Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Changes in Suid and Caprine Husbandry Practices Throughout Dynastic Egypt Using Linear Enamel Hypoplasia (LEH) [PDF]

, 2011
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 ...

Associations between enamel defects and caries in patients with Down syndrome compared with normotypic patients [PDF]

Brazilian Oral Research
This study aimed to explore the prevalence of developmental defects of enamel (DDE) and dental caries in children with and without Down syndrome (DS) and evaluate potential associations between these conditions.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Risk Factors of Developmental Defects of Enamel-A Prospective Cohort Study

PLoS ONE, 2014
Current studies on the aetiology of developmental defects of enamel (DDE) are subject to recall bias because of the retrospective collection of information. Our objective was to investigate potential risk factors associated with the occurrence of DDE through a prospective cohort study.Using a random community sample of Hong Kong children born in 1997 ...

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

Journal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

Diagnosis of developmental defects of enamel made from photographs

, 2011
Photographs offer an opportunity to remotely examine teeth for developmental defects of enamel. However, the flash on the camera can cause burn-out which obscures the surface. Therefore, multiple views may be necessary to overcome this problem.

Assessing the Impact of Diet on Enamel Hypoplasia in Children

Journal of Pharmacy and Bioallied Sciences
Background: Enamel hypoplasia is a developmental defect of enamel characterized by incomplete or defective enamel formation. It is often influenced by genetic, systemic, and environmental factors, including diet.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it
