Microtensile bond strengths of glass ionomer (polyalkenoate) cements to dentine using four conditioners

Abstract

Objectives: The purpose of this study was to measure the microtensile bond strengths of three glass ionomer cements to dentine (Photac-Fil Quick; Fuji II LC; Fuji IX GP) using four different conditioners (Ketac Conditioner; Dentin Conditioner; Cavity Conditioner; and an experimental conditioner, K-930). Methods: Superficial occlusal dentine of extracted human third molars was exposed, finished with wet 600-grit silicon carbide paper, and each of the above glass ionomer cements bonded using the four conditioners according to the manufacturers' instructions. After 24 h in tap water at 37°C, the teeth were sectioned to obtain 3-4 bar-shaped specimens. Ten specimens were prepared for each group ..
