Overjet values of children and young adults in Lagos

Overjet values were studied in a stratified convenience sample of 820 Nigerians aged 15, 19, 20 and 21 years from Lagos educational establishments. There was no indication that between 15 and 21 years of age overjet values were age or sex dependent. The mean overjet value, which is one indication of antero-posterior occlusal relationship, is effectively the same in Lagos, Nigeria as it is in York, England.
