A comparative study between two randomly selected samples from which to derive standards for craniofacial measurements.

The present study was performed to derive cephalometric standards for Saudi Arabian boys aged from 9-12 years. The sample was then compared with a British sample aged 9-12 years to detect statistical differences. The differences between both samples demonstrated a slightly prognathic Saudi face, more protrusive upper and lower incisors, and low Gonial and saddle angles.
