Wnt-directed CXCL12-expressing apical papilla progenitor cells drive tooth root formation [PDF]
Nature CommunicationsThe tooth root is a critical component of the tooth anchored to surrounding alveolar bones. Tooth root formation is driven by cells in the apical papilla (AP) that generate new dentin-forming odontoblasts at the root-forming front. Mesenchymal stem cells

Bmp9 modulates cell proliferation and intercellular junctions in HERS during tooth root development [PDF]
Genes and DiseasesTooth formation is a highly orchestrated process that precisely regulates the size and shape of the tooth. During typical tooth development, Hertwig's epithelial root sheath (HERS) interacts with mesenchymal cells to direct the elongation of the tooth ...

Transparent dentin region in the tooth root. [PDF]
Clin Case Rep, 2020 AbstractTransparent dentin in the tooth root forms during the aging process. The transparent dentin is weaker than normal opaque dentin, which may explain the occurrence of root dentin fractures in aged individuals. Tooth fractures are caused by the brittleness of the transparent dentin.

Parathyroid hormone receptor signalling in osterix-expressing mesenchymal progenitors is essential for tooth root formation [PDF]
Nature Communications, 2016 Dental root formation is a dynamic process in which mesenchymal cells migrate toward the site of the future root, differentiate and secrete dentin and cementum. However, the identities of dental mesenchymal progenitors are largely unknown.

Dynamic Simulation of Cracked Spiral Bevel Gear Pair Considering Assembly Errors
Machines, 2022 The tooth root crack fault is a common fault type of the spiral bevel gear pair (SBGP). Affected by the strong bearing capacity, the early crack fault of the SBGP cannot be found in time.

Tooth Root Bending Fatigue Performance of Shot Peening TM210A Steel Spur Gear
Advances in Materials Science and Engineering, 2022 Tooth root bending fatigue performance is the primary consideration in gear design. To investigate the difference between the tooth root fatigue performances of shot peened and base material, TM210A steel gears and double-tooth pulsating bending fatigue ...
