A roughly circular hypoplastic defect restricted to the labial enamel surface of the deciduous canine is described. This pathology is quite common in available samples of Upper Paleolithic and Neolithic children and a cadaver sample of recent Calcuttans, affecting 44% to 70% of individuals. It is rare in a Neanderthal sample and in children from a clinical practice in Vancouver. The lesion occurs twice as commonly in the lower jaw. The defect appears to commence at or after birth owing to…

Enamel hypoplasia in the deciduous teeth of early Miocene catarrhines: evidence of perinatal physiological stress.
  • J. Lukacs
  • Medicine
    Journal of human evolution
  • 2001
TLDR
An approximately 17-23 Ma antiquity for EH among early catarrhines is established and it is suggested that the neonatal stage of ontogenetic development was sufficiently stressful physiologically to produce disruption in amelogenesis.
Prevalence of an unusual hypoplastic defect of the permanent maxillary lateral incisor in great apes
TLDR
This defect of the maxillary lateral incisor is the second most common defect I observed in the study sample, and was more likely to occur in individuals with linear enamel hypoplasia (LEH) and pit defects than those without these defects.
HIGH PREVALENCE OF ENAMEL HYPOPLASIA IN AN EARLY PLIOCENE GIRAFFID (SIVATHERIUM HENDEYI) FROM SOUTH AFRICA
TLDR
It is proposed that poor environmental conditions, possibly seasonal nutritional stress, are responsible for the observed enamel hypoplasia in the permanent dentition of S. hendeyi.
Developing a pig model for crypt fenestration-induced localized hypoplastic enamel defects in humans.
TLDR
It is concluded that a pig model is appropriate to study fenestration-induced enamel defects, and whether osteopenia in pigs, and by extension in human infants, is due to disease and/or malnutrition is left unresolved.
Interproximal contact hypoplasia in primary teeth: A new enamel defect with anthropological and clinical relevance
  • J. Lukacs
  • Medicine
    American journal of human biology : the official journal of the Human Biology Council
  • 1999
TLDR
Prevalence of interproximal contact hypoplasia (IPCH) is reported from a prehistoric site in western India, where IPCH prevalence decreases across the subsistence transition from sedentary Early Jorwe agriculturalists to seminomadic LateJorwe hunters and foragers, but the difference is not statistically significant.
Social and biological correlates of localized enamel hypoplasia of the human deciduous canine tooth.
TLDR
The defect appears to be due to minor physical trauma to the face approximately 6 months after birth occasioned by normal motor development, involving handling and mouthing objects, which damages the developing tooth crown through deficient cortical bone over the canine crypt.
An Enigmatic Hypoplastic Defect of the Maxillary Lateral Incisor in Recent and Fossil Orangutans from Sumatra (Pongo abelii) and Borneo (Pongo pygmaeus)
TLDR
It is concluded that maxillary lateral incisor defect is a common developmental pathology of apes that is minimized in optimal habitats and that such evidence can be used to infer habitat quality in extant and fossil apes.
Localised enamel hypoplasia of human deciduous canines: genotype or environment?
TLDR
The results confirm some of the findings of previous studies, but also suggest that none of environmental, genetic or systemic factors can be ruled out as being involved in aetiology of the defect.
Prevalence and racial distribution of primary canine hypoplasia of the maxillary canine.
TLDR
Prevalence data is provided for PCH affecting the maxillary primary canines in different age, gender, and race cohorts and a significant relationship also was demonstrated between PCH and dental caries.
Primary canine hypoplasia in Head Start children.
TLDR
Preliminary data indicate that the presence of primary canine hypoplasia may result in an increased potential for the tooth becoming carious.

TLDR
The buccal and lingual roots of 1077 teeth from 100 mandibles of South African Negroes were examined for the presence of dehiscences and fenestrae and defects were found exclusively in the buCCal plate of the alveolar process.

TLDR
Relationships suggest that at least moderate levels of malnutrition existed in Illinois Woodland populations, with a significant association between prenatal dental defects and bony evidence for anemia and infectious disease.

  • M. Wolpoff
  • Medicine

TLDR
The Krapina dental sample fits in a European evolutionary sequence of reducing posterior and expanding anterior permanent teeth, while the deciduous teeth seem to undergo expansion through the Würm glaciation.
Prevalence and possible etiology of dental enamel hypoplasia.
TLDR
The reduction in the prevalence of enamel hypoplasia in the groups examined through time may be related to improved nutritional conditions and the elimination or decline of childhood diseases that have been implicated in this condition.

TLDR
It is demonstrated that the criteria of abnormal prism structure can accurately differentiate defective enamel from normal enamel, and that pathological bands can be divided into three distinct subtypes: distorted structure bands, black spot pathological bands, and structureless pathological bands.
The chronological distribution of enamel hypoplasias from prehistoric Dickson Mounds populations.
TLDR
The chronological distributions of enamel hypoplasias (indicators of nonspecific stress) are assessed for 111 individuals from two prehistoric populations from Dickson Mounds, Lewiston, Illinois to demonstrate that populations may vary in their chronological distribution of hypoplasia and that these variations may provide useful information on age-related patterns of exposure to environmental stressors.
