Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Survival Rates of Amalgam and Composite Resin Restorations from Big Data Real-Life Databases in the Era of Restricted Dental Mercury Use

Bioengineering
Tooth decay, also known as caries, is a significant medical problem that harms teeth. Treatment is based on the removal of the carious material and then filling the cavity left in the tooth, most commonly with amalgam or composite resin. The consequences

Evaluation of resin composites for dental restorations

Procedia Manufacturing, 2019
Abstract In the production of dental restorations, there are, currently, two main types of materials: ceramics and resin composites. These latter kinds are typically suggested because of their quick fabrication, easy reparation and increased crossed link density compared with conventional light-cured materials.

A biomechanical optimized Zr58Cu25Al14Nb3 bulk metallic glass dental implant improves peri‐implant stress distribution and bone quality under physiological loading

BMEMat, EarlyView.
This study reports a novel Zr58Cu25Al14Nb3 bulk metallic glass that possesses high mechanical strength and low elastic modulus, which further promotes efficient mechanotransduction and significantly improves peri‐implant bone quality upon cyclic occlusal loading.
