“…Bioarchaeological studies often make use of the crown formation charts for European and southern Africans in Reid and coworkers previous work (Holt et al, ; Primeau, Arge, Boyer, & Lynnerup, ; Reid and Dean, ). Given that most LEH studies in bioarchaeology focus on anterior teeth, this study confirms the accuracy of those charts, as the use of southern African initiation times for anterior teeth had little effect on the crown completion times given in Reid and Dean ().…”

This study documents variation in initiation ages, particularly for later-initiating tooth types. It upholds the use of previously published histological aging charts for LEHs on anterior teeth. However, this study finds that ages of crown initiation and completion in second and third molars for this southern African sample are earlier than previously estimated. These earlier ages reduce differences between modern humans and fossil hominins for these developmental events in second and third molars.

“…Through the use of a large sample size (274 teeth from 127 Roman subadults), they concluded that enamel formation patterns are more highly impacted according to the severity of the cause of stress, and that there is no minimum requirement of stress level for enamel to be effected (Fitzgerald & Saunders, 2005). Multiple papers have since been published on this topic, all conclusively stating that stress impacts enamel structures, significantly increases CFTs, and reduces the reliability of DSR calculations (Reid & Dean, 2006;Holt et al, 2012;Birch & Dean, 2014;Primeau et al, 2015). As a result of these studies, we can reliably say that nonaccessory enamel grows differentially in individuals presenting evidence of stress.…”

This study investigates enamel growth of a modern-day human upper first incisor (S197) possessing an accessory cusp. Growth rates collected from the accessory enamel are compared to data collected from the primary cusp and healthy incisors from the same population. Upper first incisors (n=12) and S197 were analysed using histological methods. Daily secretion rates (DSRs) were calculated for inner, mid, and outer regions of cuspal and lateral sites. Additional DSRs were calculated for equivalent regions of S197’s accessory cusp. S197’s primary cusp DSRs were significantly faster than the accessory cusp for all lateral regions, but significantly slower in the inner and mid cuspal regions. S197’s primary cusp DSRs were also significantly faster than the healthy incisor sample for all lateral regions, but significantly slower in the inner and mid cuspal regions. The DSRs of the healthy sample were significantly faster than those of S197’s accessory cusp for all lateral regions, but significantly slower in the inner cuspal region. This case study displays that human teeth possessing accessory cusps can present varying DSRs to healthy teeth of the same population, and that accessory enamel growth may not follow the same pattern of increasing DSRs along the length of enamel prisms.

“…Uma série de elementos fisiológicos, patológicos e nutricionais foi apontada como causas das HLE, entre os quais podem ser citados raquitismo, escorbuto, doenças infecciosas, aspectos nutricionais e processo de desmame (COOK, BUIKSTRA, 1979;HUTCHINSON, LARSEN, 1988;UBELAKER, 1992;WRIGHT, 1997;FISCHER, 2012;PRIMEAU et al, 2015).…”

Porções dentárias muito alteradas por desgaste e cálculo dentário foram desconsideradas da análise e da quantificação, pois prejudicam a visualização e as análises das HLE.…”

A partir de um projeto de pesquisa que objetivou averiguar o comportamento de marcadores osteológicos em remanescentes humanos na perspectiva da longa duração no litoral sul de Santa Catarina, foram obtidos interessantesresultados para o sítio conchífero Içara-01. Foram analisados os marcadores de estresse osteológicos de Hiperostose Porótica (HP), Cribra orbitalia (CO) e Hipoplasia Linear de Esmalte (HLE) em 35 indivíduos de Içara-01 e seusresultados foram comparados com os adquiridos para indivíduos sepultados em períodos concomitantes dos sambaquis Cabeçuda e Jabuticabeira II. As autoras levantam a hipótese de que os indivíduos sepultados em Içara poderiam ser de um grupo litorâneo que utilizou o sítio como cemitério e que teria mobilidade na costa e no planalto, e não provenientes do planalto e que utilizariam Içara comoacampamento temporário, como postula a literatura. Abstract: As part of a research project that aimed to investigate the osteological markers behavior in human remains from a long-term perspective on the south coast ofSanta Catarina (Brazil), interesting results were obtained from the Içara´s conchiferous site (Içara-01). The authors analyzed osteological stress markers of Porotic Hyperostosis (HP), Cribra orbitalia (CO) and Linear Enamel Hypoplasia(LEH) in 35 individuals from Içara-01. They compared the results with those obtained for individuals buried in concomitant periods at Cabeçuda and Jabuticabeira II shellmounds. The hypothesis is that the buried individualsin Içara-01 could be members from a coastal group that used the site as a cemetery and had mobility through the coast and the highland, and not that came from the highland and used Içara-01 as a temporary camp, as the literature postulates.
