To evaluate the effect of a dentin adhesive on sclerotie dentin, contraetion gap width and shear bond strength were measured, Dent{n cavity wall was pretreated with an experimental dentin bonding system w{th and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was signifieantly smaller than that of sound dentin whon the cavity wns not primed with glyeeryl monomethacrylatc.

Contraction gap versus shear bond strength of dentin adhesive in sound and sclerotic dentins.
To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding system with and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was significantly smaller than ...

متن کاملEvaluation of the effect of two different desensitizing agents on shear bond strength of universal adhesive resin (an invitro study )
Background and Aim: dentin desensitizers may affect dentin organic matrix properties or occlude dentinal tubules which may have adverse effects on the bonding performance of adhesive systems. The aim of this study was invitro evaluation of Gluma desensitizer and Tokuyama Shield Plus effects or shear bond strength of (BISCO) all-bond universal bonding system. Materials and Methods: 30 caries f...
متن کاملShear bond strength of different adhesive systems to normal and caries-affected dentin
BACKGROUND AND AIM: According to the effect of the adhesive and substrate type on the bond strength, examination of the adhesive is required in all aspects. The aim of this study was to evaluate the shear bond strength of different adhesive systems to normal dentin (ND) and caries affected dentin (CAD) in permanent teeth. METHODS: Thirty extracted molars with small occlusal caries were selected...
