It is very uncertain whether the intervention changes FUNCTIONAL LIMITATIONS (very low certainty).

Longitudinal follow-up over time (natural caries progression; no assigned intervention) vs Within-cohort change from baseline to follow-up (>=3 y)

Annual increment in dmft (primary dentition) · Children (primary dentition, d3), Western or comparable populations

In the primary dentition, the annual dmft increment ranged from -0.3 to 0.3 across 4 studies; values were inconsistent because of tooth exfoliation and could not be pooled (ungraded).

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.
