Strength evaluation of scarf joints bonded with adhesive resin.

Strength of Composite Scarf Joints

In recent years, large composite structures have been used increasingly in the aerospace and naval industries. Such a large composite structure is mostly fabricated using the scarf joining technique so that multiple substructures can be connected together. Figure 1 shows three commonly used scarf joint configuration. Among the three, the step/overlap joint is considered as the strongest because...

Bond strength of adhesive resin cement with different adhesive systems

BACKGROUND To assess the immediate bond strength of a dual-cure adhesive resin cement to the hybridized dentin with different bonding systems. MATERIAL AND METHODS Fifty-six healthy human molars were randomly divided into 7 groups (n=8). After 3 longitudinal sections, the central cuts were included in PVC matrix and were submitted to dentin hybridization according to the groups: G1 - etch & r...

Reliability analysis of bonded joints with variations in adhesive thickness

Evaluation 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...

Shear bond strength evaluation of resin composite to resin-modified glass-ionomer cement using three different resin adhesives vs. glass-ionomer based adhesive

Background: The clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (RMGIC) bonding to both dentin and resin composite. Therefore, the shear bond strength (SBS) of resin composite bonded to RMGIC utilizing different resin adhesives versus a GIC-based adhesive was compared. Materials and methods: In this in vitro study, 84 holes (5×2 mm) were pre...
