Tooth vitality and periapical healing: is Biodentine at par with MTA in regenerative endodontics?
Evid Based Dent
January 2025
All India Institute of Medical Sciences, Bathinda, Punjab, India.
Design: The study is a prospective, double-blinded randomised control trial that compares the mineral trioxide aggregate (MTA) and Biodentine as the pulp space barrier material after induction of a periapical blood clot by over-instrumentation for endodontic regeneration in single-rooted mature permanent anterior tooth (closed apex) with apical periodontitis (periapical pathology of more than 3 mm) and having necrosed pulp. A total of 36 patients were included in the study and after randomisation were allocated equally to both the groups out of which 31 patients returned for follow-up over an 18-month period. The treatment protocol consisted of two separate appointments.

We propose a network architecture for electronic skin with an extensive sensor array-crucial for enabling robots to perceive their environment and interact effectively with humans. Fault tolerance is essential for electronic skins on robot exteriors. Although self-healing electronic skins targeting minor damages are studied using material-based approaches, substantial damages such as severe cuts necessitate re-establishing communication pathways, traditionally performed with high-functionality microprocessor sensor nodes.

Dielectric polymer capacitors suffer from low discharged energy density and efficiency due to their low breakdown strength, small dielectric constant and large electric hysteresis. Herein, a synergistic enhancement strategy is proposed to significantly increase both breakdown strength and dielectric constant while suppressing hysteresis, through introducing 2-dimensional bismuth layer-structured NaBiTiO micro-sheets and designing a unique bilayer structure. Excitingly, an ultra-high discharged energy density of 25.

Eur Radiol Exp
January 2025
Department of Diagnostic and Interventional Radiology, Hannover Medical School, Hannover, Germany.
Background: Metasurface coils (MCs) are a promising magnetic resonance imaging (MRI) technology. Aiming to evaluate the image quality of MCs for knee and elbow imaging, we compared signal-to-noise ratio (SNRs) obtained in standard clinical setups.
Methods: Knee and elbow MRI routine sequences were applied at 1.
Validation of an online imitation-inhibition task.
Behav Res Methods
January 2025
Leuphana University Lueneburg, Lueneburg, Germany.
People automatically imitate a wide range of different behaviors. One of the most commonly used measurement methods to assess imitative behavior is the imitation-inhibition task (Brass et al., 2000).
