Different superscript letters in column indicate statistically significantly different groups (). IB: immediately bonding; DB: delayed bonding. Subgroup SA 3 m, SA 5 m, SA 10 m, SA 30 m, SA 1 h, SA 24 h, SA 48 h, and SA 72 h were applied to 10% sodium ascorbate (SA) solution for 3, 5, 10, and 30 minutes and 1, 24, 48, and 72 hours, respectively, before bonding procedure.
