Self-multilayered cell sheet generated by dental pulp stem cells provides a mechanically quantifiable regenerative graft for bone tissue engineering

Abstract Background Mesenchymal stromal cell (MSC) sheets are promising regenerative grafts, but fragile scaffold-free sheets remain difficult to harvest, manipulate, and prepare as mechanically reliable grafts for transplantation. We found that human dental pulp stem cells (DPSC...

Influence of axial motion amplitude on stress generation, canal-centering ability, and motor-recorded torque during XP-endo Shaper instrumentation: an in vitro study

The optimal axial motion amplitude during nickel-titanium rotary canal instrumentation has not yet been fully clarified. To evaluate the effects of axial motion amplitude on shaping behavior and motor-recorded torque during root canal instrumentation using the XP-endo Shaper (XPS...

Association Between Subjective Symptoms, Psychological Stress and Quality of Life Among Older Japanese Adults

Background/Objectives: A crucial issue in Japan, as a rapidly aging society, is supporting the quality of life (QOL) of older adults to ensure they do not require long-term care. This study aims to examine the association between subjective symptoms and psychological stress and Q...
