Summary: The use of stem cells for tissue regeneration is a prominent trend in regenerative medicine and tissue engineering. Dental pulp stem cells (DPSCs) have attracted attention due to their ability to differentiate into osteoblasts and odontoblasts. This study explored the biological responses of human DPSCs to a purified 3D chitin scaffold derived from the marine demosponge Aplysina fistularis. Results showed that the chitin scaffold, especially with hydroxyapatite (HAp) modification, supported cell adhesion, proliferation, and differentiation.

Summary: The study aimed to investigate the role of VEGFR-2 in odontoblast differentiation of dental pulp stem cells (DPSCs) by knocking down the expression of VEGFR-2. The results showed that VEGFR-2 is crucial for odontoblast differentiation in DPSCs, and deficiency of VEGFR-2 may impair the differentiation of odontoblast cells.

Summary: The study examined the effects of different pulp capping agents on human dental pulp stem cells. The results showed that platelet-rich fibrin (PRF) had the highest cell viability and the greatest potential to enhance cell proliferation and differentiation. On the other hand, Tetric N-Bond was found to be ineffective as a pulp capping agent. Overall, PRF was the most effective in maintaining the viability of human dental pulp stem cells compared to the other tested materials.

Summary: SFRP1 plays a crucial role in dentinogenesis and promoting reparative dentin formation, as demonstrated by its effects on odontoblastic differentiation and mineralized nodule formation. The strong expression of SFRP1 in mature odontoblasts indicates its importance in dental pulp preservation and response to injury. Additionally, SFRP1 regulates odontoblast-related gene expression, particularly BMP-2, affecting the formation and structure of reparative dentin.

Summary: This study investigated the morphology, chemistry, thermal characteristics, cytocompatibility, and osteogenic potential of solid and porous phosphate-based glass microspheres for potential use as pulp-capping materials. Through various tests, it was found that both solid and porous GMs showed good compatibility with dental pulp stem cells and could support cell attachment, spreading, and viability. However, cells grown in GMs' extracts showed higher viability but less mineralization compared to direct contact with GMs. Therefore, both types of GMs have potential applicability as pulp-capping materials.

Summary: The study aimed to evaluate the dental pulp responses to rhEPO and/or MTA in pulp capping of inflamed dental pulp in vivo. Pulp capping with rhEPO or MTA + rhEPO resulted in lower inflammation and higher mineralization scores compared to untreated control. Capping with rhEPO or MTA + rhEPO resulted in a favorable effect that was similar or even superior to that of MTA.

Summary: Dental pulp plays a crucial role in maintaining tooth function and pulp-regeneration therapy shows promise in clinical practice. However, the mechanisms of pulp regeneration and the role of dental stem cells are not fully understood. This study used single-cell RNA sequencing analysis to explore the development of dental pulp and stem cells at different stages. The results revealed temporal changes in the composition of pulp cells and identified subpopulations of odontoblasts and mesenchymal stem cells. These findings may provide insights into tooth development and improve the success of dental pulp regeneration.

Summary: This study investigated the role of sortilin 1 (SORT1) in the odontoblastic differentiation of human dental pulp-derived stem cells (hDPSCs). SORT1 expression was found in hDPSCs expressing the mesenchymal stem cell markers CD44 and CD90. SORT1-positive hDPSCs showed higher alkaline phosphatase (ALP) staining, indicating enhanced odontoblastic differentiation. The interactions between SORT1 and p75NTR, as well as the involvement of the JUN N-terminal kinases (JNK)/JUN signaling pathway, were also demonstrated.

Summary: The microbial profile, and levels of endotoxin (LPS) and lipoteichoic acid (LTA), in infected dentine and root canals of teeth with irreversible pulpitis were investigated. Root canal preparation effectively reduced the levels of bacteria, LPS and LTA, while intracanal medication did not significantly reduce bacterial levels but led to a significant decrease in LTA levels.

Summary: This study aimed to investigate the potential regulatory pathways of IL-1 beta production by monitoring the effects of periodontal pathogens Fn and Pg on inflammasomes and their regulators in HGFs. The results showed that Fn and Pg, especially when combined with ATP exposure, could dysregulate NLRP3, AIM2, IL-1 beta, ASC, and other inflammasome components and regulators, ultimately affecting the production of IL-1 beta.

Summary: The aim of this study was to develop an endodontic cement using bovine bone-derived hydroxyapatite (BHA), Portland cement (PC), and a radiopacifier. The results showed that the addition of 10% and 20% BHA improved the mechanical strength of the cement while maintaining similar radiopacity and biocompatibility to ProRoot MTA. This study is important for enhancing the properties of endodontic cements.

Summary: Enamel renal syndrome (ERS) is a rare disorder caused by mutations in FAM20A, which may lead to gingival fibromatosis. Proteomic analysis revealed dysregulation of proteins related to extracellular matrix organization and mineralization in ERS patients, suggesting that TGF beta pathway could play a central role in the pathogenesis.

Summary: This study successfully isolated and cultured cHDPCs and ncHDPCs from healthy and inflamed dental pulp tissue respectively. The growth characteristics and differentiation abilities were not significantly different between the two types of HDPCs. However, the expression of certain genes such as TLR-2 and IL-6 was significantly higher in cHDPCs, indicating an inflammatory phenotype in the inflamed dental pulp.

Summary: Exciting opportunities exist within regenerative endodontics for the development of targeted biomaterials that harness epigenetic machinery to control pulpitis and stimulate repair. In this study, small RNA sequencing and bioinformatic analysis were used to establish a miRNA expression profile for mineralising dental pulp cells (DPCs) and examine their interaction with histone deacetylase inhibitors and DNA methyltransferase inhibitors. The results showed that these inhibitors induced mineralisation but reduced cell growth, suggesting an increased and dynamic interaction between miRNA and epigenetic modifiers during DPC reparative processes.

Summary: This systematic review examined the effects of nano-sized cement particles on the properties of calcium silicate-based cements. A literature search was conducted and 17 eligible studies were included. The results showed that nano-calcium silicate-based cements have better physical, mechanical, and biological properties compared to commonly used cements. However, there were deficiencies in characterizing and verifying the nano-particle size, and the presence of additives may have influenced the properties.

Summary: This article provides a contemporary review of the potential beneficial effects of nanosized hydroxyapatite (nHAP) on caries lesions demonstrated in in vitro studies. Data showed that nHAP has the potential to promote mineralization in initial caries and has antimicrobial effects through metal substitution. Metal-substituted fluorhydroxyapatite nanoparticles can potentially possess dual action property and enhanced chemical stability and bioactivity, providing a promising synergistic strategy for the development of dental therapeutics.

Summary: This study identified optimized parameters for periapical tissue fluid (PTF) paper point sampling and compared the proteomes of PTF from teeth with normal apical tissues (NAT) and asymptomatic apical periodontitis (AAP) using high-throughput proteomic analysis. The results showed that some proteins were closely associated with AAP and had good diagnostic performance. The findings provide a potential biomarker network for clinical applications and further validation is needed.
