Acrylophosphonic acid reactivity with calcium ions and biological apatite

HEMA reactivity with demineralized dentin

“…The impact of HEMA is clearly different from that of reactive monomers at the resin-dentine interface. 27 r e f e r e n c e s…”

Modifications of the organic and mineral fractions of dental tissues following conditioning by self-etching adhesives

“…9 In a previous report, we showed that a phosphonomethacrylate monomer reacted with dental HA by forming a sparingly soluble phosphonoacrylate calcium salt and forming a calcium hydrogenophosphate of lower Ca/P ratio than that of HA. 23,24 Our objective was to analyse the acid strengths and concentrations in contemporary self-etch adhesives and test whether the A/D concept functions the same way for all products. It was anticipated that some hydrophobic monomers would adhere to HA with minimal dissolution of calcium.…”

Depletion of water molecules during ethanol wet-bonding with etch and rinse dental adhesives

“…The strong peak at 3.5 ppm was attributed to the phosphate groups in dental hydroxyapatite whereas the small peak at 24.01 ppm was related to the phosphorous atom present in the phosphonate group of the adhesive. It did not change with or without the ethanol rinse [8,9].…”
