Dental caries in human evolution: frequency of carious lesions in South African fossil hominins
Caries frequency typically ranges between 1-5% of teeth in non-agricultural human samples, and this pattern seemingly holds true for at least the past two million years in the hominin lineage.
Dental caries in South African fossil hominins
The results suggest cariogenic biofilms and foods may have been present in the oral environment of a wide variety of hominins, including five Paranthropus robustus, one early Homo, and one Homo naledi.
Tooth chipping patterns in Paranthropus do not support regular hard food mastication
Comparative chipping analysis suggests that both Paranthropus species were unlikely habitual hard object eaters, at least compared to living durophage analogues.
Dental caries in wild primates: Interproximal cavities on anterior teeth
Given the presence of ICATs in frugivorous primates, their diagnosis in archaeological and paleontological specimens may shed light on diet and food processing behaviors in fossil primates.
Dental caries in wild primates: interproximal cavities on anterior teeth
Given the constancy of ICAT’s in frugivorous primates, their presence in archaeological and paleontological specimens may shed light on diet and food processing behaviors in fossil primates.
Heterogeneous frailty and the expression of linear enamel hypoplasia in a genealogical population.
This study provides evidence for familial risk of LEH (genetic and environmental) that has consequences for the broad use of this skeletal marker of stress in archaeological assemblages, population health studies, where genetic relatives and household groups might be heavily represented.
The Effect of Missense Mutation of FAM20A on Dental Development and Mineralization
A novel homozygous deletion mutation in exon 11 of FAM20A has been described in five members from a large consanguineous Bedouin family, all five with hypoplastic-hypocalcified AI and unerupted and crown resorbed permanent molars, a very rare phenotype.
Paleoecology of the Rhinocerotidae (Mammalia, Perissodactyla) from Béon 1, Montréal-du-Gers (late early Miocene, SW France): Insights from dental microwear texture analysis, mesowear, and enamel hypoplasia
The late early Miocene Béon 1 locality has yielded an abundant vertebrate fauna with more than 5,000 remains assigned to four rhinocerotid species: the stem rhinocerotine Plesiaceratherium mirallesi,


Dental pathology, wear and developmental defects in South African hominins
A substantial difference in frequencies of the different variables among hominin species is supported, supporting the proposition that their diets differed substantially.
Gross enamel hypoplasia in molars from subadults in a 16th-18th century London graveyard.
Dental Enamel Hypoplasia has long been used as a common nonspecific stress indicator in teeth from archaeological samples. Most researchers report relatively minor linear and pitted hypoplastic
Enamel hypoplasias and physiological stress in the Sima de los Huesos Middle Pleistocene hominins.
The majority of LEH in the SH sample occurred during the third year of life and may be related to the metabolic stress associated with weaning, and the most likely explanation for the relatively low LEH and PFD prevalence suggests that the SH population exhibited a low level of developmental stress.

Results from all three study collections reveal that among the great apes, gorillas (87-92%) and orangutans (91%) have a significantly higher prevalence of canine enamel defects than chimpanzees (22-48%).

The present investigation represents an exploratory histologic survey of the developmental quality of human teeth originating from earlier periods of time and various parts of the world; namely, Paleolithic Palestine, prehistoric Greece, predynastic Egypt, ancient Iceland, and middle age Norway from the old world, and Guatemalan and Pecos Indian teeth from the new world.
Hereditary Enamel Hypoplasia in a Prehistoric Indian Child
This work has found the first prehistoric example of amelogenesis imnperfecta in a skeleton from the Schiild Cemetery, Greene County, Illinois, which is probable that an adult with such caries-prone teeth would have become edentulous at an early age.
Chronology of Linear Enamel Hypoplasia Formation in the Krapina Neanderthals
During childhood, systemic physiological stresses such as illness, disease, and malnutrition can disrupt the growth of dental enamel. These disruptions are often recorded in the form of linear enamel
Incidence and patterning of dental enamel hypoplasia among the Neandertals.
The paucity of deciduous tooth DEH and M1 DEH, combined with generally increasing levels of DEH through later calcifying teeth, suggests that the stress was primarily nutritional, beginning at weaning and continuing through adolescence, implying significantly lower effectiveness for Neandertal foraging compared to that of modern humans.
