Abstract
Objective: One of the most important components of orthodontic diagnosis and treatment
planning is an evaluation of the patient's soft tissue profile. An assessment of the nasolabial
angle is a vital component of this evaluation. The purpose of this study was to establish norms
for the nasolabial angle of an adult Nigerian population; compare the male and female values
and to compare the values obtained for Nigerians with those reported for other populations.
Method: Lateral cephalometric radiographs of one hundred students (44 males and 56
females) of the College of Medicine, University of Lagos, aged 18-25years were taken.
Selected subjects were of Nigerian ancestry with normal occlusion. The radiographs were
manual ly t raced and the nasolabial angle of each subject measured.
0 0 Result: A mean value of 84.35 +13.71 was computed for the entire sample. No statistically
significant difference was observed between the male and female values (p>0.05), although
0 0 the males recorded a lower nasolabial angle (83.70 ) than the females (85.28 ).The nasolabial
angle recorded in this study was similar to that reported for South African blacks, but much
lower than that reported for Caucasian populations.
0 Conclusion: The mean nasolabial angle of 84.35 + 13.71 was observed in the Nigerian
population studied. Sexual differences were not observed; however, the values observed in
this study differ from that reported for Caucasians and other racial groups.
