Combination of EDTA conditioner and Phenyl-P/HEMA self-etching Primer for bonding to dentin

摘要

Objectives: The purpose of this study was t examine a new bonding system, combining an ethylenediamineteraacetic acid (EDTA) conditioner and the 2-methacryloyloxyethyl phenyl phosphoric acid (Phenyl-P)/2-hydroxyethyl methacrylate (HEMA) self-etchingprimer with a dumbbell-shaped specimen for tensile test. Methods: Bovine dentin was prepared with a 180-grit paper, conditioned with EDTA, primed with Phenyl-P/HEMA and applied with a Light-cured bonding agent, then trimmed to the dumbbell-shaped specimen.
