617 schoolchildren 10-19 years of age were examined in order to assess the prevalence of malocclusion in a population sample in Lagos. Class I occlusion accounted for 76.8%, followed closely by Class II malocclusion, 14.7%, and Class III malocclusion, 8.4%. Crowding was recorded in 15.1% of the cases, most of which occurred anteriorly. The present study shows some interesting differences in the prevalences of malocclusions compared to studies on Caucasian subjects.
