A cephalometric study of antero-posterior skeletal jaw relationship in Nigerian Hausa-Fulani children.
OBJECTIVE
To determine the antero-posterior skeletal jaw relationship in Hausa-Fulani children in Nigeria.


METHODS
This study was carried out in 1998 at the Maxillo-facial unit of the Ahmadu Bello University Teaching Hospital, Kaduna, Nigeria.


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


CONCLUSIONS
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.
