VEGFA promotes odonto/osteoblastic differentiation in dental pulp stem cells via ERK/p38 signaling

Journal of Dental Sciences
Background/purpose: Vascular endothelial growth factor A (VEGFA) is a potent angiogenic factor and an essential growth factor for vascular endothelial cells, but its effects on dental pulp stem cells, such as stem cells from human exfoliated deciduous ...

MicroRNA-27a transfected dental pulp stem cells undergo odonto/osteogenic differentiation via targeting DKK3 and SOSTDC1 in Wnt/BMP signaling in vitro and enhance bone formation in vivo

Journal of Translational Medicine
Background MicroRNAs (miRNAs) play a crucial role in cell differentiation through epigenetic regulation of gene expression. In human dental pulp cells, we have identified miRNA-27a being upregulated under inflammatory conditions.

Hematopoietic progenitor cells specifically induce a unique immune response in dental pulp under conditions of systemic inflammation

Heliyon, 2022
Teeth are exposed to various stimuli, including bacterial, thermal, and physical stimuli. Therefore, immune cells present in the normal dental pulp and the immune response to these stimuli have been studied.

Effect of repetitive up-and-down movements on torque/force generation, surface defects and shaping ability of nickel-titanium rotary instruments: an ex vivo study

BMC Oral Health
Background The screw-in effect is a tendency of a nickel-titanium (NiTi) rotary endodontic file to be pulled into the canal, which can result in a sudden increase in stress leading to instrument fracture, and over-instrumentation beyond the apex.
