Deciduous tooth dimensions of a recent archaeological sample of 37 boys, 18 girls and 88 children of unknown sex from London were measured. Mesiodistal (maximum breadth at the contact point) and buccolingual measurements were recorded. A gradient of size variation was apparent with anterior teeth showing the highest variation and second molars the least. In general, the teeth of the children of Spitalfields were smaller than those of other groups from various archaeological and contemporary populations. Fluctuating asymmetry between left- and right-hand sides was greatest for the lateral incisor. Asymmetry of the mesiodistal dimension of the upper central incisor differed significantly from the buccolingual dimension (p < 0.01). Tooth size in both dimensions was generally larger in boys than in girls. The maxillary lateral incisor displayed significant dimorphism in the mesiodistal dimension (p < 0.05). The second molars (both upper and lower) were less variable and less asymmetrical than the first molars, suggesting that the second molar may be the key tooth of the deciduous molar field.
对来自伦敦的37名男孩、18名女孩和88名性别未知的儿童的近期考古样本中的乳牙尺寸进行了测量。记录了近远中径（接触点处的最大宽度）和颊舌径。尺寸变化梯度明显，前牙的变化最大，第二磨牙的变化最小。总体而言，斯皮塔菲尔德儿童的牙齿比来自各种考古和当代人群的其他群体的牙齿小。侧切牙左右两侧的波动不对称性最大。上颌中切牙近远中径的不对称性与颊舌径有显著差异（p < 0.01）。在两个维度上，男孩的牙齿尺寸通常比女孩的大。上颌侧切牙在近远中径上表现出显著的二态性（p < 0.05）。第二磨牙（上下颌）比第一磨牙的变异性和不对称性更小，这表明第二磨牙可能是乳牙磨牙区的关键牙齿。
