Correlation between dental maturity, height development and sexual maturation in normal girls.

The correlation between the dental maturity and the different measures of sexual development, i.e. the age at menarche, the ages at breast and pubic hair development, and the age of peak height velocity, was found to be low in healthy girls. Multiple regression analyses between the predictors height and growth rate at the chronological age of a certain stage of the dental development and each of the predictands age at menarche, breast development, and age of peak height velocity improved the residual standard deviation significantly in comparison with the standard deviation of the distribution of these variables.
