Faulty bond strength measurements? -

The most commonly used bonding stress method for testing adhesives and cement, the thermal cycling, jeopardizes the results if not done with caution. This leads to a more favorable bond strength than the true value.

Bond strength between dentine and a novel fast-setting calcium silicate cement with fluoride -

The aim of this study was to evaluate the dentine bond strength of a novel fast‐setting calcium silicate cement (Protooth) versus a calcium hydroxide‐based cement (Dycal), a calcium silicate cement (ProRoot MTA), and a glass ionomer cement (Ketac‐Molar). Mid‐root dentine slices of 1 mm thickness were obtained from human maxillary incisors. After enlarging the lumen […]

Bonding of Composite and Glass-ionomer to Amalgam -

Amalgam restorations of adequate standard and condition can very well be repaired with composite, but there should be provided for extra retention into the amalgam filling as the bond strength alone is not adequate. Glass-Ionomer may also be used for repair at amalgam restoration margins in not stress bearing areas, but as they do not adhere to amalgam, they need enamel and dentine for retention and possible undercuts towards amalgam interface.

The effects of EDTA and iodine-potassium iodide on the adhesion properties of root filling materials -

The effects of dentin pre-treatment with ethylene diamine tetraacetic acid (EDTA) or iodine-potassium iodide (IKI) on the adhesion of a conventional root filling material (gutta-percha and epoxy resin based sealer) and an acrylic-resin-based system with adhesive technology were studied.

Bond strength of luting materials to ceramic crowns after different surface treatments. -

The aim of present study was to evaluate the effect of different pre-treatments of alumina and zirconia copings on the bond strength of different luting materials. Pull out tests was performed on 60 alumina and 80 zirconia copings.
