Facial soft-tissue analyses made from photographic records (photogrammetric analysis of the soft tissues) showed interracial dimorphism. Standard of these facial analyses, originally obtained from Caucasian might not be appropriate for the diagnosis and treatment planning of other groups of orthodontic patients. The purpose of this study was to compare the sagittal photogrammetric soft tissue profile characteristics between Senegalese and Moroccan adults.
A cross-sectional study was performed in a group of Senegalese and Moroccan students in the Faculty of Medicine, Pharmacy and Dentistry of Dakar. Standardized facial-profile photographs were taken with each student in natural head position, centric relation, and relaxed lip posture. Twenty four linear parameters were measured on paper sheet using a graduated ruler. For each variable mean and SD were calculated. In addition independent samples t-test was performed to detect sexual and racial dimorphism. Results were regarded as significant at p = 0.05.
Senegalese subjects had significantly more lips protrusion than Moroccan who had significantly a more elongated and more anterior positioned nose, a more chin prominence and a tendency to cutaneous class II than Senegalese.
Further studies including different age groups subjects would allow having longitudinal data according to age.
通过摄影记录进行的面部软组织分析（软组织摄影测量分析）显示出种族间的差异。这些最初源自白种人的面部分析标准可能不适用于其他正畸患者群体的诊断和治疗计划。本研究的目的是比较塞内加尔和摩洛哥成年人矢状面摄影测量软组织轮廓特征。
在达喀尔医学、药学和牙科学院的一组塞内加尔和摩洛哥学生中进行了一项横断面研究。在每个学生处于自然头位、正中关系和放松唇姿势时拍摄标准化的面部轮廓照片。使用带刻度的尺子在纸上测量24个线性参数。计算每个变量的均值和标准差。此外，进行独立样本t检验以检测性别和种族差异。当p = 0.05时，结果被视为具有显著性。
塞内加尔受试者的嘴唇前突明显多于摩洛哥人，摩洛哥人的鼻子明显更长且位置更靠前，下巴更突出，并且比塞内加尔人有皮肤II类倾向。
包括不同年龄组受试者的进一步研究将有助于获得按年龄的纵向数据。
