Facial soft tissue thickness in a sample of Sudanese adults with different occlusions

Sexual dimorphism was noted, with males having thicker facial soft tissue at all measured points. The facial soft tissue thickness varied among different occlusions. Individuals with skeletal class II occlusion had the thickest lower lip, and class III individuals had the thickest upper lip. In general, the Sudanese sample had a unique spectrum of measurements, with thick upper and lower lips, compared with African and Caucasoid subjects, pointing to the need for ethnic-specific data.
