Flexural Properties, Wear Resistance, and Microstructural Analysis of Highly Filled Flowable Resin Composites.

Oper Dent

September 2024

*Romain Ceinos, DDS, PhD, faculty of Dental Surgery, Restorative Department, Côte d'Azur University, Nice, France; hospital practitioner, Institute of Bucco-Dental Medicine, Nice University Hospital, Nice, France; Innovative Dental Materials and Interfaces Research Unit (URB2i), Paris-Cité, France.

Objective: This study aimed to evaluate the flexural properties and two-body wear resistance of nine highly filled flowable resin composites relative to those of viscous and conventional low-filled flowable composites. In addition, scanning electron microscopy (SEM) analysis of the microstructures was performed.

Methods And Materials: For each resin composite group (n=12), 12 specimen bars (25 mm × 2 mm × 2 mm) were fabricated using a silicon mold for performing flexural strength (FS), flexural modulus (E), flexural toughness (FT), Weibull modulus (m) tests, and SEM microstructural analysis.

Department of Plastic and Reconstructive Surgery, Institut Universitaire Locomoteur et du Sport, Pasteur 2 Hospital, Côte d'Azur University, Nice, France.

Introduction: Despite the progress in microsurgery in recent decades, neurovascular bundle defects during ring finger injuries still pose challenges for the surgeon. Usually, a reversed venous graft and a non-vascularized nerve graft are utilized to reconstruct this defect. One of the most common challenges encountered when using a venous graft is the caliber mismatch between the graft and the digital arterial ends.

The restoration of endodontically treated teeth (ETT) remains a significant challenge in modern dentistry. These teeth often suffer from substantial structural damage due to both the original pathology and the invasive nature of endodontic procedures. Consequently, ETT are more susceptible to fractures compared to vital teeth, necessitating restorative strategies that can effectively restore both function and aesthetics while minimizing the risk of failure.

Article Synopsis
  • Reactive astrogliosis is a key factor in secondary spinal cord injuries and biomaterials can inhibit astrocyte activation, but the underlying mechanisms are not fully understood.
  • The study identifies the VIM gene as a crucial regulator in reactive astrocytes using whole transcriptome sequencing on a mouse spinal cord injury model, highlighting the role of differentially expressed genes (DEGs) in the extracellular matrix (ECM).
  • The research demonstrates that 3D injectable electrospun fibers effectively reduce reactive astrogliosis by downregulating the VIM gene and disrupting the NF-κB signaling pathway, thus promoting recovery of spinal cord function by preventing further inflammation and neuronal apoptosis.

Background: Novel technologies offer great possibilities for improving patient care, but their adoption varies across different European countries. To successfully integrate these advancements, it is crucial to prioritize patient interests and avoid getting side-tracked by issues that seek to preserve established positions or neglect collaboration. Next-generation sequencing and liquid biopsy in cancer patients hold substantial potential for early diagnosis and reducing suffering, but only if they are effectively implemented into routine health care.

Article Synopsis
  • Planetary defense research is heavily dependent on understanding the mechanical properties of asteroids, which are challenging to assess from Earth.
  • A study of boulders on the asteroid Dimorphos, using data from the DART mission, revealed an estimated internal friction angle of 32.7 ± 2. 5°, indicating they likely formed from impact processing.
  • The similarities between Dimorphos boulders and those on other rubble-pile asteroids (Itokawa, Ryugu, and Bennu) suggest a shared formation process and enhance our understanding of asteroid characteristics and the implications for planetary defense strategies.

The axon initial segment (AIS) is a critical compartment in neurons. It converts postsynaptic input into action potentials that subsequently trigger information transfer to target neurons. This process relies on the presence of several voltage-gated sodium (Na) and potassium (K) channels that accumulate in high densities at the AIS.

Treatment decisions for neovascular age-related macular degeneration (nAMD) in the setting of individualised treatment regimens are adapted to disease activity. The main marker of disease activity and trigger for re-treatment with anti-vascular endothelial growth factor (anti-VEGF) agents is the presence of retinal fluid on optical coherence tomography (OCT). Recently, attention has focused on the impact of residual retinal fluid on nAMD management.

Photoaging, primarily caused by ultraviolet (UV) light, is the major factor in extrinsic skin aging. Existing anti-photoaging strategies mainly focus on early sun protection or repairing damaged skin, lacking a comprehensive treatment strategy. Therefore, this study developed a dressing that actively shields against UV radiation and repairs photoaged skin, offering double protection.

Article Synopsis
  • The study investigates the differences between cerebral amyloid angiopathy-related inflammation (CAA-RI) and biopsy-positive primary angiitis of the CNS (BP-PACNS), focusing on their clinical and radiologic presentations as well as relapse rates.
  • It included 104 patients with CAA-RI and 52 with BP-PACNS, revealing that CAA-RI tends to show more white matter lesions and hemorrhagic features, while BP-PACNS is associated more with headaches and motor deficits.
  • The results indicate significant differences in features between the two conditions, suggesting that they may require different diagnostic approaches and could have varying outcomes in terms of recurrence.

Article Synopsis
  • Strokes are really dangerous, especially for older people, and they can lead to serious problems or even death.
  • Doctors usually use CT and MRI scans to find strokes, but these scans can take a long time and are expensive, making it hard to detect strokes quickly.
  • A new computer program (an AI model) was made to look at 2D pictures of people's faces to find out if they might have had a stroke, helping doctors give faster care before doing more tests.
