OBJECTIVE:To evaluate the dental facial symmetry in normal Shanghai adults occlusion with posterioanterior cephalometric roentgenography. METHODS:Posterioanterior films of the 92 adults subjects with normal occlusion were measured. Five facial midlines commonly used in posterioanterior cephalometric were analyzed according to the middle structure index and side middle structure index. The midline deviations were measured. RESULTS:The middle line through ANS and perpendicular to zygomaticofrontal line has less mean of middle structure index and side middle structure index. There are midline deviations in population with normal occlusion.CONCLUSION:The facial midline mentioned above was suitable for posterioanterior cephalometrics, but the reliability is not absolute. Normal occlusion also has midline deviations. The asymmetry of face was larger than that of dental occlusion.
