Mineral content and distribution of fluorosed and unfluorosed (control) dental enamel of roe deer and red deer cheek teeth were analyzed using digital backscattered electron (BSE) imaging of PMMA-embedded specimens. Compared to the controls, the fluorosed enamel exhibited various aberrations resulting from a fluoride-induced disturbance of the ...

Correlates of enamel hypoplasia with human dental reduction
American Journal of Human Biology, 1990AbstractHuman dental reduction has been manifested in evolutionary and secular trends, but it is not known to what degree each of these complementary processes contributes to changes in tooth size. Enamel hypoplasia is a marker of developmental stress that is often found to be of greater frequency and severity in populations undergoing dental size ...

The prevalence of dental caries, enamel opacities and enamel hypoplasia in Ugandans
Archives of Oral Biology, 1972Abstract An epidemiological survey on the prevalence of dental caries, enamel opacities and enamel hypoplasia was conducted on 1399 persons in four districts in Uganda with fluoride in the drinking water varying from 0.11 to 3.00 ppm. The dental caries experience was found to be very low (0.0–0.9 DMF-T per person in the 5–9 yr age group and 0.4–2.8 ...

Incidence and patterning of dental enamel hypoplasia among the Neandertals
American Journal of Physical Anthropology, 1989AbstractDental enamel hypoplasia (DEH), as an indicator of nonspecific stress during development, provides an assessment of the relative morbidity of past human populations. An investigation of 669 Neandertal dental crowns yielded an overall DEH frequency of 36.0% by tooth (41.9% for permanent teeth; 3.9% for deciduous teeth) and about 75% by ...

Dental Enamel Hypoplasias in Prehistoric Populations
Advances in Dental Research, 1989Recent years have witnessed an impressive increase in research on enamel hypoplasias in archaeological populations. By reviewing a series of studies of enamel hypoplasias at Dickson Mounds, Illinois, North America (950-1300 A.D.), a prehistoric site involved in the transition from gathering-hunting to agriculture, this paper provides an illustration of

Ultrastructure of Dental Enamel afflicted with Hypoplasia: An Atomic Force Microscopic Study
Calcified Tissue International, 2004The ultrastructure of the human tooth enamel from a patient diagnosed with hypoplasia (HYP) was investigated using atomic force microscopy (AFM) and compared with the surface of normal human tooth enamel. Hypoplasia is a hereditary defect of dental enamel in which the enamel is deficient in either quality or quantity.

A laboratory assessment of enamel hypoplasia of teeth with varying severities of dental fluorosis
Journal of Oral Rehabilitation, 1999The effect of lifelong exposure to drinking‐water containing fluoride on tooth enamel microhardness was investigated. Dental fluorosis of teeth from adult subjects, who lived continuously since birth in areas characterized by the hot climate of India, supplied by drinking‐water containing between 0·5 and 8·7 parts/10 F, was estimated by the Dean score.

Enlarged dental follicles, a follicular cyst, and enamel hypoplasia in a patient with Lowe syndrome
Oral Surgery, Oral Medicine, Oral Pathology, 1994Abstract An 11 ½-year-old body with Lowe syndrome presented with various dental abnormalities including delayed eruption, enamel hypoplasia, and enlarged follicles surrounding unerupted teeth.

[Dental enamel hypoplasia apropos of a case].
Fogorvosi szemle, 1996The developmental anomalies of dental hard tissues are relatively common in children. These anomalies can involve separately the enamel and they are due to many factors acting during odontogenesis. The paper deals with the main ethological factors and describes a case of idiopathic hypercalcemia.
