Heritability of Caries Outcomes Adjusted for Age and Age²

Phenotype	h2	SE	p value	R2
Traditional DMFS index	0.42	0.16	0.007	0.05
DMFS1	0.27	0.17	0.057	0.03
DMFS2	0.54	0.18	0.003	0.04
DMFS3	0.43	0.15	0.004	0.10
DMFS4	0.00	-	0.500	0.03
DMFS5	0.40	0.16	0.008	0.08
Maxillarya	0.34	0.19	0.041	0.07
Mandibular	0.31	0.14	0.016	0.06

h² = heritability (i.e., the proportion of trait variation attributable to the cumulative role of genes).

SE = standard error of the heritability estimate.

R² = proportion of trait variation attributable to age and age²; unadjusted models were similar (results not shown).

^aDMFS5 may be subdivided into maxillary and mandibular components.
