Acid resistance and bond strength of calcium-containing adhesive on ename.
Int Dent J
January 2025
Department of Cariology and Operative Dentistry, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo, Bunkyo-ku, Tokyo, Japan.
Introduction And Aims: Marginal sealing by enamel bonding is important to enhance the durability of the restoration and prevent secondary caries after operative procedure. This study aimed to evaluate the enamel acid resistance and bond strength of an experimental calcium-containing adhesive system.
Methods: All materials were provided by Kuraray Noritake Dental, Inc.

Functional cartilaginous tissues can potentially be engineered by bringing together numerous microtissues (µTs) and allowing them to fuse and re-organize into larger, structurally organized grafts. The maturation level of individual microtissues is known to influence their capacity to fuse, however its impact on the long-term development of the resulting tissue remains unclear. The first objective of this study was to investigate the influence of the maturation state of human bone-marrow mesenchymal stem/stromal cells (hBM-MSCSs) derived microtissues on their fusion capacity and the phenotype of the final engineered tissue.

The differentiation of human induced pluripotent stem cells (hiPSCs) into neural progenitor cells (NPCs) is a promising approach for the treatment of neurodegenerative diseases and regenerative medicine. Dual-SMAD inhibition using small molecules has been identified as a key strategy for directing the differentiation of hiPSCs into NPCs by regulating specific cell signaling pathways. However, conventional culture methods are time-consuming and exhibit low differentiation efficiency in neural differentiation.

Restorative and Aesthetic Dentistry Department, College of Dentistry, University of Baghdad, Baghdad, Iraq.
Aim: 3D-printed scaffolds loaded with healing directed agents could be employed for better treatment outcome in regenerative dentistry. The aim of this study was to fabricate and characterize simple 3D-printed poly lactic acid (PLA) scaffolds coated with nanoHydroxyapatite (nHA), Naringin (NAR), or their combination, and testing their morphological, chemical, mechanical, antibacterial, biocompatible and bioactive properties.
Methodology: Two variants pore sizes, 300 and 700 μm, of 3D-printed PLA disc scaffolds measuring (10 × 1 mm) were fabricated.
FOXG1 promotes osteogenesis of bone marrow-derived mesenchymal stem cells by activating autophagy through regulating USP14.

The osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) is key for bone formation, and its imbalance leads to osteoporosis. Forkhead Box Protein G1 (FOXG1) is associated with osteogenesis, however, the effect of FOXG1 on osteogenesis of BMSCs and ovariectomy (OVX)-induced bone loss is unknown. In our study, FOXG1 expression in BMSCs increases after osteogenic induction.
