“…Juveniles from Santa Catalina de Guale had a higher frequency of enamel defects than adults, but the difference between juveniles and adults was not significant (Simpson et al, 1990). Cucina (2002) examined LEH in the mandibular canines from 11 Italian sites, but observed significantly higher frequencies of LEH in subadults (under 20 years) than adults in only two of the samples examined. Malville (1997) found no significant differences between adults and subadults in the timing of hypoplasias or in the percentages of teeth and individuals affected in ancestral Puebloan populations from southwestern Colorado.…”

Enamel hypoplasias are useful indicators of systemic growth disturbances during childhood, and are routinely used to investigate patterns of morbidity and mortality in past populations. This study examined the pattern of linear enamel hypoplasias in two different burial populations from 18th and 19th Century church crypts in London. Linear enamel hypoplasias on the permanent dentitions of individuals from the crypt of Christ Church, Spitalfields, were compared to enamel defects on the teeth of individuals from St. Bride's. The method used involves the identification of enamel defects at a microscopic level, and systemic perturbations are detected by matching hypoplasias among different tooth classes within each individual. The pattern of linear enamel hypoplasias was contrasted between individuals from the burial sites of Spitalfields and St. Bride's, between males and females, and between those aged less than 20 years of age and those aged over 20 years at death. Six different parameters were examined: frequency of linear enamel hypoplasias, interval between defects, duration of hypoplasias, age at first occurrence of hypoplasia, age at last occurrence of hypoplasia, and the percentage of enamel formation time taken up by growth disturbances. All individuals in the study displayed linear enamel hypoplasias, with up to 33% of total visible enamel formation time affected by growth disruptions. Multiple regression analysis indicated a number of significant differences in the pattern of enamel hypoplasias. Individuals from Spitalfields had shorter intervals between defects and greater percentages of enamel formation time affected by growth disturbances than did individuals from St. Bride's. Females had greater numbers of linear enamel hypoplasias, shorter intervals between defects, and greater percentages of enamel formation time affected by growth disturbances than males. There were also differences in the pattern of enamel hypoplasias and age at death in this study. Individuals who died younger in life had an earlier age at first occurrence of enamel hypoplasia than those who survived to an older age. The pattern of enamel hypoplasias detected in this study was influenced by tooth crown geometry and tooth wear such that most defects were found in the midcrown and cervical regions of the teeth, and greater numbers of defects were identified on the anterior teeth. Differences in sensitivity of the parameters used for the detection of enamel hypoplasias were found in this study. The percentage of visible enamel formation time affected by growth disturbances was the parameter that identified the greatest number of significant differences among the subgroups examined.

“…For example, some studies investigated the chronological changes in patterns of LEH occurrence in a certain population, often associated with changes in subsistence (e.g. Rose et al, 1978;Rudney, 1983;Cucina, 2002;Griffin & Donlon, 2007;Starling & Stock, 2007) or contacts with another population (Santos & Coimbra, 1999;Littleton, 2005).…”

Linear enamel hypoplasia (LEH) has been utilised in human bioarchaeology as an indicator of growth disturbance during childhood. However, only a few studies have compared populations of different socio‐economic status in the same time period. This study examines the association between the LEH occurrence pattern and social status in the 18th to 19th century populations in Japan. Detailed archaeological studies on burials from the Edo period (1603–1867) excavated in Tokyo have facilitated estimating an individual's social status by its burial type. In this study, 112 individuals from the Sugenji‐Shokenji site were divided into three burial structure groups (ceramic jar coffins for middle‐class warriors, wooden square coffins for low‐class warriors and townspeople and wooden circular coffins for townspeople) and examined for the general prevalence of LEH, number of LEH and the chronological distribution of LEH. A high general prevalence of LEH was observed in every group, especially in lower canine (79.3–100.0%). However, individuals in the jar coffin group showed a lower prevalence and smaller number of LEH per tooth, suggesting that individuals of higher social status experienced better living environments in their childhood. There was no significant difference in the chronological distribution of LEH formation between coffin groups. Such data are essential for understanding the association between socio‐economic status and living conditions in specific societies in the past. Copyright © 2015 John Wiley & Sons, Ltd.

“…1). As the most common type of hypoplastic defect (Hillson and Bond, 1997), LEH has long been and continues to be employed as an indicator of physiological stress in the fields of bioarcheology (e.g., Goodman et al, 1980;Cohen and Armelagos, 1984;Corruccini et al, 1985;Lukacs, 1992;Cucina and Iscan, 1997;Cucina, 2002;Klaus and Tam, 2009) and human biology (e.g., Sweeney et al, 1971;Enwonu, 1973;Goodman et al, 1991Goodman et al, , 1992Zhou and Corruccini, 1998;Littleton and Townsend, 2005). A recent study linking nutritional deficiency in the Cayo Santiago rhesus monkey colony to elevated LEH prevalence (Guatelli-Steinberg and Benderlioglu, 2006) suggests that, as in humans, physiological stress in nonhuman primates is associated with LEH.…”

Physiological stress, such as malnutrition or illness, can disrupt normal enamel growth, resulting in linear enamel hypoplasias (LEHs). Although ecological factors may contribute to LEH expression, other factors, such as surface abrasion and enamel growth variables, are also likely to be involved. Attention to these other factors is necessary before we can begin to understand what LEH might signify in terms of ecological sources of physiological stress in non-human primates. This study focuses on assessing the contribution of these other factors to variation in LEH expression within and across great ape taxa. Here, we present LEH data from unabraded crown regions in samples of seven great ape species. We analyze these data with respect to lateral enamel formation time and the angles that striae of Retzius make with the enamel surface, as these variables are expected to affect variation in LEH expression. We find that although the duration of enamel formation is associated with sex differences in LEH expression, it is not clearly related to taxonomic variation in LEH expression, and does not explain the low frequency of LEH in mountain gorillas found in this and a previous study. Our data on striae of Retzius angles suggest that these influence LEH expression along the tooth crown and may contribute to the consistently high frequencies of LEH seen in Pongo in this and previous studies. We suggest that future work aimed at understanding species variation in these angles is crucial to evaluating taxonomic patterns of LEH expression in great apes.
