Incidence and patterning of dental enamel hypoplasia among the Neandertals
American Journal of Physical Anthropology, 1989 AbstractDental 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 ...

Prevalence and possible etiology of dental enamel hypoplasia
American Journal of Physical Anthropology, 1978AbstractTwo hundred black and white adult human skeletons and 200 living black and white children from the greater Cleveland area were examined for evidence of enamel hypoplasia. Enamel hypoplasia, present in varying expressions (pits, lines and grooves), was found to be more prevalent in both skeletal samples, than in the living groups.

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 ...

Hypoplastic area method for analyzing dental enamel hypoplasia
American Journal of Physical Anthropology, 1995AbstractMost analyses of dental enamel hypoplasia compare frequencies of disturbed tooth types, which do not account for variability in the area of affected enamel. An alternate methodology, hypoplastic area, is presented here that accounts for this variability by combining acute and continuous enamel hypoplasia into an interval‐level variable.

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 ...

Pediatric dentistry, 1997 This longitudinal study investigated the sequelae of enamel defects in a group of 25 white, very-low birthweight (VLBW), preterm children (mean birthweight 969 +/- 218 g, mean gestational age 27 +/- 1.9 weeks). Twenty-five race-, age-, and sex-matched, full-term normal birthweight (NBW) control children born at the same hospital, were selected randomly

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 ...

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.
