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.

Buccal dental-microwear and dietary ecology in a free-ranging population of mandrills (Mandrillus sphinx) from southern Gabon. [PDF]

PLoS ONE, 2017
Analyses of dental micro- and macro-wear offer valuable information about dietary adaptations. The buccal surface of the teeth does not undergo attrition, indicating that dental microwear may directly inform about food properties. Only a few studies have,

Dietary behaviour of man-eating lions as revealed by dental microwear textures [PDF]

Scientific Reports, 2017
Lions (Panthera leo) feed on diverse prey species, a range that is broadened by their cooperative hunting. Although humans are not typical prey, habitual man-eating by lions is well documented. Fathoming the motivations of the Tsavo and Mfuwe man-eaters (

Testing Dietary Hypotheses of East African Hominines Using Buccal Dental Microwear Data. [PDF]

PLoS ONE, 2016
There is much debate on the dietary adaptations of the robust hominin lineages during the Pliocene-Pleistocene transition. It has been argued that the shift from C3 to C4 ecosystems in Africa was the main factor responsible for the robust dental and ...

Can dental microwear textures record inter-individual dietary variations? [PDF]

PLoS ONE, 2010
BACKGROUND: Dental microwear analyses are commonly used to deduce the diet of extinct mammals. Conventional methods rely on the user identifying features within a 2D image.

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.

Dental topography and microwear texture in Sapajus apella

Biosurface and Biotribology, 2017
Dental microwear texture pattern has been associated with aspects of diet for a broad range of mammalian taxa. The basic idea is that soft, tough foods are sheared with a steeper angle of approach between opposing occlusal surfaces, whereas hard, brittle

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.

Diet-related buccal dental microwear patterns in Central African Pygmy foragers and Bantu-speaking farmer and pastoralist populations. [PDF]

PLoS ONE, 2013
Pygmy hunter-gatherers from Central Africa have shared a network of socioeconomic interactions with non-Pygmy Bantu speakers since agropastoral lifestyle spread across sub-Saharan Africa.

Surface Replication, Fidelity and Data Loss in Traditional Dental Microwear and Dental Microwear Texture Analysis. [PDF]

Sci Rep, 2019
AbstractDental microwear studies often analyze casts rather than original surfaces, although the information loss associated with reproduction is rarely considered. To investigate the sensitivity of high magnification (150x) microwear analysis to common surface replication materials and methods, we compared areal surface texture parameters (ISO 25178-2)
