Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Air‐Abrasion With Aluminum Oxide Particles in Non‐Carious Cervical Lesions: Impact on Sclerotic Superficial Layer, Surface Topography, and Restorative Adhesive Performance

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of airborne‐particle abrasion (APA) with aluminum oxide on superficial dentin sclerosis, surface topography, and bonding performance of a universal adhesive in natural non‐carious cervical lesions (NCCLs), using dentin classification by the North Carolina Index (NCI) and Optical Coherence Tomography Index (OCT).

Translucency Changes of Ceramic Veneers After Aging When Cemented on Substrates With Different Saturation: Effect of Ceramic Translucency and Resin Cement Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of ceramic translucency and resin cement shade on the translucency alteration after aging over different substrates. Methods Sixty specimens were divided into 12 groups (n = 5) composed of lithium disilicate (IPS e.max CAD, Ivoclar Vivadent) in three translucencies (HT, MT, LT).

Effect of Silane Incorporation on the Bonding Performance of Universal Adhesives to Dentin

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Purpose The effect of silane in universal adhesives (UAs) on dentin adhesion remains unclear. Therefore, this study evaluated the dentin bonding of UAs with and without silane immediately and after thermocycling. Materials and Methods Sixty‐four sound human molars were randomly assigned to eight groups according to silane incorporation (UAs ...

Effectiveness of self‐etching ceramic primer on the bond strength of dental glass ceramics: A systematic review and meta‐analysis of in vitro studies on feldspathic and leucite‐reinforced ceramics

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review and meta‐analysis evaluated the bond strength effectiveness of a self‐etching ceramic primer, specifically Monobond Etch & Prime (MEP), compared to hydrofluoric acid with silane (HF+S) in feldspathic and leucite‐reinforced dental glass‐ceramics (DGCs). Materials and Methods This study followed PRISMA‐p guidelines

When I say… sexual misconduct

Medical Education, EarlyView.
Abstract In this ‘When I say …’ article, the authors argue for a conceptual shift in how health professions education understands and responds to sexual misconduct. We contend that sexual misconduct is frequently narrowly defined, individualised and downplayed in ways that obscure its systemic nature and limit meaningful action.

Evaluation of Maxillary and Mandibular Transverse Dimensions on Digital Models and CBCT in Untreated Subjects With Normal Occlusion

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives To evaluate the transverse dimension in adults with normal occlusion using cone‐beam computed tomography (CBCT) and digital models, and to establish norms for maxillo‐mandibular differentials. Material and Methods Twenty‐four untreated adults with normal occlusion were selected.

A semi-analytical three-dimensional free vibration analysis of functionally graded curved panels integrated with piezoelectric layers

Science and Engineering of Composite Materials, 2014
Free vibration analysis of functionally graded (FG) curved panels integrated with piezoelectric layers under various boundary conditions is studied. A panel with two opposite edges is simply supported, and arbitrary boundary conditions at the other edges
