e·nam·el hy·po·pla·si·a

a developmental disturbance of teeth characterized by deficient or defective enamel matrix formation; may be hereditary, as in amelogenesis imperfecta, or acquired, as encountered in dental fluorosis, local infection, childhood fevers, and congenital syphilis.

Finally, an association was detected between clinical sequelae in permanent teeth and time elapsed post-trauma, that is, children evaluated for a period of 24-35 months showed a higher prevalence of sequelae, such as enamel hypoplasia.
Enamel is the hardest tissue of body and marks of enamel hypoplasia (EH) remain unaltered even during fossilization so it can be a highly admirable stress marker for the life history of an extinct animal.
However, we found no correlation between bruxism and possible signs of immunological disease such as recurrent aphthous stomatitis and enamel hypoplasia.
* Additional unusual dental findings such as single-rooted funnel-shaped molars, reduced crown size, enamel hypoplasia, supernumerary teeth, dental fusion, dysmorphic roots, taurodontism, abnormal occlusal anatomy with wide grooves, and atypical cusps have been reported in most previous cases of the Ellis-van Creveld syndrome.
(5) Since the etiology of DED include genetic and environmental factors, localities characterized by economic deprivation and environmental variations should be taken into account to measure enamel defects such as fluoride opacities and enamel hypoplasia.

The frequency of cribra orbitalia, dental enamel hypoplasia, and new bone formation was recorded in the St.
The well-recognized and historically documented example of chemically induced enamel hypoplasia refers to the effects of chronic fluoride toxicity on the dentition, and although total fluoride intake will vary with total water consumption, fluoride-induced enamel hypoplasia, also referred to as fluoride mottling, is usually inconspicuous at levels below 1.0 ppm in the drinking water.
The population suffered from trauma (scalping and blows to the head), infections (including tuberculosis), early onset osteoporosis among males as well as females, anemia, vitamin deficiencies (including scurvy and rickets), and linear enamel hypoplasia (LEH, tooth enamel development disrupted by a stress event during childhood after age 2).
So, to add another level of analytical evidence, a strong emphasis is placed on the technique of identifying growth defects in the enamel of the developing molar teeth known as Linear Enamel Hypoplasia (LEH).
Dental observations were also recorded; caries, abscesses, antemortem tooth loss, and enamel hypoplasia provide direct evidence for nutrition and health (Cohen and Armelagos 1984; Hillson 1996).
