Teeth are an interesting material for the study of ancient populations. The aim of our study was to determine the prevalence and distribution of caries in a medieval sample of paired maxillas in a rural population in Southwest France and to compare men and women.
Our sample included 58 adults, 29 men and 29 women, with dentate maxillas in good state of conservation, for a total of 1,395 teeth out of a possible 1,846 (75%). The number of caries and their localization were noted.
The frequency of antemortem missing teeth was 8.67%. The prevalence of caries was 17.46% and the most frequent caries were occlusal and proximal. Second and third molars were the most frequently affected maxillary and mandibular teeth. Caries on maxillary teeth were statistically more frequent than on mandibular teeth (p<0.05). There was no significant difference between men and women (p>0.05).
Our study showed that the frequency and the distribution of dental caries in this medieval population from southwest France were comparable to those of other European populations from the same period. The low level of caries was probably due to attrition and noncariogenic food. Differences between men and women were not significant, even though our results suggest that men were much more concerned by caries than women, especially for posterior teeth. A different diet may be the reason for this difference.
牙齿是研究古代人群的一种有趣材料。我们研究的目的是确定法国西南部农村人口中世纪成对上颌骨样本中龋齿的患病率和分布情况，并比较男性和女性。
我们的样本包括58名成年人，29名男性和29名女性，其保存完好的有牙上颌骨，在可能的1846颗牙齿中共有1395颗（75%）。记录了龋齿的数量及其位置。
生前缺失牙的频率为8.67%。龋齿患病率为17.46%，最常见的龋齿是咬合面和邻面的。第二和第三磨牙是上颌和下颌中最常受影响的牙齿。上颌牙齿的龋齿在统计学上比下颌牙齿更常见（p<0.05）。男性和女性之间没有显著差异（p>0.05）。
我们的研究表明，法国西南部这个中世纪人群中龋齿的频率和分布与同期其他欧洲人群相当。龋齿水平较低可能是由于磨损和非致龋性食物。男性和女性之间的差异不显著，尽管我们的结果表明男性比女性更易患龋齿，尤其是后牙。不同的饮食可能是造成这种差异的原因。
