A cephalometric lips analysis and its relation to other cephalometric measurements in Iraqi adult individuals

الملخص EN

Background : The aim of this study was to evaluate and analyze the effect and behavior of the upper and lower lips in class I Iraqi subjects.

Material and methods : True lateral cephalometric radiograph of the sample that comprises 60 females and 50 males aged 18-25 years and they possess class I skeletally and dentally.

All the data have been analyzed by mean of AutoCAD computer programs where 9 cephalometric angles have been analyzed.

Results : In males the mean value of lower lip inclination, the upper lip inclination, and interlabial angle have no significant difference with that in females, so the mean values are 81.03, 84.2, and 158 respectively.

The lower lip is correlated with F.

man., upper lip inclination, interlabial angle, interincisal angle, upper and lower incisor inclination.

The upper lip inclination is correlated with SGn.

FH., F.

man., interlabial angle, interincisal angle and lower lip inclination.

Interlabial angle is correlated with upper lip inclination, interincisal angle, lower lip inclination, and upper central incisor inclination.
