Abstract:
This study was performed to evaluate the reproducibility of natural head position according to skeletal malocclusion types and sex using cephalometric radiographs for establishing orthodontic diagnosis and treatment planing. The sample consisted of 90 young adults (male 45, female 45) who had the skeletal malocclusion. Cephalometric radiographs were taken on natural head position, and statistical analysis was performed and method error of 6 postural variables were estimated to evaluate the reproducibility of the natural head position. The following results were obtained: 1. In the reproducibility of the natural head position, postural variables had no statistical significance in male and female(P>0.05) 2. In the reproducibility of the natural head position, postural variables had no statistical significance in Class I, II, III and total group (P>0.05). 3. The reproducibility of natural head position using method error was excellent in all group.
