Dental caries increment, DMFT/dmft (whole-tooth level) · Children in school or kindergarten settings (aged 3-14 years)

Oral microbial community composition and diversity (other caries-associated taxa; alpha- and beta-diversity) · Systemically healthy individuals (children and adults, aged 40 months to 50 years) assessed for dental caries
No oral microbial taxon other than S. mutans was consistently associated with caries; alpha-diversity mostly did not differ between caries-active and caries-free groups and beta-diversity findings were mixed (ungraded, narrative).
