Introduction: Peripheral nerve injuries, resulting from trauma or medical interventions, present significant clinical challenges due to their severe physiological and functional impacts. Despite various therapeutic approaches, optimal methods for promoting nerve regeneration remain difficult to obtain. This study is a preliminary step towards the future use of chitosan nerve guide conduits combined with human dental pulp stem cells and their conditioned media to promote nerve regrowth in a rat model with severe sciatic nerve damage.
Methods: Preliminary characterization of conditioned medium from human dental pulp stem cells identified key regenerative biomarkers using a Multiplexing LASER Bead analysis. The human dental pulp stem cells' cytocompatibility with Reaxon® chitosan biomaterial was confirmed through viability and metabolic assays in a PrestoBlue assay, along with scanning electron microscopy and energy-dispersive X-ray spectroscopy analyses.
Results: These assessments validated the therapeutic potential of the combinations for nerve regeneration.
Discussion: Future experiments will involve applying these combinations in a rat model, with functional assessments to evaluate efficacy. This research aims to establish human dental pulp stem cells and nerve guide conduits as viable treatments for peripheral nerve injury, offering promising directions for clinical applications.

Supernumerary tooth-derived pulp stem cells (SNTSCs) hold promise for endodontic regeneration, yet little is known about the similarities and diversities of SNTSCs relative to other dental-derived mesenchymal stem cells. Herein, we compare the biological characteristics of SNTSCs with dental pulp stem cells (DPSCs) and stem cells from human exfoliated deciduous teeth (SHED). Cell proliferation, migration, and odontogenic differentiation potential, as well as viability and aging-related phenotype after long-term storage, were evaluated.

Background: Regeneration dentistry demonstrates significant challenges due to the complexity of different dental structures. This study aimed to investigate osteogenic differentiation of human pulp stem cells (hDPSCs) cultured on a 3D-printed poly lactic acid (PLA) scaffold coated with nano-hydroxyapatite (nHA) and naringin (NAR) as a model for a dental regenerative.
Methods: PLA scaffolds were 3D printed into circular discs (10 × 1 mm) and coated with nHA, NAR, or both.

Asthma, a prevalent allergic disease affecting approximately 300 million individuals globally, remains a significant public health challenge. Mesenchymal stromal cells (MSCs) and hepatocyte growth factor (HGF), both recognized for their immunomodulatory properties, hold therapeutic potential for asthma. However, their precise mechanisms remain underexplored.

Autotransplantation of immature third molars is an effective treatment option, offering high success rates, minimal complications, and notable improvements in occlusal function and dental aesthetics. This study aims to review and evaluate the available evidence specifically on the survival and success rates of immature autotransplanted third molars and to identify prognostic factors that influence these outcomes. A comprehensive search was conducted in the Elsevier Journals (ScienceDirect), MEDLINE (PubMed), and Dentistry & Oral Sciences Source (EBSCOhost) databases up to May 2024.
