عنوان فارسی Evaluation of the Outcome of Removable Orthodontic Treatment Performed by Dental Undergraduate Students
چکیده فارسی مقاله Statement of problem Comprehensive diagnosis is regarded as an important base for orthodontic treatment. An effective way to reach a correct diagnosis is to compare the craniofacial skeleton of patients with normal cases in the same race through lateral cephalograms. Purpose The present study was designed to determine the cephalometric standards of senior high school students in the city of Hamadan and compare with results of other studies. Material & Methods According to the normal occlusion definition, 25 girls and 27 boys aged 17-20 years were selected. They did not have any facial malformation and history of orthodontic treatment. Lateral cephalograms were obtained in Natural Head Position. Twenty two cephalometric variables were measured three times. Student t -test used in order to analyze the results. Results The length of anterior cranial base of girls and boys (72.5 +3.7 , 76.8+3.7) were significantly less than Michigan standards for girls and boys (76.9+3.9,83.3+3.8) (p< 0.005). There was a significant tendency to more straight profile and forward rotation of mandible (88.3+4.6, 89.6+2.7) in this study vs. Cook's (80.8+3.1, 82.1+2.2) (p< 0.005). Linear measurements of boys were generally greater than of girls. Conclusion It is important to consider ethnic and racial variations and sex differences in preparing problem list and treatment planning.
