Wearing down the constraints of low magnification tooth microwear analysis: reproducibility and variability of results based on extant ungulates [PDF]

PalZ, 2021
Low magnification dental microwear analysis is a widespread dietary proxy for palaeoenvironmental analyses. The limitations of the method, such as observer bias or variation of microwear scars between different tooth positions, are still not quite ...

Trophic evolution in ornithopod dinosaurs revealed by dental wear [PDF]

Nature Communications
Ornithopod dinosaurs evolved numerous craniodental innovations related to herbivory. Nonetheless, the relationship between occlusion, tooth wear rate, and tooth replacement rate has been neglected. Here, we reconstruct tooth wear rates by measuring tooth

On the use of dental microwear texture analysis to determine aetiology and assess wear of dental tissues for clinical evaluation [PDF]

Biosurface and Biotribology
Here, we present and synthesise some recent collaborative efforts in our laboratories to establish protocols for using dental microwear texture analysis, originally developed to reconstruct diets of fossil mammals and to aid in the clinical assessment of

Exploratory Analysis of Objective Outcome Measures for the Clinical Assessment of Erosive Tooth Wear [PDF]

Diagnostics, 2023
This study proposed using enamel surface texture and thickness for the objective detection and monitoring of erosive tooth wear (ETW), comparing them to the standard subjective Basic Erosive Wear Evaluation (BEWE).

Neandertal predation agenda reveals seasonal strategies during MIS 5–4 transition in Axlor, northatlantic Iberia [PDF]

Scientific Reports
As hunter-gatherers, neandertal groups were mobile, moving within their territory based on the availability of targeted resources. Their mobility was an integral part of their subsistence strategies.

Inter-microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument-specific correction equations for meta-analyses using published data.

The Anatomical Record, EarlyView.
Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three-dimensional topographic data from microscopic regions of tooth surfaces have been collected, and ...

3D tooth microwear texture analysis in fishes as a test of dietary hypotheses of durophagy [PDF]

Surface Topography: Metrology and Properties, 2015
An understanding of how extinct animals functioned underpins our understanding of past evolutionary events, including adaptive radiations, and the role of functional innovation and adaptation as drivers of both micro- and macroevolution.

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.

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.

Assessing tooth wear progression in non-human primates: a longitudinal study using intraoral scanning technology [PDF]

PeerJ
Intraoral scanners are widely used in a clinical setting for orthodontic treatments and tooth restorations, and are also useful for assessing dental wear and pathology progression.
