Bimaxillary protrusion in the Palestinian population.

OBJECTIVE: To study the prevalence of bimaxillary protrusion among Palestinians. MATERIALS AND METHODS: Cephalometric radiographs for 79 normal occlusion adult Palestinian university students were traced. RESULTS: The interincisal angle was decreased in the Palestinian women compared to the Caucasian means, but this had no impact on lip protrusion. CONCLUSION: Relative to Caucasian cephalometric norms, Palestinians show no extraoral bimaxillary protrusion features, and therefore, these norms can be applied to Palestinian faces.
