Abstract:
Objective To evaluate the shear bend strengths of four dental adhesives in vitro.Methods The facial surfaces of 20 human maxillary incisors were prepared to expose fresh enamel and randomly divided into four groups, in each group 5 teeth were bonded with one adhesives: group A (ClearfilTM Protect Bond, serf-etching two steps), group B (AdperTM PromptTM, self-etching one step), group C (SwissTEC SL Bond, total-etching two steps), group D (Single Bond, total-etching two steps).Shear bend strengths were determined using an universal testing machine after being stored in distilled water for 24 h at 37 ℃.Results The bond strengths to enamel and dentin were (25.33±2.84) and (26.07±5.56) MPain group A,(17.08±5.13) and (17.93±4.70) MPa in group B,(33.14±6.05) and (41.92±6.25) MPa in group C, (22.51±6.25) and (21.45±7.34) MPa in group D.Group C showed the highest and group B the lowest shear bond strength to enamel and dentin among the four groups.Conclusions The two-step self-etching adhesive showed comparable shear bend strength to some of the total-etching adhesives and higher shear bend strength than one-step self-etching adhesive.
