Advanced Functional Materials, EarlyView.The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Molecular genetics of tooth development [PDF]
Current Opinion in Genetics & Development, 2009 Organogenesis depends upon a well-ordered series of inductive events involving coordination of molecular pathways that regulate the generation and patterning of specific cell types. Key questions in organogenesis involve the identification of the molecular mechanisms by which proteins interact to organize distinct pattern formation and cell fate ...

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

On a dynamic reaction-diffusion mechanism: The spatial patterning of teeth primordia in the alligator [PDF]
, 1996 It is now well established both theoretically and, more recently, experimentally, that steady-state spatial chemical concentration patterns can be formed by a number of specific reaction–diffusion systems.

Advanced Functional Materials, EarlyView.Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...

Sirt6 loss activates Got1 and facilitates cleft palate through abnormal activating glycolysis
Cell Death and DiseaseCleft palate (CP) is a common congenital craniofacial malformation, which is caused by a combination of genetic and environmental factors. However, its underlying mechanism has not been elucidated.

Reduction of gear pair transmission error with tooth profile modification [PDF]
, 2008 The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Thermally induced mechanical stress in the stator windings of electrical machines [PDF]
, 2018 The lifetime of an electrical machine mainly depends on the thermal overloading. Modern day applications of electrical machines on one hand require compact machines with high power density, while on the other hand force electrical machines to undergo ...

Tooth development - Root development
Swiss dental journal, 2022 Tooth development begins in the human embryo 28 to 40 days after ovulation. Epithelial cells grow into the ectomesenchymal parts of the jaw. An epithelial protrusion develops. Further penetration of the epithelial cells into the ectomesenchyma results in the formation of the dental papilla (Figs. 1, 2 and 3).
