Objective: To evaluate the shear bond strength (SBS) and adhesive remnant index (ARI) scores of metal brackets to glazed lithium disilicate reinforced glass-ceramics and zirconia according to various surface treatment protocols.

Methods: A total of 240 lithium disilicate ceramic (LD) and 240 zirconia (Zr) blocks were randomly divided according to sandblasting, hydrofluoric acid (HF) etching, universal primer use, and the adhesive system applied. A maxillary canine metal bracket was bonded to each sample with resin cement (Transbond XT, TXT).

KIRA6 is an Effective and Versatile Mast Cell Inhibitor of IgE-mediated Activation.

Mast cell (MC)-driven allergic diseases are constantly expanding and require the development of novel pharmacological MC stabilizers. Allergen/antigen (Ag)-triggered activation via crosslinking of the high-affinity receptor for IgE (FcεRI) is fundamentally regulated by SRC family kinases, for example, LYN and FYN, exhibiting positive and negative functions. We report that KIRA6, an inhibitor for the endoplasmic reticulum stress sensor IRE1α, suppresses IgE-mediated MC activation by inhibiting both LYN and FYN.

Gingival Proliferative Verrucous Leukoplakia and Cancer: A Systematic Review With Meta-Analysis.

Objective: Proliferative verrucous leukoplakia (PVL) is an oral potentially malignant disorder. Forms that affect only one tissue are poorly studied, especially the exclusively gingival PVL (gPVL), which may have a more increased malignant transformation potential. The aim of the present study was to characterise the gPVL and its risk of malignant transformation to better raise awareness of this specific disorder.

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

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.

Advanced Material Strategy for Restoring Damaged Endodontically Treated Teeth: A Comprehensive Review.

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.

Pharmacokinetics and pharmacodynamics of drug‒drug interactions in hospitalized older adults treated with direct oral anticoagulants.

Purpose: Polypharmacy is a frequent situation in older adults that increases the risk of drug-drug interactions (DDIs), both pharmacokinetic (PK) and pharmacodynamic (PD). Direct oral anticoagulants (DOACs) are frequently prescribed in older adults, mainly because of the high prevalence of atrial fibrillation (AF). DOACs are subject to cytochrome P450 3A4 (CYP3A4)- and/or P-glycoprotein (P-gp)-mediated PK DDIs and PD DDIs when co-administered with drugs that interfere with platelet function.

Engaging student analysis of the practitioner-patient relationship assessed with reflective outcomes.

The representations and beliefs of both patient and practitioner influence the relationship that develops between them. We developed an innovative, interactive teaching tool in two stages (1- interviews with the patient or healthcare practitioner and 2- a session with sharing of the patient's and practitioner's perspective) whose objectives are to recognize the basic characteristics of PPR and identify how it can be influenced by expectations, beliefs and emotions. This pedagogical device was particularly appreciated by the students, as it enabled them to identify the importance of the patient's point of view and to reflect on their future professional identity.

Touch-cure activation by marketed universal resin luting cements of their associated primer to dentin.

Purpose: The aim of this study was to investigate the dentin shear bond strength (SBS) and bonding interface of three recently developed "universal" resin luting cements based on different modalities.

Methods: The dentin SBS and interfacial analysis of three recently launched "universal" resin luting cements, namely, G-Cem One, RelyX Universal and Panavia SA cement universal, were studied. All bonding protocols, including the previous use of their dedicated primer or universal adhesive in touch-cure mode or light-cure mode were performed.

SR-BI regulates the synergistic mast cell response by modulating the plasma membrane-associated cholesterol pool.

The high-affinity IgE receptor FcεRI is the mast cell (MC) receptor responsible for the involvement of MCs in IgE-associated allergic disorders. Activation of the FcεRI is achieved via crosslinking by multivalent antigen (Ag) recognized by IgE resulting in degranulation and proinflammatory cytokine production. In comparison to the T- and B-cell receptor complexes, for which several co-receptors orchestrating the initial signaling events have been described, information is scarce about FcεRI-associated proteins.

Analysis of Resin-Based Dental Materials' Composition Depending on Their Clinical Applications.

The objective of this study was to detail the monomer composition of resin-based dental materials sold in the market in 2023 and to evaluate the proportion of bisphenol A (BPA)-derivatives in relation to their applications. A search on manufacturers' websites was performed to reference resin-based dental materials currently on the European market (including the European Union (EU) and United Kingdom (UK). Their monomer composition was determined using material-safety data sheets and was completed by a search on the PubMed database.

Proliferative Verrucous Leukoplakia Presenting as a Ring Around the Collar and Cancer: A Case Report.

Proliferative verrucous leukoplakia (PVL) is an oral mucosa lesion with a high rate of malignant transformation. The diagnosis is often difficult, especially when the initial lesion is a simple homogeneous white leukoplakia, and when located only on the gingiva or palate. Moreover, the anatomopathological analysis is non-specific in the initial stages.
