Cephalometric study of craniofacial morphology on children with normal occlusion in Tianjin

Objective In order to establish the normal value of radiographic cephalometry of Tianjin and to reveal the regular pattern and the characteristics concerning the growth of craniofacial morpholopy.Methods 70 students with early permanent dentition were selected as the samples.The cephalometric analysis methods of Downs?Tweed and Steiner were used in this study.Results The normal value of radiographic cephalometry for early permanent dentition on normal occlusal children of Tianjin were established and compared with Beijing?Xian?Harbin?Shanghai.Conclusion The results suggest that the cephalometric mearsuement values are various in different regional population.
