Dry-bonding to dentin using alternative conditioners based on iron-containing solutions or nitric acid

To evaluate the effect of experimental conditioners (10–3 solution − 10–3, 6.8% ferric oxalate - FOX, and 1.4% nitric acid - NI) on dentin elastic modulus, flexural strength, bond strength, failure mode, and adhesive interface morphology of two etch-and-rinse adhesives (XP Bond, Dentsply or One-Step, Bisco) applied on etched dry dentin. Sound human third molars were used for the microtensile bond strength test (n = 8), performed at 24 h and...
