If enamel hypoplasia is present and vitamin D = 80nmol/L: dt = e (B intercept) x e (B enamel hypoplasia)(enamel hypoplasia) (B vitamin D)(vitamin D level) x e = e (0.32) x e (1.14)(1) x e (-0.011)(80) = 1.38 x 3.13 x 0.42 = 1.83 teeth affected with caries If enamel hypoplasia is absent and vitamin D = 80nmol/L: dt = e (B intercept) x e (B enamel hypoplasia)(enamel hypoplasia) (B vitamin D)(vitamin D level) x e = e (0.32) x e (1.14)(0) x e (-0.011)(80) = 1.38 x 1 x 0.42 = 0.59 teeth affected with caries Figure 5.1 – Predicted number <strong>of</strong> decayed primary teeth by 25(OH)D level and enamel hypoplasia status Predicted Number <strong>of</strong> Decayed Primary Teeth (dt score) dt score 3.5 3 2.5 2 1.5 1 0.5 0 3.3 2.53 1.83 1.06 0.81 0.59 Yes No Yes No Yes No deficient deficient mean level mean level adequate Enamel Hypoplasia and <strong>Vitamin</strong> D Level adequate The final Poisson regression model (Table 5.22) included those same independent variables that appeared in the expanded logistic regression model for ECC. Results reveal 5-28
that infant age, the presence <strong>of</strong> enamel hypoplasia, and maternal 25(OH)D levels during pregnancy were significantly associated with the presence <strong>of</strong> ECC in infants. The association between ECC and the health <strong>of</strong> the child was also significant (p=.037).
