The relationship between tooth size and stature has been analysed extensively at the interspecies level but has received less attention at the intraspecies level. The relationship between these two parameters does not seem to be the same among modern human populations. The aim of this study is to analyse the relationship between tooth dimensions and body measurements in the Baka Pygmies. Height, weight, and tooth dimensions were obtained for 45 adult Baka females and 17 males from Le Bosquet (Cameroon). Correlations were obtained between the variables and compared to results for other human populations. The Baka population is distinctive in the small number of significant correlations. Only two buccolingual diameters among Baka females show any significant correlation with height. The lack of significant correlations between tooth dimensions and body dimensions among the Baka means that changes in body size are accompanied by random variations in tooth dimensions. The absence of correlations may be accounted for by the impact of environmental effects on the somatic growth of the Baka producing a Pygmy phenotype adapted to live in the forest. It is worth noting that many correlations become significant when sexes are pooled.
牙齿大小与身高之间的关系在种间水平上已得到广泛分析，但在种内水平上受到的关注较少。这两个参数之间的关系在现代人群中似乎并不相同。本研究的目的是分析巴卡俾格米人中牙齿尺寸与身体测量值之间的关系。从勒博斯克（喀麦隆）获取了45名成年巴卡女性和17名男性的身高、体重和牙齿尺寸。获得了变量之间的相关性，并与其他人群的结果进行了比较。巴卡人群的显著相关性数量较少，具有独特性。在巴卡女性中，只有两个颊舌径与身高有任何显著相关性。巴卡人牙齿尺寸与身体尺寸之间缺乏显著相关性意味着身体大小的变化伴随着牙齿尺寸的随机变化。相关性的缺乏可能是由于环境因素对巴卡人体生长的影响，产生了适应生活在森林中的俾格米表型。值得注意的是，当将性别合并时，许多相关性变得显著。
