Abstract
Objectives: To evaluate the effect of different irrigation times of 10% sodium
ascorbate on microshear bond strengths of two adhesives: Adper™ Single
Bond 2 and Clearfil SE Bond, to enamel bleached with 10% carbamide
peroxide.
Materials and methods: Sixty sound human premolars were divided into 5
groups regarding to treatment of facial enamel surfaces: 1 no treatment
(unbleached enamel), 2 bleached with 10% carbamide peroxide (VivaStyle
10%), the other three groups were bleached and followed by irrigation with
10% sodium ascorbate for 30 sec, 1 min and 10 min respectively. Enamel
surface of all specimens were bonded with one of the two adhesives and
then restored with a resin composite. The microshear bond strength testing
was performed using a universal testing machine at a crosshead speed of 1
mm/min after storage in distilled water at 37°C for 24 hours. The data were
analyzed using two-way ANOVA and post-hoc multiple range test (p<0.05).
Results: Irrigation with sodium ascorbate for 10 min could reverse the bond
strength of bleached enamel in group using AdperTM Single Bond 2 to the
same level as that of the control group (p<0.05). However, irrigation with
sodium ascorbate had no effect on the bond strength of bleached enamel
bonded with Clearfil SE Bond.
Conclusion: Pretreatment with sodium ascorbate for 10 min before
composite restoration improved the bond strengths of bleached enamel
when AdperTM Single Bond 2 was used.
