Prediction of adult height of girls from height and dental maturity at ages 6-10 years.

The relationship between height and dental development was studied in 56 healthy girls by the use of the chronological age at the references point of the eruption curve of the permanent teeth. There was a high correlation between age plus height at this reference point and adult height. When growth rate was taken into account, the correlation increased. It is thus possible to predict final body height from the age at which the eruption of the first twelve permanent teeth occurs plus the height at that time. The residual standard deviation of predicted adult height was 2.3 cm.
