Skeletal Evidence for Leprosy in India by the Second Millenium B.C. [PDF]

, 2009
Leprosy is a chronic infectious disease caused by _Mycobacterium leprae_ that affects almost 500,000 people worldwide^1^. The timing of first infection, geographic origin, and pattern of transmission of the disease are unknown^1-3^.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

VIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

‘Do larger molars and robust jaws in early hominins represent dietary adaptation?’ A New Study in Tooth Wear [PDF]

, 2013
Diet imposes significant constraints on the biology and behaviour of animals. The fossil record suggests that key changes in diet have taken place throughout the course of human evolution.

Feeding Management of African Rhinos (Ceratotherium simum, Diceros bicornis) in European Zoos

Zoo Biology, EarlyView.
The average estimated diets (in % dry matter) of white rhinos (C. simum) and black rhinos (D. bicornis) in European zoos differ in the proportion of (pelleted) compound feed and other non‐forage items. The reason for this difference is elusive but possibly related to creating more complicated diets for browsers. ABSTRACT White rhinos (WR, Ceratotherium

An easy classification for dental cervical abrasions

Dental Hypotheses, 2014
Introduction: Tooth wear - attrition, abrasion, or erosion - are modern day problems for dentistry. It usually leads to discomfort and sensitivity especially during eating, drinking, or tooth brushing.

Relationship between tooth macrowear and jaw morphofunctional traits in representative hypercarnivores

PeerJ
The mammalian adult dentition is a non-renewable resource. Tooth attrition and disease must be accommodated by individuals using behavioral, physiological, and/or musculoskeletal shifts to minimize impact on masticatory performance.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Clinical and self‐reported measurements to be included in the core elements of the World Dental Federation's theoretical framework of oral health

International Dental Journal, EarlyView., 2020
Introduction Oral health is part of general health, and oral diseases share risk factors with several non‐communicable diseases. The World Dental Federation (FDI) has published a theoretical framework illustrating the complex interactions between the core elements of oral health (CEOHs): driving determinants, moderating factors, and general health and ...

Forensic Age Estimation of Chinese Malaysian Adults by Evaluating Occlusal Tooth Wear Using Modified Kim’s Index

International Journal of Dentistry, 2017
Background and Objective. Evaluation of dental attrition is an easy and relatively accurate approach to estimating the age of an adult either ante- or postmortem for some specific population.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.
