Abstract
OBJECTIVE: To determine the antero-posterior skeletal jaw relationship in Hausa-Fulani children in Nigeria. SETTING: This study was carried out in 1998 at the Maxillo-facial unit of the Ahmadu Bello University Teaching Hospital, Kaduna, Nigeria. MATERIALS AND METHODS: 100 subjects aged 11-13 years of Hausa-Fulani ancestry with no previous orthodontic treatment were selected for the study. Lateral cephalometric radiographs were traced and analysed to produce values for SNA, SNB and ANB. RESULTS: The mean SNA was 82.4 degrees, mean SNB 803 degrees and mean ANB 2.1degrees The normal range of ANB values was 0.5 degrees-4 degrees CONCLUSION: The values obtained differ from those of other population groups and should be used as guidelines in the orthodontic treatment of the ethnic group studied.
