The purpose of this study was to determine whether children from Early Bronze Age and modern populations differ in terms of the width of the neonatal line (NNL) and the occurrence of accentuated lines in enamel.
The sample (N = 59) consisted of two groups: 29 deciduous teeth removed from the jaws of children (dental age range from 1 to 10 years) whose skeletal remains were found in Early Bronze archaeological graves in Mokrin Serbia, and 30 present-day exfoliated deciduous teeth from 6 to 11 year old children. Mothers, whose children participated in this study, provided information regarding their health during pregnancy. The analysis was carried out on ground sections with a scanning electron microscope. Two clinicians measured the width of the NNL and counted the accentuated lines in the enamel.
There was a statistically significant difference between the children from the two groups regarding the width of the NNL. The width of the NNL between children whose mothers were healthy and diagnosed with gestational diabetes was significantly different. Most subjects did not have accentuated lines in the prenatal enamel, regardless of whether they were from the Bronze or Modern age. Accentuated lines were dominantly found in the postnatal enamel of the children from the Early Bronze age.
This study is the first to investigate the width of the NNL in teeth of Maros children and Serbian children from the modern age. The wider NNL of children from the Early Bronze age indicates the possibility that they have experienced more overall stress in perinatal life.
本研究旨在确定青铜时代早期儿童与现代儿童在新生儿线（NNL）宽度及牙釉质中明显纹路的出现情况方面是否存在差异。
样本（N = 59）由两组组成：29颗从塞尔维亚莫克林青铜时代早期考古墓葬中发现的儿童颌骨（牙龄范围为1至10岁）上拔除的乳牙，以及30颗来自6至11岁现代儿童的脱落乳牙。参与本研究的儿童的母亲提供了她们孕期健康状况的信息。使用扫描电子显微镜对磨片进行分析。两名临床医生测量了NNL的宽度并计数牙釉质中的明显纹路。
两组儿童在NNL宽度方面存在统计学上的显著差异。母亲健康与被诊断为妊娠期糖尿病的儿童之间的NNL宽度存在显著差异。无论来自青铜时代还是现代，大多数受试者的产前牙釉质中都没有明显纹路。明显纹路主要出现在青铜时代早期儿童的产后牙釉质中。
本研究首次调查了马罗斯儿童和现代塞尔维亚儿童牙齿中NNL的宽度。青铜时代早期儿童较宽的NNL表明他们在围产期生活中可能经历了更多的总体压力。
