Dentinogenesis imperfecta type II dentin: nanostructural mechanics analysis.

Objectives: This study investigated the nanomechanical properties, microstructure, and composition of dentinogenesis imperfecta type II (DGI-II) peritubular dentin (PTD) and intertubular dentin (ITD) and examined the correlations between them.

Materials And Methods: Six samples from each of the normal and DGI-II groups were prepared by cutting the midcoronal dentin perpendicular to the dentin tubules. The number and morphology of the dentin tubules were then observed by scanning electron microscopy (SEM).

Dimethyl fumarate modulates M1/M2 macrophage polarization to ameliorate periodontal destruction by increasing TUFM-mediated mitophagy.

Periodontitis is a common oral disease characterized by progressive alveolar bone resorption and inflammation of the periodontal tissues. Dimethyl fumarate (DMF) has been used in the treatment of various immune-inflammatory diseases due to its excellent anti-inflammatory and antioxidant functions. Here, we investigated for the first time the therapeutic effect of DMF on periodontitis.

Integrated analysis of transcriptome and proteome reveals a core set of genes involved in osteoblast under oxidative stress.

Osteoblasts dysfunction, induced by oxidative stress (OS), is a significant contributor to the pathogenesis of osteoporosis. However, the genes implicated in regulating osteoblast dysfunction remain unclear. Here, we employed the hydrogen peroxide (HO)-induced osteoblast dysfunction model to assess its impact on osteoblast phenotype and to conduct transcriptome and proteome analyses in osteoblasts under OS.

Synthesis and Antiosteoporotic Characterization of Diselenyl Maleimides: Discovery of a Potent Agent for the Treatment of Osteoporosis by Targeting RANKL.

To discover new osteoclast-targeting antiosteoporosis agents, we identified forty-six diselenyl maleimides, which were efficiently prepared using a novel, simple, and metal-free method at room temperature in a short reaction time. Among them, showed the most marked inhibition of osteoclast differentiation with an value of 0.36 ± 0.
