A cephalometric study of antero-posterior skeletal jaw relationship in Nigerian Hausa-Fulani children

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 82.40, mean SNB 80.30 and mean ANB 2.10. The normal range of ANB values was 0.50-40. 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.
