Correlations among Tooth Sizes in a Sample ofOregon Caucasoid Children

The simple correlations of tooth size for all pairs of deciduous and/or perma­nent teeth except second and third permanent molars were calculated from the cast models for a sample of 116 children and compared with correlations reported by other investigators. While most of the correlations do not differ significantly from correlations derived elsewhere, more differ than would be expected by chance alone. Multiple and canonical correlations are also presented in order to show relationships among teeth and among arches
