Mechanical Force Promotes Mitochondrial Transfer From Macrophages to BMSCs to Enhance Bone Formation

Cell Proliferation, EarlyView.
Mechanical tension activates Drp1‐mediated mitochondrial fission in macrophages, facilitating the release of Mito‐EVs that are subsequently transferred to BMSCs. Additionally, the CD200R‐CD200 interaction enhances the uptake of these mechanically stimulated macrophage‐derived Mito‐EVs by BMSCs, ultimately promoting osteogenic differentiation.

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

Dental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...

Noise Exposure in a Dental Teaching Hospital: Investigations and Recommendations for Dental Personnel

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Exposure to excessive noise is a highly preventable occupational risk, with irreversible side effects that may negatively impact an individual's quality of life, such as noise‐induced hearing loss and tinnitus. Dental personnel may be at particular risk due to their exposure to high levels of noise from dental equipment.
