The actual size of each image was calibrated in millimeters based on the known distance of 10 mm between the two fixed points on the cephalostat rod in the radiograph.
Both pre and postoperative lateral cephalograms were taken with the same equipment and parameters: Orthoralix 9200 GENDEX (Dentsply[R], Des Plainnes, USA), cephalostat regulated at 70 kVp, 10 mA, 1.2 seconds exposure time, Kodak TMat G/RA films (18 x 24 cm, Carestream Health[R], New York, USA), with their metallic cassette and intensifying screen (Kodak Lanex Medium Extraoral Imaging Screens X-Omat).
A head stabilizing device called a cephalostat is used to maintain a standard position and object-image distance so that serial radiographs can be more accurately compared.
More accurate quantitative information was derived from longitudinal experiments arising from the development of the Cephalostat by Broadbent in 1931.
The cephalograms were taken with the subjects standing and the head positioned in the cephalostat and orientated to the Frankfort horizontal plane with the teeth in maximum intercuspation.
A portable cephalostat was specifically confected for the present study and consisted of a metal structure with an acrylic part to which the ear rods were attached.
Lateral cephalograms were obtained for all the subjects with teeth in centric occlusion, lips relaxed, cephalostat support and ear rods positioned.
Standard lateral cephalometric radiographs of the heads were obtained using standard cephalostat. The cephalograms were divided in two groups according to gender (male and female).
Lateral cephalometric radiograph of each individual was taken with a universal counter balancing type of cephalostat at Radiology Department of Khyber College of Dentistry, Peshawar.
All the lateral cephalometric radiograph of each individual were taken with a universal counter balancing type of cephalostat at Radiology department of Khyber College of Dentist- ry, Peshawar in natural head position.
