model (certainty not graded).

Institutionalization (living in an orphanage/institution) vs Parented children living with their families

Caries in primary teeth: dmft (3 years) · Institutionalized orphan children (roughly 3 to 18 years)

Primary-teeth caries experience (dmf) was higher in institutionalized children than parented children but not significantly so (pooled MD 0.64; very low certainty).

Institutionalization (living in an orphanage/institution) vs Parented children living with their families

Mean DMFT (decayed, missing, filled permanent teeth) · Institutionalized orphan children (roughly 3 to 18 years)

Permanent-teeth caries experience (DMF) was marginally higher in institutionalized children but essentially similar to parented children (pooled MD 0.09, not significant; very low certainty).

Not applicable (single-group prevalence) vs Not applicable

Caries experience (mean DMFT) · Children aged 12 years (plus or minus one year) in Africa

The pooled mean DMFT score was 1.0900 (95% CI 0.9143 to 1.2657); GRADE was not reported.

Dementia (any type or severity) vs Older people without dementia

Caries experience (mean DMFT) · Older people (aged 60 years or older) with dementia

The DMFT index was similar between groups, with only 1 of 5 comparative studies finding a significant difference; no meta-analysis was performed (ungraded).

Low socioeconomic status (>22.4% of the population) vs Not applicable

Dental caries · Adult participants in 25 meta-regression studies
