Abstract:
砄bjective: To assess interexaminer errors in traditional cephalometric analysis so as to improve the accuracy . Methods : Ten cephalometric radiographs were selected randomly and 12 angular and 5 liner parameters were measured by 5 orthodontists in one week according to the original landmarks. The results were quantified with that of computer based. Results: The mean errors of some measurements were larger than 0.5, such as SL,GoGn SN, SE,FMA,FMIA,OP SN, 1 1 ,IMPA and SNA,while only those of SL and GoGn SN were larger than 1.0. Conclusion: Statistical significant differences are found in the The errors of measurements which need assisted line among the examiners but not found in the errors between angle measurements and liner measurements?
