Single or multiple accentuated incremental lines were observed in prenatal enamel of nine teeth and in postnatal enamel of eight teeth. Accentuated Andresen lines and broader zones exhibiting an enhanced calcospheritic pattern were recorded in the pre\u2010 and postnatally formed dentin of nine teeth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>The structural abnormalities in the pre\u2010 and postnatally formed enamel of the infants are considered indicative of chronic stress that negatively affected the activity of secretory ameloblasts. The structural aberrations in pre\u2010 and postnatal dentin denote that odontoblasts were also affected by this stress. The presence of single or multiple accentuated incremental lines in pre\u2010 and postnatal enamel is interpreted as reflecting (short\u2010term) impacts of higher intensity superimposed on the chronic stress. Our findings suggest compromised maternal health affecting the late fetus and compromised health in newborns. Although limited by the small number of analyzed individuals, the present study contributes to the knowledge of maternal and early infant health conditions in Late Epipaleolithic populations.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajpa.24156","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T21:16:02Z","timestamp":1601932562000},"page":"20-34","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Assessment of physiological disturbances during pre\u2010 and early postnatal development based on microscopic analysis of human deciduous teeth from the Late Epipaleolithic site of Shubayqa 1 (Jordan)"],"prefix":"10.1002","volume":"174","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6411-9631","authenticated-orcid":false,"given":"Horst","family":"Kierdorf","sequence":"first","affiliation":[{"name":"Department of Biology University of Hildesheim  Hildesheim Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1663-7618","authenticated-orcid":false,"given":"Carsten","family":"Witzel","sequence":"additional","affiliation":[{"name":"Department of Biology University of Hildesheim  Hildesheim Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emmy","family":"Bocaege","sequence":"additional","affiliation":[{"name":"School of Anthropology and Conservation, University of Kent  Canterbury UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Richter","sequence":"additional","affiliation":[{"name":"Department of Cross\u2010cultural and Regional Studies University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uwe","family":"Kierdorf","sequence":"additional","affiliation":[{"name":"Department of Biology University of Hildesheim  Hildesheim Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,5]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7580.2008.01010.x"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/evan.20239"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1520-6505(1998)6:5<159::AID-EVAN4>3.0.CO;2-7"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4020-8539-0_2"},{"key":"e_1_2_9_6_1","volume-title":"Wadi al\u2010'Ajib\/Shubeiqa Survey 1993.
