In the permanent dentition, the annual DMFT increment ranged from 0.06 to 0.73 across 14 studies, and was higher where baseline caries experience was higher (descriptive range; ungraded).

Dental caries: dmfs increment (primary teeth) · Children (primary dentition, d3), Western or comparable populations

In the primary dentition, the annual dmfs increment ranged from -1.0 to 1.0 across 7 studies; values were inconsistent because of tooth exfoliation and could not be pooled (ungraded).

Annual decline in percentage of caries-free children (primary dentition, d3) · Children (primary dentition, d3), Western or comparable populations

In the primary dentition, the annual decline in the percentage of caries-free children ranged from 3.8% to 12.2% across 6 studies (descriptive range, no pooled estimate; ungraded).

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).
