The interrelationships between facial areas and other body dimensions.

The data from 35 premenarchial Gujarati, Hindu girls, selected at random, in the age range of 120 months to 144 months were collected to find out statistically the nature and the values of correlation coefficients among various facial areas and other body dimensions such as body weight, stature, chronological and skeletal ages. The correlation coefficients between skeletal, chronological, height and weight ages ranged from 0.413 to 0.8105 showing moderately high association. Height and weight ages turned out to be the most reliable indicators of growth and development of facial areas in this age group and the chronological age as in ineffectual indicator of the same. Maxillary and mandibular areas showed a high value of correlation coefficients (0.67) while the orbitoethmoidal area did not show any correlation with any age variables or with other facial areas. The mandibular areas showed the highest correlation with weight age (0.63) and lowest with chronological age (0.431). The maxillary area showed highest correlation with chronological age (0.62) and lowest with skeletal age (0.42). Fifteen empirical formulae have been developed by which average value of facial areas could be predicted from the other variables.
