OBJECTIVE To identify cephalometric norms for a Jordanian population. METHODS A cross sectional study using a sample selected on the basis of a balanced face and a Class I occlusion. METHODS 65 subjects aged 14-17 years were selected from a larger sample on the basis of Class I incisors, a balanced profile and no previous orthodontic treatment. Lateral skull radiographs were digitised directly to produce values for SNA, SNB, ANB, UI/MX, LI/MN, UI/LI, MMPA and LI/A-Pog. RESULTS SNA and SNB were very close to the Eastman Standards. MMPA was significantly lower in Jordanians whilst UI/MX and LI/MN were significantly higher. Lower incisors were 4.6 mm further forward in relation to A-Pog in Jordanians.
