چکیده
|
Previous research,in which the bonding effectiveness of the 3 self-etch monomers haepa,eaepa,and maepa was determined,showed that maepa was most effective. in this study,the molecular interactions of these monomers with hydroxyapatite and dentin were investigated by combining x-ray diffraction,infrared spectroscopy,and scanning electron microscopy. we tested the null hypothesis that the bonding performance of these monomers does not correlate to the formation of monomer-calcium salts and to hydrolytic stability of these monomer-calcium complexes. monomer/ ethanol/water solutions were prepared and applied to synthetic hydroxyapatite and dentin. while haepa and eaepa dissolved dentin considerably and deposited unstable calcium-phosphate salts (dcpd),maepa formed hydrolysis-resistant monomer-calcium salts that remained attached to the dentin surface even after being washed. the chemical stability of the monomer-ca salts was thought to contribute in particular to the bond durability,but this study shows that the formation of stable monomer-calcium salts also enhances the 'immediate' bonding performance of self-etch adhesives. © 2011 international & american associations for dental research.
