  • Insights on patterns of developmental disturbances from the analysis of linear enamel hypoplasia in a Neolithic sample from Liguria (northwestern Italy). [Journal Article]
    Int J Paleopathol 2019Orellana-González E, Sparacello VS, … Dori I
  • CONCLUSIONS: LEH may reflect life-history in the local ecology of Neolithic Liguria, where several individuals with osteoarticular tuberculosis have been recorded. Disease burden may have triggered developmental disturbances around the time of weaning. Age at first defect was negatively correlated with age at death and positively with the total number of defects, suggesting that early stress may have affected survivorship.The study contributes to the reconstruction of ecological pressures among Neolithic people of Liguria, and informs on environmental challenges during the Neolithic adaptive expansion.The visual examination of macrophotos is prone to observer error; mid-crown tends to display more visible LEH due to tooth architecture.
  • Safe Casting and Reliable Cusp Reconstruction Assisted by Micro-Computed Tomographic Scans of Fossil Teeth. [Journal Article]
    Anat Rec (Hoboken) 2019; 302(9):1516-1535O'Hara MC, Le Cabec A, … Guatelli-Steinberg D
  • Dental replicas are frequently utilized in paleoanthropological studies of perikymata and enamel hypoplasia. However, fossil teeth are often fragile and worn, causing two problems: (1) the risk of damage by removing enamel fragments when impression-making material is separated from the fossil tooth surface, and (2) the need to reconstruct worn portions of the crown to assess perikymata number, di…
  • Pig enamel revisited - Incremental markings in enamel of wild boars and domestic pigs. [Journal Article]
    J Struct Biol 2019; 205(1):48-59Kierdorf H, Breuer F, … Kierdorf U
  • The nature and periodicity of incremental markings in pig enamel is currently debated. To broaden the basis for a correct interpretation of growth marks in pig enamel, we analyzed their periodicity in teeth of wild boars and domestic pigs. For that, the numbers of enamel incremental markings were recorded in ground sections and compared with crown formation times for the respective teeth derived …
  • Oral Pathology in Forensic Investigation. [Review]
    J Int Soc Prev Community Dent 2018 Jan-Feb; 8(1):1-5Shamim T
  • Forensic odontology is the subdiscipline of dentistry which analyses dental evidence in the interest of justice. Oral pathology is the subdiscipline of dentistry that deals with the pathology affecting the oral and maxillofacial regions. This subdiscipline is utilized for identification through oral and maxillofacial pathologies with associated syndromes, enamel rod patterns, sex determination us…
  • Quantifying linear enamel hypoplasia in Virunga Mountain gorillas and other great apes. [Journal Article]
    Am J Phys Anthropol 2018; 166(2):337-352McGrath K, El-Zaatari S, … McFarlin SC
  • Linear enamel hypoplasia (LEH) is a condition marked by localized reductions in enamel thickness, resulting from growth disruptions during dental development. We use quantitative criteria to characterize the depth of LEH defects and "normal" perikymata in great apes. We test the hypothesis that mountain gorillas have shallow defects compared to other taxa, which may have led to their underestimat…
  • Disturbances and noise: Defining furrow-form enamel hypoplasia. [Historical Article]
    Am J Phys Anthropol 2016; 161(4):744-751Bocaege E, Hillson S
  • The investigation of the record of growth locked in dental enamel provides a unique opportunity to build a comprehensive picture of growth disruption episodes during childhood. This study presents a new methodological basis for the analysis of enamel growth disruptions (enamel hypoplasia) using incremental microstructures of enamel.
  • Lateral enamel growth in human incisors from Çatalhöyük in Turkey. [Historical Article]
    Am J Phys Anthropol 2016; 161(4):656-666Bocaege E, Humphrey LT
  • Whereas the differences in lateral enamel growth between fossil and modern populations have been well documented in recent years, few studies report on the variability in perikymata counts and distribution between modern human populations. There is a need for information on modern human populations from a wide range of geographical regions and archaeological populations to determine whether exist…
