This in vitro study was designed to assess the shear peel bond strength and fracture pattern of

3 currently available compomers veneered to amalgam.

The purpose of this investigation was to determine the effect of hydrofluoric (HF) acid etchant on composite’s resin matrix.

Samples of 7 composite materials (Charisma, Herculite XR, Silux Plus, Z100, Prisma APH, Command, Perfection) and 7 unfilled

materials with similar resin components as the composites (Gluma, Scotchbond, Fortify, Delton, Sealite, Visar Seal, and Triad) were

allowed to complete their polymerization for an additional 24 hrs. at 37˚C following the recommended curing procedures. Knoop

The purpose of this study was to evaluate

quantitatively the effectiveness of adhesive dentin

bonding systems in decreasing microleakage at the

tooth-amalgam restoration interface. The results

indicated that microleakage was significantly reduced

when Amalgambond Plus or All-Bond 2

was used as liners in comparison to either

Copalite varnish or no liner under amalgam restorations.

No significant difference was found between

the two dentin bonding systems at all time

periods studied.
