    Abstract Pediatric endodontics has become popular due to advancements in cleaning, shaping and irrigation systems, resulting in faster and effective removal of infected pulp, saving time, and creating a pathogen-free environment. The patented rotary file system, Kedo-S, designed for primary teeth, introduced a single file generation for efficient pulp therapy. However, there are currently no studies assessing canal preparation in primary mandibular molars using nano-CT (computed Tomography). To evaluate the volumetric changes of two recently introduced pediatric rotary file systems in comparison with conventional hand file systems in primary mandibular molar using an ultra-high resolution nano-CT.

    Abstract Herein, we have used ammonium vanadate (NH₄VO₃) as a redox-additive for the first time to boost the energy density of a flexible supercapacitor. Surprisingly, a significant enhancement in the specific capacitance (Cₛₚ) is attained after the addition of NH₄VO₃ with H₂SO₄ (658 F g–¹) when compared with H₂SO₄ (375 F g–¹). In addition, the energy density conquered with NH₄VO₃/H₂SO₄ (32 Wh kg–¹) is 4.5-fold greater than H₂SO₄ electrolyte at 3 A g–¹ (7 Wh kg–¹). Moreover, the flexible solid-state supercapacitor (FSSC) device with ammonium vanadate/poly(vinyl alcohol)/sulfuric acid (NH₄VO₃/PVA/H₂SO₄) gel electrolyte shows a better electrochemical performance while compared with PVA/H₂SO₄. The electrochemical performance of the working electrode enhanced after the addition of NH₄VO₃ with conventional H₂SO₄ due to the redox reaction between the VO₃– and H⁺ ions.

    Abstract Flexible energy storage devices are the cornerstone to the development of future-generation electronics such as flexible displays on phones, smart bands, laptops, and televisions. The advancement of flexible supercapacitors has turned into an essential task because supercapacitors are designed with the rewards of optimum power and energy density. Owing to the dual function as an electrical double-layer capacitor and a pseudocapacitor, heteroatom-doped graphene is presumed to be a promising electrode material for supercapacitor applications. Herein, we report p-toluenesulfonic acid as the precursor to the formation of sulfur-doped graphene by supercritical fluid-aided processing. Both the existence and nature of S doping in graphene were confirmed with the elemental and X-ray photoelectron spectroscopy techniques. Full cell analysis indicated that the energy density achieved using hydroquinone (HQ) as a redox additive in 1 M H₂SO₄ solution was found to be 27 W h/kg, which is twice that of an aqueous solution of 1 M H₂SO₄ (13 W h/kg). To extend the application of the symmetric cell, a flexible device using polyvinyl alcohol (PVA)/HQ/H₂SO₄ is fabricated. A 3-fold increase in energy density is observed for the flexible solid-state single device using PVA/HQ/H₂SO₄ (E = 21.3 W h/kg) when compared with PVA/H₂SO₄ as an electrolyte (E = 7.7 W h/kg).

    Abstract Successful outcome of pulp therapy depends on good chemomechanical preparation of the canals. This is completed with the help of various upcoming rotary and hand files. However, during this preparation, there might be an apical extrusion of the debris which may result in postoperative complications. The aim of this study was to evaluate and compare the number of debris apically extruded during canal preparation using two different pediatric rotary file systems and conventional hand file systems in primary teeth. 60 primary maxillary central incisors that were extracted due to trauma or untreated dental caries with no signs of resorption were taken. Canal preparation was executed using three different file systems: Group A: Group A hand K file system, Group B Kedo S Plus, Group C Kedo SG Blue. For each of these files using the Myers and Montgomery model, the pre- and post-weight of the eppendorf tube was assessed to quantify the number of apical debris. The maximum extrusion of apical debris was noticed with the Hand K-file system. The least debris was noticed in the Kedo S Plus file system. Statistical analysis revealed that there were highly significant differences in apical extrusion and debris when comparing hand files and rotary files and also between the two rotary files used. Apical debris collection is an unavoidable outcome of canal instrumentation. Among the file systems compared, rotary files had lesser extrusion when compared to hand files. Among the rotary files, Kedo S plus showed normal extrusion compared to SG Blue.
