Two non-specific indicators of stress: Enamel hypoplasia and Harris lines
Harris lines (HL) and enamel hypoplasia (EH) are two non-specific indicators of stress, commonly used in the reconstruction of the health status in past and present populations. The aim of this study was to determine if there is a correlation between these two markers. To achieve this aim, a sample …

Changes in Suid and Caprine Husbandry Practices Throughout Dynastic Egypt Using Linear Enamel Hypoplasia (LEH)
Linear enamel hypoplasia (LEH) is the most commonly identified form of enamel defect in teeth. Defined as a deficiency in enamel thickness encountered during dental development, LEH can occur as horizontal lines or depressions of irregular enamel, or clusters of pitting on the enamel surface. These …

Enamel hypoplasia in modern and archaeological caprine populations: The development and application of a new methodological approach
… into domestic animals has demonstrated that enamel hypoplasia is a potentially valuable tool for investigating a range of archaeological topics including domestication and animal management strategies. However, research into archaeological domestic populations has been hindered by the …

Putting teeth into the developmental origins hypothesis: A longitudinal study of early childhood malnutrition, enamel hypoplasia and adolescent health in Amazonian Bolivia
… reflect early childhood experience because enamel on the permanent teeth calcifies incrementally during early childhood and is sensitive to physiological stress. Defects in the enamel do not repair after occurrence or during the life course, leaving a permanent biological mark of …

Age-at-Formation and Duration of Linear Enamel Hypoplasia and Accentuated (Pathological) Striae in Ancient, Modern, and Forensic Populations as an Indicator of Differential Developmental Stress
… in age-at-formation and duration of linear enamel hypoplasia (LEH) and accentuated striae (AS) in the mandibular canines of pre-Hispanic Maya individuals from Belize, migrants who died crossing the Texas-Mexico border, and modern American individuals from the Texas State Donated Skeletal …

Dental defects and rubella embryopathy: a clinical study of fifty children
… Of the rubella children studied, 90 per cent had enamel hypoplasia, 78 per cent had tapered teeth, and 18 per cent had notched anterior teeth. Among the normal children studied, 26 per cent had enamel hypoplasia, 18 per cent had tapered teeth, and none had notched teeth. No other dentofacial …

Pastoralism, Agriculture, and Stress: A Comparative Analysis of Two 19th Century Qing Dynasty Populations
… hyperostosis, cribra orbitalia, and linear enamel hypoplasia were assessed macroscopically. Results show that in all pathological conditions except cribra orbitalia, stress indicators were significantly more frequent in the agriculturalist Karluk sample than in the pastoralist Urga sample; …

Dental pathology, wear and developmental defects in South African hominins
… Variables recorded include antemortem chipping, enamel hypoplasia, caries, occlusal wear, tertiary dentine, abscesses, and periodontal disease. Clear differences in frequencies were found in the different South African hominin species. Homo naledi displays high rates of chipping, especially small …

A comparative analysis of human skeletal remains from Parowan Fremont, Virgin Anasazi, and Kayenta Anasazi archaeological sites
… prevalence of periostitis, osteitis, and linear enamel hypoplasia was found to be highest among Virgin Anasazi individuals. Two other pathologies, porotic hyperostosis and cribra orbitalia, were most common among the Kayenta sample and least among the Parowan Fremont sample; From literature …

Exploring a Biocultural Model of Resiliency in the lower Illinois River Valley from Middle to Late Woodland Periods
… for the nonspecific stress indicators of linear enamel hypoplasia, tibial periostosis, and changes to average stature. Both adult and non-adult Middle and Late Woodland burial contexts from the Elizabeth site were also examined in terms of burial posture and grave good inclusion. Meaningful …

Nutrition at Tipu: A Comparative Analysis of Juvenile Health in Maya Populations
… juvenile health through four markers: Linear Enamel Hypoplasia (LEH), a non-specific marker of health disruptions; Porotic Hyperostosis (PH), an indicator of anemia; and Periostitis, an indicator of infection. Some 131 individuals were evaluated using criteria developed by Steckel, Sciulli, …

Plague mortality and medieval demography: an osteological analysis of Black Death mass graves and attritional cemeteries from 7-16th century England and Wales
… Those aged 15-24 years, and those with linear enamel hypoplasia present, were substantially over-represented within the mass graves — suggesting these groups were particularly vulnerable to plague mortality. Socioeconomic and environmental factors may have increased their mortality risk. …

Bringing Childhood Health into Focus: Incorporating Survivors into Standard Methods of Investigation
… Long bone and vertebral canal growth, linear enamel hypoplasia, cribra orbitalia, porotic hyperostosis, scurvy indicators and periosteal bone reactions were assessed for both groups. Overall, long bone growth generates the same interpretation of health for both non-survivors and survivors, and …

Stress Along the Medieval Anglo-Scottish Border? Skeletal Indicators of Conflict-Zone Health
… available non-adults along with higher rates of enamel hypoplasia in the young adults. These contradictory results call into question both the documentary evidence regarding the longevity and severity of medieval border warfare and the sensitivity of osteological data to health changes associated …

A multidisciplinary approach to reconstruct the lived-experience of people with ‘leprosy’ and Hansen’s Disease in medieval England
… of this study show that poor childhood health (enamel hypoplasia, short stature, cribra orbitalia, low dietary isotope values) increases the likelihood of (severe) HD infection in later life. Both (severe) HD infection and poor childhood health make it more likely that individuals are provided …

Dental pathology and macrowear: a biocultural analysis of southern African holocene hunter-gatherers and hunter-herders
… improvements. Notably, incidence rates for enamel hypoplasia on the first molars (n = 26) alluded to increased infant stress possibly related to herding. Interestingly, amelogenesis imperfecta was found, demonstrating a hereditary condition associated with comorbidities. Despite increasing …
