Abstract
Mean age at the eruption of the 1st deciduous tooth was calculated for the 10,443 children of a birth cohort in 1966 in northern Finland. Eruption was advanced by 1 wk on average in the 1559 children whose mothers had smoked during pregnancy, the difference between these and their controls being statistically significant. A regression analysis of the age at tooth eruption showed highly significant explanatory variables, in addition to maternal smoking, to be weight and height at birth and at 6 mo., and gestational age, while place of residence on a north-south axis was of lesser significance.
