A Systematic Review of the Comparative Efficacy of Lactobacillus Probiotics and Sodium Hypochlorite as Intracanal Irrigants Against Enterococcus faecalis.

Irrigation plays a pivotal role in the success of root canal treatments. The development of innovative, less hazardous irrigating solutions is necessary because of the inherent limitations of the gold standard, sodium hypochlorite. Since probiotics have proven to be effective in treating common oral diseases such as periodontitis and dental caries, they have gained attention in the field of endodontics as well.

Endodontic Access Cavity Design and Fracture Resistance: A Systematic Review and Meta-Analysis of Conventional vs. Newer Access Cavity.

The era of minimally invasive dentistry has led to the development of new access cavity designs. The impact of various access cavity designs on the fracture resistance of teeth has been extensively studied. The primary aim of this systematic review and meta-analysis is to evaluate and compare the effects of recent modifications in endodontic access cavity design- specifically, conventional, conservative, and truss designs on tooth fracture resistance.

Impact of Cryotreated and Warm Sodium Hypochlorite on Postoperative Pain in Teeth With Symptomatic Irreversible Pulpitis: A Randomized Controlled Trial.

Introduction: The purpose of this study was to evaluate effect of cryotreated and warm sodium hypochlorite (NaOCl) on postoperative pain in patients with symptomatic irreversible pulpitis and symptomatic apical periodontitis.

Methods: Sixty-six individuals with preoperative pain scores of ≥54 mm on the Heft Parker Visual Analogue Pain Scale (HP-VAS) diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis as per the American Association of Endodontists guidelines in mandibular molars were included. The preparation of the access and the root canals was instrumented and irrigated in accordance with a standard protocol.

Effect of Laser Therapy on Postoperative Pain and Endodontic Retreatment: A Systematic Review and Meta-Analysis.

Background: Root canal re-treatment (RCR) cases are considered some of the most challenging cases in the field of endodontics, as they are mostly associated with various iatrogenic errors such as ledge formation, incomplete biomechanical preparation, file separation, and incomplete obturation. These iatrogenic errors lead to defective niches within root canals that may act as reservoirs for various viable microorganisms. Such residual microbial niches may cause postoperative pain even after thorough debridement and reshaping the canals, ultimately leading to a poor prognosis for the tooth.

Efficient Photocatalytic CO Reduction with High Selectivity for Ethanol by Synergistically Coupled MXene-Ceria and the Charge Carrier Dynamics.

The primary factors that govern the selectivity and efficacy of CO photoreduction are the degree of activation of CO on the active surface sites of photocatalysts and charge separation/transfer kinetics. In this context, the rational synthesis of heterostructured MXene-coupled CeO-based photocatalysts with different loading concentrations of TiCMXene via a one-step hydrothermal approach has been undertaken. These photocatalysts exhibit a shift in X-ray diffraction peaks to higher 2θ values and changes in stretching vibrations of 5 wt % TiCMXene/CeO(5-TC/Ce) that indicate interaction between TiCMXene and CeO.

Efficient Photocatalytic Reduction of Hexavalent Chromium by BiVO-Decorated MXene Photocatalysts and Their Charge Carrier Dynamics.

The synergistically co-catalyst-decorated -based heterostructured photocatalysts have been synthesized by a hydrothermal approach with varied loading concentrations of to drive the hexavalent chromium reduction efficiently. The formation of the heterostructured photocatalyst was confirmed by the appearance of X-ray diffraction (XRD) peaks corresponding to the monoclinic phase and and also the antisymmetric (834 cm) and symmetric stretching (715 cm) of tetrahedral VO and D (1330 cm) and G (1570 cm) bands corresponding to in the Raman spectrum. The worm-like structures of nanocrystals grew onto the lamellar sheets of , as shown by field emission scanning electron microscopy (FESEM), and has an increased surface area of 15.

Factors Influencing Monkeypox Vaccination: A Cue to Policy Implementation.

Background: Following the mpox 2022 outbreak, several high-income countries have developed plans with inclusion criteria for vaccination against the mpox disease. This study was carried out to map the factors influencing mpox vaccination uptake to help address the challenges and increase vaccination confidence.

Methods: This was a study based on Tweet analysis.

Electric and Magnetic Tuning of Gilbert Damping Constant in LSMO/PMN-PT(011) Heterostructure.

Electric field control of magnetodynamics in magnetoelectric (ME) heterostructures has been the subject of recent interest due to its fundamental complexity and promising applications in room temperature devices. The present work focuses on the tuning of magnetodynamic parameters of epitaxially grown ferromagnetic (FM) LaSrMnO(LSMO) on a ferro(piezo)electric (FE) Pb(MgNb)O-PbTiO(PMN-PT) single crystal substrate. The uniaxial magnetic anisotropy of LSMO on PMN-PT confirms the ME coupling at the FM/FE heterointerface.

A sentiment and content analysis of tweets on monkeypox stigma among the LGBTQ+ community: A cue to risk communication plan.

Background: The stigma associated with monkeypox (mpox) may prevent people from following recommended guidelines. Using a "model of stigma communication," this study maps and determines the mpox stigma on Twitter among LGBTQ+ (Lesbian, gay, bisexual, transgender, queer and more) community.

Methods: The tweets that contained the terms '#monkeypox', '#MPVS', '#stigma', and '#LGBTQ+' and were published between May 01, 2022 and Sept 07, 2022 were extracted.

Clinical Considerations: 9 clinicians and 6 resource persons from dental colleges in India collaborated in this consensus statement which covered 6 topics along with 6 introductory and 6 conclusive remarks.

Rapid Genomic Evolution Drives the Diversification of Male Reproductive Genes in Dung Beetles.

The molecular basis for the evolution of novel phenotypes is a central question in evolutionary biology. In recent years, dung beetles have emerged as models for novel trait evolution as they possess distinct precopulatory traits such as sexually dimorphic horns on their head and thorax. Here, we use functional and evolutionary genomics to investigate the origins and the evolution of postcopulatory reproductive traits in male dung beetles.

Female spider aggression is associated with genetic underpinnings of the nervous system and immune response to pathogens.

Identifying the genetic architecture underlying phenotypic variation in natural populations and assessing the consequences of polymorphisms for individual fitness are fundamental goals in evolutionary and molecular ecology. Consistent between-individual differences in behaviour have been documented for a variety of taxa. Dissecting the genetic basis of such behavioural differences is however a challenging endeavour.

Metal-free propargylation/aza-annulation approach to substituted β-carbolines and evaluation of their photophysical properties.

An efficient acid-catalyzed propargylation/aza-annulation sequence was developed under metal-free reaction conditions, thus leading to a one-pot synthesis of a variety of substituted β-carbolines starting from propargylic alcohols and indole 2-carbonyls. This versatile strategy was further extended to the synthesis of 5-azaindoles and 5-azabenzothiazoles. Optical properties suggested that manipulation of electron donor and acceptor moieties on β-carbolines has an impact on their ground and excited state electronic behavior.

Today's solar cells are exceptionally in demand whilst excess exploitation of natural fossil fuels. In this context, the first and second generation solar cells commercially available in market for more than decades however limitations in production cost and large-scale applications insist to generate inexpensive materials for fabrication. Thereby, organic materials based solar cells explored and emerging as third generation solar cells which possess flexibility, low cost and large-scale applications.

Adaptive evolution of distinct prey-specific toxin genes in rear-fanged snake venom.

Venom proteins evolve rapidly, and as a trophic adaptation are excellent models for predator-prey evolutionary studies. The key to a deeper understanding of venom evolution is an integrated approach, combining prey assays with analysis of venom gene expression and venom phenotype. Here, we use such an approach to study venom evolution in the Amazon puffing snake, , a generalist feeder.
