Mechanical Changes in Human Dental Pulp Stem Cells during Early Odontogenic Differentiation
Cell adhesion and migration in bioactive scaffolds require actin cytoskeleton remodeling and focal adhesion formation. Additionally, human dental pulp stem cells (hDPSCs) undergo several changes in their mechanical properties during odontogenic differentiation. The effect of factors essential for odontogenesis on actin stress fiber elasticity and focal adhesion formation is not known. (Source: Journal of Endodontics)

The Role of Integrin αv in Proliferation and Differentiation of Human Dental Pulp Cell Response to Calcium Silicate Cement
It has been proved that integrin αv activity is related to cell proliferation, differentiation, migration, and organ development. However, the biological functions of integrin αv in human dental pulp cells (hDPCs) cultured on silicate-based materials have not been explored. The aim of this study was to investigate the role of integrin αv in the proliferation and odontogenic differentiation of hDPCs cultured with the effect of calcium silicate (CS) cement and β-tricalcium phosphate (TCP) cement.

Direct Pulp Capping after a Carious Exposure Versus Root Canal Treatment: A Cost-effectiveness Analysis
Excavation of deep caries often leads to pulpal exposure even in teeth with sensible, nonsymptomatic pulps. Although direct pulp capping (DPC) aims to maintain pulpal health, it frequently requires follow-up treatments like root canal treatment (RCT), which could have been performed immediately after the exposure, with possibly improved outcomes. We quantified and compared the long-term cost-effectiveness of both strategies. (Source: Journal of Endodontics)

Anesthetic Comparisons of 4% Concentrations of Articaine, Lidocaine, and Prilocaine as Primary Buccal Infiltrations of the Mandibular First Molar: A Prospective Randomized, Double-blind Study
Studies have shown the superiority of 4% articaine with 1:100,000 epinephrine over 2% lidocaine with 1:100,000 epinephrine when used as a primary buccal infiltration of the mandibular first molar. A study using other 4% anesthetic formulations may help determine the role of concentration in the increased efficacy of 4% articaine. The authors conducted a prospective randomized, double-blind, crossover study comparing the pulpal anesthesia obtained with 4% concentrations of articaine, lidocaine, and prilocaine formulations as primary buccal infiltrations of the mandibular first molar.

Osteo-/Odontogenic Differentiation of Induced Mesenchymal Stem Cells Generated through Epithelial–Mesenchyme Transition of Cultured Human Keratinocytes
Revascularization of necrotic pulp has been successful in the resolution of periradicular inflammation; yet, several case studies suggest the need for cell-based therapies using mesenchymal stem cells (MSCs) as an alternative for de novo pulp regeneration. Because the availability of MSCs may be limited, especially in an aged population, the current study reports an alternative approach in generating MSCs from epidermal keratinocytes through a process called epithelial-mesenchymal transition (EMT).

Root Canal Therapy Reduces Multiple Dimensions of Pain: A National Dental Practice-based Research Network Study
Initial orthograde root canal therapy (RCT) is used to treat dentoalveolar pathosis. The effect RCT has on pain intensity has been frequently reported, but the effect on other dimensions of pain has not. Also, the lack of large prospective studies involving diverse groups of patients and practitioners who are not involved in data collection suggest that there are multiple opportunities for bias to be introduced when these data are systematically aggregated.

Expression Features of DNA Methylcytosine Dioxygenase Ten-eleven Translocation 1 in Human Dental Pulp Cells
Human dental pulp cells (hDPCs) can specifically generate reparative dentin under external stimuli, and numerous mechanisms are involved in their odontogenic differentiation process. Ten-eleven translocation 1 (TET1) is a recently discovered DNA dioxygenase that plays important roles in promoting DNA demethylation and transcriptional regulation. Although several studies regarding its effect on cell differentiation and proliferation have been conducted, the expression and function of TET1 have not yet been characterized in hDPCs.

Hydration of Biodentine, Theracal LC, and a Prototype Tricalcium Silicate–based Dentin Replacement Material after Pulp Capping in Entire Tooth Cultures
The calcium-releasing ability of pulp-capping materials induces pulp tissue regeneration. Tricalcium silicate–based materials produce calcium hydroxide as a by-product of hydration. Assessment of hydration and calcium ion leaching is usually performed on samples that have been aged in physiological solution for a predetermined period of time. The hydration and activity of the materials in vivo may not be similar to those displayed in vitro because of insufficient fluid available in contact with dentin. (Source: Journal of Endodontics)

Micromorphology of the Dental Pulp Is Highly Preserved in Cancer Patients Who Underwent Head and Neck Radiotherapy
Teeth are often included in the radiation field during head and neck radiotherapy, and recent clinical evidence suggests that dental pulp is negatively affected by the direct effects of radiation, leading to impaired sensitivity of the dental pulp. Therefore, this study aimed to investigate the direct effects of radiation on the microvasculature, innervation, and extracellular matrix of the dental pulp of patients who have undergone head and neck radiotherapy.

A Novel Treatment for Propagated Crown Fractures
A major complication after endodontic treatment is persistent pain on biting or chewing. Although unsuccessful endodontic treatment can account for such pain, pain to chewing and biting can also be a result of an unsupported or propagated crown fracture. Crown fractures that extend apically result in deterioration of the localized periodontium and ultimate loss of the tooth. To date, no predictable treatment for apically extending crown fractures exists. (Source: Journal of Endodontics)
