Background: The Syrian conflict has had a negative impact on the psychological and overall health of adolescents. However, little is known about the oral health of those who are internally displaced.
Aims: The purpose of this study was to investigate the relationship between mental health state and self-reported oral health and habits in Syrian adolescents.
Objective: The objective of this study was to evaluate the resin-ceramic adhesion of a long-carbon-chain silane (LCSI)-containing resin cement.
Methods: Polished lithium disilicate ceramic discs were etched with hydrofluoric acid and randomly assigned into four groups; (PSAP), cemented using a silane-free resin cement with no prior priming; (PSAP-S), primed using a silane-containing primer before cementation using a silane-free resin cement; (PSAU), cemented using a LCSI-containing resin cement with no prior priming; (PSAU-S), primed as for the group (PSAP-S) and cemented using a LCSI-containing resin cement. The cemented blocks were sectioned into microbeams.
With the continuous development of adhesive technology leading to a wide variety of bonding systems in the market, clinicians are often faced with a vast number of systems to choose from. Although research and manufacture of bonding systems is constantly progressing, the focus has generally been on simplifying the bonding process by reducing the number of clinical steps, with little emphasis on evidence-based performance. This article draws attention to the current strategies of common commercially available products to guide clinicians during bonding system selection and application.

This study was conducted to develop and assess the performance of a two-step SE system using a functional monomer bis[2-(methacryloyloxy)ethyl]phosphate (BMEP) and demonstrate a strategy to enhance stability of bonded resin composite restorations to both enamel and dentine.
Methods: A two-step SE system was formulated with a primer containing BMEP, with an adhesive with or without BMEP, and compared to a commercial 10-MDP-containing system, Clearfil SE Bond 2 (CFSE).
Objective: The tooth-resin composite interface is frequently associated with failure because of microbial contamination, hydrolytic and collagenolytic degradation. Thus, designing a dentine bonding system (DBS) with an intrinsically antimicrobial polymerisable monomer is of significance especially if it can be used with self-etching primers enabling resistance to degradation of the interface.
Methods: Experimental adhesives were developed incorporating eugenyl methacrylate (EgMA) at concentrations of 0,10 or 20 wt%, designated as EgMA0, EgMA10 and EgMA20, respectively, for use as a two-step self-etch DBS with the functional monomer bis[2-(methacryloyloxy) ethyl] phosphate (BMEP) in the primer.
Objectives: The objectives were to investigate the hardness and chemical composition of sound, demineralized and pH-cycled bovine enamel and determine their influence on demineralization and remineralization behavior.
Methods: Ninety-four, 5 × 5 × 2-mm bovine enamel specimens were demineralized using three different times [(24 h (n = 33), 48 h (n = 30), 96 h (n = 31)]. The specimens were then pH-cycled using either 367 ppm F sodium fluoride or deionized water.
Aim: to explore the nature of leadership styles used by the nursing management team, as perceived by nurses working at the bedside.
Background: leadership style is related to job satisfaction, staff retention, costs, and quality of care. The leadership styles of managers can be crucial in the healthcare setting, but very few studies have focused on them.
