In Vitro Effects of Combining Resin Infiltration and At‐Home Bleaching on Hydrogen Peroxide Penetration, Color Change and Enamel Morphology

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of resin infiltration (RI) prior to at‐home bleaching on hydrogen peroxide (HP) penetration into the pulp chamber, color change, and enamel morphology in human teeth with sound enamel or white spot lesions (WSLs), using different RI protocols.

6‐Month Clinical Evaluation of Reduced Dentin Etching Time Using Universal Adhesives in Noncarious Cervical Lesions: A Double‐Blind Randomized Clinical Trial

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effect of reduced dentin etching time on the clinical performance of two universal adhesive systems in noncarious cervical lesions (NCCLs). Methods A total of 144 NCCLs restorations were randomly placed in 36 participants according to four experimental groups: SUP5 (Scotchbond Universal Plus adhesive [pH ≈2.5–2.7 ...

Application of Baicalein Solution as a Novel Antioxidant After Bleaching: Analysis of Its Effects on Immediate Color Stability and the Reestablishment of Bond Strength in Bleached Enamel

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the antioxidant capacity of the baicalein solution (BA), as well as its effect when applied for different times to the surface of bleached dental enamel, considering immediate color stability and bond strength. Materials and Methods Bovine enamel/dentin specimens (4 × 4 × 3 mm) were randomly divided into five groups (n ...

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

open access: yesJournal 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.

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

open access: yesJournal 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

open access: yesMedical 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.

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

open access: yesScience 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

‘In Curaçao They Celebrate King's Day Abundantly!’ – Diachronic Representation of (Post)colonial Communities in Dutch Geography Textbook Discourse (1946–2018)

open access: yesTijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract Postcolonial textbook research leads us to reflect on the representation of (post)colonial communities in educational media for adolescents in geography education. This paper contributes to this scholarship through Critical Discourse Analysis tracing how nine Dutch geography textbooks (1946–2018) have represented such communities from ...
