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 ...

Tooth Enamel Hypoplasia in PHACE Syndrome
, 2014 Individuals with PHACE syndrome (posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye abnormalities, sternal cleft, and supraumbilical raphe syndrome) have reported dental abnormalities to their healthcare providers and in

Intraspecific variation in M1 enamel development in modern humans: implications for human evolution [PDF]
, 2008 The timing and sequence of enamel development, as well as enamel thickness, was documented for individual cusps (protoconid, hypoconid,metaconid, entoconid) in 15 unworn permanent lower first molars (M1s) from a sample of modern human juveniles.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Archaeometry, EarlyView.ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Lipopolysaccharide (LPS) introduction during growth and development period of rat’s tooth toward the occurrence of enamel hypoplasia [PDF]
, 2007 The aim of this study is to know the effect of lipopoly saccharide (LPS) induction during growth and development period specifically the occurrence of hypoplasia on tooth enamel. 5 day old male wistar rats divided into two groups. Group 1 (control) under

Boreas, EarlyView.This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Enamel Hypoplasia Related to Historical Famine Stress in the Contemporary Chinese Population
Dental Anthropology, 1997 Linear enamel hypoplasia (LEH), a defect in enamel formation, has been frequently attributed to malnutrition and other physiological stress during periods of enamel development (Sarnat and Schour, 1941; Kreshover, 1960).
