The magnitude of fluctuating odontometric asymmetry is reported for a group of 106 urban South African Blacks by use of re-scaled asymmetry values and Euclidean map analyses. When these results were contrasted with those reported for South African Caucasoids and Paraguayan Lengua Indians, Blacks were found to be significantly more asymmetric. It is suggested that the disproportionately high levels of dental asymmetry may be ascribed to the high disease and malnutrition burden of South African Blacks and to decreased individual buffering ability. The present study failed to support Garn's model of x-chromosomal odontogenetic buffering in females, and also failed to confirm significant arcadal differences in the magnitude of fluctuating odontometric asymmetry.
通过使用重新标度的不对称值和欧几里得地图分析，报告了一组106名南非城市黑人的波动性牙量测量不对称程度。当将这些结果与南非白种人和巴拉圭伦瓜印第安人的报告结果进行对比时，发现黑人的不对称程度明显更高。有人认为，牙齿不对称程度过高可能归因于南非黑人的高疾病和营养不良负担以及个体缓冲能力下降。本研究未能支持加恩关于女性X染色体牙齿发生缓冲的模型，也未能证实波动性牙量测量不对称程度存在显著的牙弓差异。
