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: The study evaluated the effects of using iloprost, MTA, and MTA-iloprost as pulp capping materials on pulpal inflammation and tertiary dentin formation in rat molars. Results showed similar pulpal responses in all groups, suggesting that mixing MTA with iloprost might not have significant clinical benefits.

Summary: The aim of direct pulp capping (DPC) is to promote pulp healing and mineralized tissue barrier formation by placing a dental biomaterial directly over the exposed pulp. Successful application of this approach avoids the need for further and more extensive treatment. This review focuses on the DPC procedure, the materials used, and their mechanisms of action to promote pulpal healing.

Summary: MTA can promote early differentiation of IPMSCs into odontoblasts, while MTA combined with PRP can stimulate calcified granule and dentin bridge formation through calcium mineral deposition. This combination is an effective method for activating endogenous dental pulp stem cells into odontoblasts in the early stages of pulp regeneration.

Summary: This study developed potential dental pulp capping material by coating mineral trioxide aggregate/hydroxyapatite (MTA/HA) on polycaprolactone (PCL) electrospun membranes. The fabricated membranes were characterized and tested for biocompatibility and cell adhesion, spreading, and migration. The results showed that the PCLMTA membrane exhibited better cell adhesion, spreading, and migration.

Summary: Results of the study showed a significant difference in hard tissue bridge formation with ProRoot MTA, while RetroMTA performed better in terms of continuity, morphology, and inflammatory reaction. Although RetroMTA healed pulpal tissue faster, it seemed to be more of a reparative process compared to ProRoot MTA.

Summary: This study aimed to compare the histopathological response of dental pulp after direct pulp capping using two different materials, exogenous nitric oxide (NOC-18) and Mineral Trioxide Aggregate (MTA), in dogs' teeth. The results showed that the active status of the odontoblasts layer was significantly higher in the NOC-18 group compared to the MTA group after one month. However, there was no significant difference between the two groups in terms of dentine bridge formation after three months.

Summary: This study aimed to investigate fracture initiation criteria of resin composites (RCs) at the micro-scale and evaluate the impact of filler shapes on RCs' flexural properties. Experimental RCs with irregular-shaped silica fillers were compared to models with sphere-shaped fillers, showing that irregular-shaped fillers led to significantly greater elastic modulus values and flexural strength. Ultimately, optimizing filler shapes can improve the mechanical strength of RCs.

Summary: The study evaluated the optical properties of supra-nano spherical fillers with different diameters and the color matching ability of resin composites. Results showed that both 150-nm and 260-nm nano fillers had uniform spherical shape and produced structural colors close to blue and yellow. The experimental RC could reflect base RC colors via the matrix resin, suggesting its ability to enhance color matching effects.

Summary: The study demonstrates that glycated collagen containing AGEs enhances calcification of RDPCs without affecting cell proliferation or differentiation. This form of calcification may lead to cytotoxicity, with glycated collagen exhibiting negative polarity that facilitates the formation of calcium phosphate crystals.

Summary: SAMP8 mice exhibited reduced development of the disto-lingual cusp in the lower second molar compared to SAMR1 mice. Aged SAMP8 mice also showed severe wear of the entoconid in the lower second molar. These findings suggest that SAMP8 mice may serve as a potential model for studying genetic causes of distal reduction of molar cusp size.

Summary: This study evaluated the biological performance of lithium-modified surface pre-reacted glass fillers (S-PRG/Li-100 mM) compared to mineral trioxide aggregate (MTA) and S-PRG without additives. The results showed that S-PRG/Li-100 mM exhibited similar biocompatibility to MTA and S-PRG, promoted apatite formation, and had better sealing capability and antibacterial activity than MTA.

Summary: This study evaluated the biological effects of different types of root canal sealers on surrounding tissues. The results showed that all sealers were in contact with the surrounding tissue and had unique immune and inflammatory modulatory effects. Calcium and phosphorus accumulation was observed only in the bio-glass-containing sealer. These findings can guide future research and comparisons with new generations of materials.

Summary: In this study, a caries-induced pulpitis model was established to evaluate the inflammatory changes in reversible pulpitis induced by caries infection. It was found that M2 macrophages were predominant in moderate caries-stimulated pulp, while M1 macrophages were predominant in severe caries-stimulated pulp. After pulp capping, M2 macrophages played an important role in the early stages of wound healing in reversible pulpitis.

Summary: In this study, it was found that perfluorooctanoic acid (PFOA) negatively affects tooth enamel development through cell death mechanisms involving necrosis/necroptosis and apoptosis, mediated by the ROS-MAPK/ERK signaling pathway. PFOA also suppressed cell proliferation and viability. This research provides initial evidence that PFOA could potentially contribute to cryptogenic enamel malformation.

Summary: Objective of this study was to compare the effects of using sodium hypochlorite and two different concentrations of ethylenediaminetetraacetic acid (EDTA) solution on removal of the smear layer and decalcification of the root canal dentin in an experimental root canal model and an immersion model. Results showed that the experimental design affected the residual smear layer and decalcification of the root canal dentin. EDTA and NaOCl irrigation did not cause erosion in the root canal dentin in the root canal model.

Summary: The treatment of large external cervical resorption lesions can be difficult and result in non-restorable teeth. Intentional replantation is a potential option depending on the location and extent of the resorption. This case report presents a successful management of a large resorption lesion with intentional replantation and tooth rotation. The patient, a female, had an extensive palatal resorption on the maxillary lateral incisor that was not amenable to nonsurgical treatment, and a deliberate replantation with rotation was planned and performed.

Summary: Autologous tooth transplantation is an effective method for replacing missing teeth, especially when there is a suitable donor tooth. It can be performed immediately after extraction or delayed when the recipient site has a large bone defect. This case report illustrates the success of delayed tooth transplantation by monitoring bone formation at the recipient site using CT images.
