This study aimed to document the angulation, inclination, and facial anatomical characteristics of teeth in a select South African population to determine if there are any population norms. Digital intra-oral scans were used, to analyze the morphology of teeth and measure the facial clinical crown. : A quantitative observational research design with 60 3D intra-oral scans of a select South African population group was used. Morphometric analysis of 3D intra-oral scans was performed for a select South African population group, measuring the clinical crown height, width, angulation, and inclination of each tooth. : Significant differences in crown widths between male and female subjects were observed for several teeth in the maxillary and mandibular arches: males exhibited larger mean widths and larger crown dimensions than females. The South African Black group showed more sexual dimorphism compared to the South African Indian group. Clinical crown length and tooth angulation differed significantly between South African Indian and South African Black populations, while crown width and inclination remained consistent across these population groups and crown inclination between sex groups. : Certain teeth exhibited notable variations between South African Indian and South African Black population groups; specifically, crown length and angulation had significant differences, whereas crown inclination and width remained consistent across these population groups.
本研究旨在记录特定南非人群牙齿的角度、倾斜度和面部解剖特征，以确定是否存在任何人群标准。使用数字化口腔内扫描来分析牙齿形态并测量面部临床冠。：采用定量观察性研究设计，对特定南非人群组进行了60次三维口腔内扫描。对特定南非人群组的三维口腔内扫描进行形态计量分析，测量每颗牙齿的临床冠高度、宽度、角度和倾斜度。：在上颌和下颌弓的几颗牙齿上观察到男性和女性受试者之间的冠宽度存在显著差异：男性的平均宽度和冠尺寸比女性大。与南非印度人群组相比，南非黑人组表现出更多的性别二态性。南非印度人和南非黑人人群之间的临床冠长度和牙齿角度存在显著差异，而冠宽度和倾斜度在这些人群组之间以及性别组之间的冠倾斜度保持一致。：某些牙齿在南非印度人和南非黑人人群组之间表现出显著差异；具体而言，冠长度和角度存在显著差异，而冠倾斜度和宽度在这些人群组之间保持一致。
