In vitro bond strength of cements to treated teeth

Abstract

Adhesive bond strengths of glass ionomer and polycarboxylate cements to human enamel and dentine were measured in vitro on untreated surfaces and on surfaces treated with cement liquid or polyacrylic acid, ferric oxalate, and ferric chloride. The bond strengths of two cements to enamel and dentine were increased by as much as 183 per cent by the use of surface treatments of polyacrylic acid and ferric oxalate.

Repair of composites: Effect of laser and different surface treatments

“…A Teflon device was used to fabricate an inverted truncated cone of repair composite over the surface-treated top of each original aged truncated cone, using incremental applications of Filtek Z350, with each layer polymerized separately for 20 s. The final specimen consisted of two inverted truncated cones of resin composites united by their circular top surfaces where the repair was made [20,21] (Fig. 1).…”

Influence of Ankaferd Blood Stopper on shear bond strength of bonding systems

“…Blood contamination reduces resin/dentin bond strength significantly more so than salivary contamination 4) . The influence of blood contamination on bond strength can be attributed to its high protein content which, along with macromolecules such as fibrinogen and platelets, can form a film on the dentine surface, obstructing the penetration of the adhesive system into dentine tubules 1,5) . Clinical and in vivo studies have been reported discussing various haemostatic agents used for the management of hemorrhage in clinical dentistry, such as hydrogen peroxide (H2O2), ferric sulfate, aluminum chloride, trichloracetic acid and Ankaferd Blood Stopper (ABS) (Ankaferd Drug INC, Istanbul, Turkey) [6][7][8][9][10] .…”

Bond Strength to Enamel

“…Two popular tensile bond tests include the inverted, truncated cone test (Fig. 3.1) [2] and the microtensile test ( Fig. 3.2) [3].…”
