This study investigated the effect of SnCl/AmF pretreatment on short- and long-term bond strength of resin composite to eroded dentin mediated by two self-etch, MDP-containing adhesive systems. 184 dentin specimens were produced from extracted human molars. Half the specimens ( = 92) were artificially eroded, and half were left untreated. For both substrates, half the specimens were pretreated with SnCl/AmF, and half were left untreated. The specimens were treated with Clearfil SE Bond or Scotchbond Universal prior to application of resin composite. Microtensile bond strength (TBS) was measured after 24 h or 1 year. Failure mode was detected and EDX was performed. TBS results were statistically analyzed ( = 0.05). TBS was significantly influenced by the dentin substrate (eroded < noneroded dentin) and storage time (24 h > 1 year; < 0.0001) but not by pretreatment with SnCl/AmF or adhesive system. The predominant failure mode was adhesive failure at the dentin-adhesive interface. The content of Sn was generally below detection limit. Pretreatment with SnCl/AmF did not influence short- and long-term bond strength to eroded dentin. Bond strength was reduced after storage for one year, was lower to eroded dentin than to noneroded dentin, and was similar for the two adhesive systems.
