The Anatomical Record, EarlyView.Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Tooth fracture frequency in gray wolves reflects prey availability
eLife, 2019 Exceptionally high rates of tooth fracture in large Pleistocene carnivorans imply intensified interspecific competition, given that tooth fracture rises with increased bone consumption, a behavior that likely occurs when prey are difficult to acquire. To

In vitro attrition wear resistance of four types of paste-like bulk-fill composite resins
BMC Oral Health, 2022 Background Recently, the application of bulk-fill composite resins has increased significantly. Attrition wear and the consequently increased surface roughness of composite resins are among the causes of restoration failure in the posterior teeth.

The prevalence of impacted permanent maxillary canines in Maltese school children : a pilot study [PDF]
, 1995 The aetiology of ectopic canines is not clear. A number of causes have been put forward such as the long path of eruption of the maxillary canine, lack of guidance by the lateral incisor root, narrow arches, cystic enlargement of the dental follicle ...

Brief Communication: Intertooth and Intrafacet Dental Microwear Variation in an Archaeological Sample of Modern Humans From the Jordan Valley [PDF]
, 2006 Dental microwear was recorded in a Bronze-Iron Age (3570–3000 BP) sample of modern humans recovered from Tell es-Sa'idiyeh in the Jordan Valley. Microwear patterns were compared between mandibular molars, and between the upper and lower part of facet 9 ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Primate dental function and evolution: longitudinal 3D tooth wear in wild baboons
Evolutionary Human SciencesTooth wear constrains feeding efficiency, life history, and survival in mammals, yet its progression in wild populations remains poorly understood. We use high-resolution 3D analysis to quantify occlusal tissue loss over a 3-year period in the upper ...

Copper deficit as a potential pathogenic factor of reduced bone mineral density and severe tooth wear [PDF]
, 2013 SUMMARY: The study evaluated if men and women with severe tooth wear were at increased risk of general bone loss. Enamel biopsies obtained from 50 subjects aged 47.5 ± 5 years showed decreased copper content, which was associated with reduced spine bone ...

Root coverage using a microsurfaced acellular dermal matrix: A retrospective case series
Clinical Advances in Periodontics, EarlyView.Abstract Background Acellular dermal matrices (ADMs) have been used for root coverage for over 25 years, yet few advancements have improved clinical outcomes or reduced complications. This case series evaluated the use of a novel microsurfaced ADM (mADM), which features a microtextured surface designed intended to promote healing and improve graft ...
