    OBJECTIVES: We sought to determine whether American Indian tribe-based interventions that successfully prevented toddler dental caries in a 2005 cohort study (the Toddler Overweight and Tooth Decay Prevention Study, or TOTS) influenced the prevalence of dental caries in children ages 11 to 13 in the same communities ten years later (the TOTS-to-Tweens study). METHODS: We recruited original TOTS participants and conducted school- and community-based dental screenings at tribal communities that received family plus community-wide interventions (F + CW), community interventions only (CW) or were control communities. We also enrolled children who did not participate in TOTS, but were exposed to CW interventions or to the control environment. Trained clinicians examined children's teeth and recorded whether each tooth was decayed, missing or filled (DMFT). We calculated DMFT scores for each child and evaluated differences in DMFT incidence rate ratios (IRR) and components of DMFT by intervention group. RESULTS: We observed lower age- and sex-adjusted DMFT scores among F + CW children (a mean of 2.1 DMFT; 95% confidence interval [CI]: 1.4-2.7) and among CW children (2.2; 95% CI: 1.9-2.6), than control children (3.0; 95% CI: 2.3-3.7). The F + CW group had 32% lower DMFT scores than control children (IRR = 0.68; 95% CI: 0.46-1.01), and CW children had 26% lower DMFT scores than control (IRR = 0.74; 95% CI: 0.55-1.00). The proportion of children with filled teeth was higher in control than intervention communities (37.9% in F + CW, 47.1% in CW, and 67.1% in control, P = .002). CONCLUSIONS: Our findings suggest modest yet significant long-term effects of interventions that prevented toddler dental caries on the DMFT scores of tweens evaluated ten years later. Further study of effective interventions and their sustainability is clearly warranted among tribal children, who remain at high risk for dental caries.
