The efficacy of ball blankets on insomnia in depression in outpatient clinics: A randomised crossover multicentre trial.

Many patients with depression report insomnia symptoms that profoundly affect their health and well-being. Non-pharmacological treatments of insomnia may be preferable for some patients. In this randomised crossover trial, we investigated the efficacy of the Protac Ball Blanket® on insomnia among patients with depression.

Effect of preheating and shade on surface microhardness of silorane-based composites.

Aim: The aim of the present study was to evaluate the effect of preheating and shade on the surface microhardness of silorane-based composites.

Methods: Three shades of two different types of composites were evaluated: a silorane-based composite and a methacrylate-based composite. The composites were tested at 23°C, and after preheating at 55°C.

The reparability of contemporary composite resins.

Objective: The objective was to investigate the way that various surface treatments could influence the bond strength of the repair of methacrylate (MC) and silorane (SIL) composites.

Materials And Methods: A total of 160 MC and SIL cylindrical specimens were polymerized and aged in artificial saliva solution for 7 days. Depending on the following surface treatment (diamond bur or air abrasion), and the conditioning procedure (orthophosphoric acid or sodium hypochlorite), 16 groups were formed and repaired either with MC, either with SIL composite.

Bonding of adhesives to Er:YAG laser-treated dentin.

Objective: The shear bond strength of adhesives applied to dentin was investigated after irradiation with an erbium-doped yttrium aluminum garnet (Er:YAG) laser.

Methods: Superficial and deep dentin specimens from human molars were treated either with carbide bur or an Er:YAG laser. Two etch and rinse adhesives (Single Bond and XP Bond) and two self-etch adhesives (Prompt L-Pop and Xeno III) were employed to bond the composite.

Dynamic and static elastic moduli of packable and flowable composite resins and their development after initial photo curing.

Objective: The purpose of this study was to evaluate the dynamic (storage) shear modulus and the static shear modulus of elasticity of packable and flowable composite resins and to investigate their development after initial photo-curing.

Methods: Three pairs of a packable versus a flowable composite and a microfill composite resin were tested (Alert/Flow It, Filtek P60/Filtek Flow, Admira/Admira Flow, A 110). Cylindrical specimens (0.
