Adhesive bonding of various materials to hard tooth tissues. XV. Neutron activation analysis of dentin sorption of mordant salts

R. L. Bowen, L. T. McClendon and T. E. Gills

Five metallic chlorides were compared simultaneously, with regard to their interaction with dentin surfaces. Neutron activation analysis was used to measure the quantities absorbed. Each metal was bound by dentin to some extent during a 60-second exposure, and was not removed during a 20-second rinse with distilled water. Quantitatively, the gram-atom amounts of ions sorbed increased in the order Co less than Al less than Zn approximately Cu less than Fe. These mordant salts warrant further study as a possible means of improving adhesive bonding between dental resins (via polyfunctional surface-active comonomers) and dentin.
