Carbon fibre plates (20 x 5 mm) were characterised by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray-induced photoelectron spectroscopy (XPS). The 90 degrees peeling test was used (0.5 mm s(-1)) at the carbon fibre Panavia F-(R) interface. The fracture interfaces were analysed using both SEM and EDS....

The aim of this study was to finalise a 90° peeling test on 60 human teeth. The dentinal surfaces to be stuck were characterised by micro-hardness, wettability, optical microscopy, SEM, AFM, XPS and EDS. The so-called fifth-generation bonding agent (Prime & Bond(®) 2.1 DeTrey Dentsply) was used to perform the peeling-test. The extremity of a...

The aim of this study is to determine the influence of different characteristic parameters of the human dentine surface on the interaction between dentine and adhesive resin. The dentine surface of 21 freshly extracted teeth (from patients between the ages of 13 and 77 years old) was treated with Total Etch (Vivadent etching gel) and...

The main aim of this study was to determine the viscosity of four amelo-dentinal adhesives based on the same adhesion principles: the complete elimination of the dentinal smear layer using a 37% orthophosphoric acid and the building of a hybrid layer in a single stage. The secondary aim was to study the filling time for a tubulus using 2...

Objective: This study was conducted to study the role of pulpal pressure on the shear bond strength of composite resin bonded to Er:YAG laser-prepared or bur-prepared dentine surfaces using a self-etching adhesive system. Materials and Methods: The occlusal surfaces of 80 human third molars were ground flat to expose the dentine. The dentine...

This study was conducted to compare the shear bond strengths of composite resin bonded to Er:YAG laser or bur-prepared dentin surfaces using three self-etching adhesive systems. The occlusal surfaces of 120 human third molars were ground flat to expose dentin. The dentin was prepared using either a carbide bur or an Er:YAG laser at 350 mJ/pulse...
