We examined the prevalence and developmental timing of linear enamel hypoplasias (LEHs) in an early Archaic Floridian population from Windover (8,120-6,980 (14)C years B.P. uncorrected). Using digital images, mandibular and maxillary canines were analyzed for defect prevalence and timing of insults. Although overall prevalence was very weakly correlated with earlier defect timing, there were significant differences in defect prevalence that varied by sex and tooth type. The mean LEH count in male mandibular canines was far higher than in male maxillary canines or in female mandibular or maxillary canines. We examined defect timing as a possible predictor of the sex differences in LEH prevalence. There were no significant sex differences in the developmental timing of the earliest defects in either tooth class. Developmental timing is not responsible for the sex differences seen in defect prevalence in mandibular canines.
我们研究了佛罗里达州温多弗一处早期古风时期人群(未经校正的碳-14年代为公元前8120 - 6980年)线性釉质发育不全(LEH)的患病率及发育时间。利用数字图像,分析了下颌和上颌犬齿的缺损患病率及损伤时间。尽管总体患病率与早期缺损时间的相关性非常弱,但缺损患病率存在显著差异,且因性别和牙齿类型而异。男性下颌犬齿的平均LEH计数远高于男性上颌犬齿或女性下颌及上颌犬齿。我们将缺损时间作为LEH患病率性别差异的一个可能预测因素进行了研究。在这两类牙齿中,最早缺损的发育时间均不存在显著的性别差异。发育时间并非导致下颌犬齿缺损患病率性别差异的原因。
