Digital analysis of tooth microwear, a potential application for dental microwear monitor [PDF]

Biosurface and Biotribology, 2022
In general, tooth wear is difficult to be noticed until it leads to toothache in vivo. Developing a dynamic dental wear monitoring system to predict tooth wear in daily life is a necessity.

Dental microwear texture analysis along reptile tooth rows: complex variation with non-dietary variables [PDF]

Royal Society Open Science, 2021
Dental microwear texture analysis (DMTA) is a powerful technique for reconstructing the diets of extant and extinct taxa. Few studies have investigated intraspecific microwear differences along with tooth rows and the influence of endogenous non-dietary ...

Diet reduces the effect of exogenous grit on tooth microwear [PDF]

Biosurface and Biotribology, 2020
Exogenous grit adherent to the surface of food items and food fracture properties have each been considered important factors contributing to pattern and degree of tooth wear in mammals.

Similar associations of tooth microwear and morphology indicate similar diet across marsupial and placental mammals. [PDF]

PLoS ONE, 2014
Low-magnification microwear techniques have been used effectively to infer diets within many unrelated mammalian orders, but the extent to which patterns are comparable among such different groups, including long extinct mammal lineages, is unknown ...

Tooth microwear texture in odontocete whales: variation with tooth characteristics and implications for dietary analysis

Biosurface and Biotribology, 2017
Understanding the diets and trophic relationships of toothed whales is central to understanding their roles in marine ecosystems, and associated conservation issues.

Dental Microwear Texture Analysis of the Bornean Orangutans (Pongo pygmaeus) From the Selenka Collection. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Characterizing the diet of extant taxa is important not only to determine their ecological niche but also to serve as a reference for dietary and niche inferences in evolutionary studies. Tracking the diets of fossil taxa and their change through time has been increasingly employed to further understand the evolution of primates. In

Climate Change Challenges Grey Wolf Resilience: Insights From Dental Microwear. [PDF]

Ecol Lett
We investigate dietary plasticity in European grey wolves across interglacial periods using dental microwear texture analysis. Enhanced durophagy is associated with warm climates in both modern Polish and British Pleistocene wolves, indicating deep‐time behavioural flexibility.

Multi-proxy dentition analyses reveal niche partitioning between sympatric herbivorous dinosaurs [PDF]

Scientific Reports, 2022
Dentitions of the sympatric herbivorous dinosaurs Hungarosaurus (Ankylosauria, Nodosauridae) and Mochlodon (Ornithopoda, Rhabdodontidae) (Santonian, Hungary) were analysed to investigate their dietary ecology, using several complementary methods ...

Enamel Prism Angle Variation and Hard-Object Feeding in Cercopithecoids With Known Diets. [PDF]

Am J Biol Anthropol
Left: Cercocebus atys specimen 16–9 third molar showing Phase II enamel prism angle (angle between prism path and wear facet) and wear angle (angle between wear facet and enamel dentin junction (EDJ)). Scatterplot of prism vs. wear angles for the Phase II wear facet. Note the higher angles for Cercocebus.

The Meaning of Mangabey Molars (And Premolars). [PDF]

Evol Anthropol
ABSTRACT The postcanine teeth of mangabeys (members of Cercocebus and Lophocebus) have figured prominently in discussions about the relationship between hard‐object feeding and dental form. Grey‐cheeked mangabeys (Lophocebus albigena) and sooty mangabeys (Cercocebus atys) both have thickly enameled posterior teeth.
