Effectiveness of sodium hypochlorite and sulfinic acid sodium salt treatment on dentin-resin bonding : Long-term durability of one-step self-etching adhesive

This study aimed to evaluate the effect of sulfinic acid sodium salt interposition after acid and sodium hypochlorite treatment (NC treatment) on dentin bonding durability using a mild type one-step self-etching adhesive. Fifteen human third molars were randomly assigned into three experimental groups according to dentin pretreatment before applying the one-step self-etching adhesive: Cont group, without pretreatment; NC group, pretreatment with phosphoric acid and sodium hypochlorite gel; and NC+AC group, additional treatment with sulfinic acid sodium salt followed by the same pretreatment of the NC group. Microtensile bond strength was measured and the pre-treated dentin surface, fracture modes, and bonding interface were observed. The bond strength of the NC+AC group was significantly higher than that of the other groups (p<0.001). The dentin-adhesive interface was degraded after 1 year only in the Cont group. Our results demonstrated NC treatment improves bonding durability and application of sodium sulfinic acid salt after NC treatment improves bonding effectiveness.
