Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

VIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

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

Australian 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 ...

Interpretation of the concepts of dentinal tubule and dentinal canaliculus

Regulatory Mechanisms in Biosystems
The biology of dentin occupies a central place in the theory of tooth integrity as an organ, and knowledge about the microstructure of dentin changes with the development of new research methods, such as scanning electron microscopy.

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

Cell 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.

HDAC inhibitor LMK-235 promotes the odontoblast differentiation of dental pulp cells

Molecular Medicine Reports, 2017
The role of dental pulp cells (DPCs) in hard dental tissue regeneration had received increasing attention because DPCs can differentiate into odontoblasts and other tissue-specific cells.

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

Cell 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.

Expression of nerve growth factor (NGF), TrkA and p75NTR in developing human foetal teeth

Frontiers in Physiology, 2016
Nerve growth factor (NGF) is important for the development and the differentiation of neuronal and non-neuronal cells. NGF binds to specific low- and high-affinity cell surface receptors, respectively p75NTR and TrkA. In the present study, we examined by

Three‐Year Clinical and Economic Evaluation of Selective Caries Removal and Full Pulpotomy for Extensive Caries: An Exploratory Randomised Controlled Trial

International Endodontic Journal, EarlyView.
ABSTRACT Aim The aim of this study was to compare pulp survival following selective caries removal (SCR) and full pulpotomy treatment in teeth with extensive caries over 3 years. Methodology This two‐arm, exploratory randomised controlled trial included vital mature permanent teeth with extensive primary or secondary caries diagnosed radiographically ...
