The objective of this study was to investigate the odontoblastic differentiation of dental pulp stem cells (DPSC) by biodegradable hydrogels incorporating simvastatin micelles, both in vitro and in vivo. Simvastatin (ST) was incorporated into the micelles of gelatin grafted with L-lactic acid oligomers (LAo) to allow water-solubilization. The simvastatin-LAo-grafted gelatin (LAo-g-gelatin) micelles were mixed with gelatin, followed by chemical crosslinking to form gelatin hydrogels (ST Mi/GH). The ST Mi were released from the gelatin hydrogel granules (GH) through enzymatic degradation. The ST Mi enhanced alkaline phosphatase activity, calcium deposition, and bone morphogenic protein-2 secretion of DPSC. When implanted subcutaneously into mice, the ST Mi/GH treated group exhibited increased dentin sialoprotein and calcium deposition, compared with those treated with GH plus free ST. It is possible to achieve odontoblastic differentiation of DPSC through the controlled release of ST from GH.

Aim: Odontogenesis is a complex and highly regulated biological process that involves a range of molecular mechanisms. Among these, Ki67 and Cyclin D1 are crucial cell cycle regulators that play pivotal roles in controlling cell proliferation during tooth development. This study aims to provide detailed insights into the expression patterns and functional significance of Ki67 and Cyclin D1 in tooth development.

Patients with diabetes mellitus (DM) have an increased risk of tooth decay caused by alterations in their tooth development and their oral environment, as well as a tendency to present with pulp infection due to compromised immune response. The present study analyzed the characteristic alterations in tooth development under DM conditions using incisors from type 2 diabetic mouse model (T2DM mice). In micro-CT analyses, T2DM mice showed delayed dentin and enamel formation.

Introduction: Establishing an optimized regenerative microenvironment for pulp-dentin complex engineering has become increasingly critical. Recently, exosomes have emerged as favorable biomimetic nanotherapeutic tools to simulate the developmental microenvironment and facilitate tissue regeneration.
Objectives: This study aimed to elucidate the multifaceted roles of exosomes from human dental pulp stem cells (DPSCs) that initiated odontogenic differentiation while sustaining mesenchymal stem cell (MSC) characteristics in odontogenesis, angiogenesis, and neurogenesis during pulp-dentin complex regeneration.

Tooth root development is a complex process essential for tooth function, yet the role of root dentin development in tooth morphogenesis is not fully understood. Optineurin (OPTN), linked to bone disorders like Paget's disease of bone (PDB), may affect tooth root development. In this study, we used single-cell sequencing of embryonic day 16.

Background: Regenerative endodontics requires an innovative delivery system to release antibiotics/growth factors in a sequential trend. This study focuses on developing/characterizing a thermoresponsive core-shell hydrogel designed for targeted drug delivery in endodontics.
Methods: The core-shell chitosan-alginate microparticles were prepared by electrospraying to deliver bone morphogenic protein-2 for 14 days and transforming growth factor-beta 1 (TGF-β1) for 7-14 days.
