Dose‐Dependent Effects of Simulated Clinical Radiotherapy on the Structure and Properties of Root Dentine

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT Head and neck radiotherapy (HNRT) can expose teeth to moderate radiation doses, yet the effects on root dentine under clinically relevant conditions remain unclear. This in vitro study compared dentine subjected to 0, 30, or 50 Gy IMRT. Palatal roots from 35 maxillary molars were allocated to non‐irradiated, 30 Gy (oropharyngeal simulation ...

Crosstalk between nuclear factor I-C and transforming growth factor-β1 signaling regulates odontoblast differentiation and homeostasis. [PDF]

open access: yesPLoS ONE, 2011
Transforming growth factor-β1 (TGF-β1) signaling plays a key role in vertebrate development, homeostasis, and disease. Nuclear factor I-C (NFI-C) has been implicated in TGF-β1 signaling, extracellular matrix gene transcription, and tooth root development.

Kdf1 Regulates Molar Cusp Morphogenesis via the PI3K/AKT/mTOR Signalling Axis

open access: yesCell Proliferation, EarlyView.
Epithelial Kdf1 knockout disrupts molar cusp morphogenesis by promoting inner enamel epithelium proliferation and invagination via PI3K/AKT/mTOR signalling. ABSTRACT Keratinocyte differentiation factor 1 (Kdf1) reportedly plays a significant role in enamel formation.

Intra-pulp temperature increase of equine cheek teeth during treatment with motorized grinding systems : influence of grinding head position and rotational speed [PDF]

open access: yes, 2014
BACKGROUND: In equine practice, teeth corrections by means of motorized grinding systems are standard procedure. The heat resulting from that treatment may cause irreparable damage to the dental pulp. It has been shown that a 5.5degreesC temperature rise

p75NTR Promotes Circadian‐Driven Mineralization During Tooth Development via CK2/PER2 Pathway

open access: yesCell Proliferation, EarlyView.
The diagram illustrates how the circadian rhythm regulates the p75NTR‐CK2‐PER2 axis, driving rhythmic biomineralisation during tooth development. ABSTRACT Circadian rhythm is an essential biological process that synchronises physiological activities with environmental light/dark cycles.

Effects of Synthetic Toll-Like Receptor 9 Ligand Molecules on Pulpal Immunomodulatory Response and Repair after Injuries

open access: yesBiomolecules
Synthetic oligodeoxynucleotides (ODNs) containing unmethylated cytosine–phosphate–guanine (CpG) motifs (CpG-ODNs) are ligand molecules for Toll-like receptor 9 (TLR9), which is expressed by odontoblasts in vitro and dental pulp cells.
