Longitudinal follow-up over time (natural caries progression; no assigned intervention) vs Within-cohort change from baseline to follow-up (>=3 y)
Caries incidence rate (first D3 lesion) per person-year at risk (permanent dentition) · Children and adolescents (permanent dentition, D3, up to 21 y), Western or comparable populations
In the permanent dentition, the pooled caries incidence rate was 0.11 per person-year at risk (95% CI 0.09 to 0.13; random-effects meta-analysis of 15 studies), i.e., about 11 of every 100 caries-free persons develop dentine caries each year (ungraded).
