Abstract
The present study aimed to determine the mesiodistal axial angulations of upper and lower permanent anterior teeth in young Iraqi adults having normal occlusion using postero–anterior cephalograph. Also to detect the sex difference in the mesiodistal axial angulations of such teeth. The sample consisted of 33 young Iraqi adult students, 17 males and 16 females aged 20–23 years old who were having Class I normal occlusion. Postero–anterior cephalograph was taken for each subject and was traced to determine the mesiodistal axial angulation of upper and lower permanent anterior teeth. The results revealed that the mean values of mesiodistal axial teeth angulations in both sexes showed very limited variation. No significant bilateral differences were found for right and left sides for both jaws (for males, females and total sample). From the above results, it could be concluded that no significant bilateral differences in mesiodistal axial tooth angulations were found for both jaws, for total sample and for both sexes. Also, male–female comparison showed no significant difference in mesiodistal axial teeth angulations and for both jaws.
