Steiner's norms for North Indian pre-school children.

ABSTRACT

A roentgenographic cephalometric investigation to establish Steiner's norms in pre-school children was carried out on 60, 4-5-year-old North Indian children with complete normal established primary dentition and pleasing profiles. The North Indian children were found to possess a convex profile, steeper occlusal plane, steeper mandibular plane and more upright incisors over basal bone at 4-5 years of age as compared to that of Caucasian children. None of the measurements showed sexual dimorphism of any statistical significance. The Steiner's norms from a sample of Caucasian population are not as such applicable to North Indian pre-school children.
