A randomized, controlled clinical trial of one-step self-etching adhesive systems in non-carious cervical lesions.
OBJECTIVE
To evaluate the clinical effectiveness of two different one-step self-etching adhesives.


METHODS
Two single-step self-etching adhesive systems, Clearfil Tri-S Bond and G-Bond, were evaluated. As a control, a two-step self-etching adhesive system, Clearfil SE Bond, was used. The teeth to be restored were randomly assigned. The resin composite used to restore the teeth was Clearfil AP-X. The three adhesive systems were evaluated by Modified USPHS at baseline, 3 months, 6 months, and 12 months. The evaluation consisted of retention rate, color match, marginal discoloration (interfacial staining), marginal adaptation (integrity), wear, post-operative sensitivity, caries recurrence, and other failures. Changes over time and across groups were evaluated statistically using generalized estimating equations.


RESULTS
During the 12-month study period, no statistical differences were observed among the three groups (P > 0.05) in retention rate, color match, marginal discoloration (interfacial staining), marginal adaptation (integrity). No wear, post-operative sensitivity, caries recurrence, or other failures were detected in any groups. The two one-step self-etching adhesives tested showed good clinical performance at the end of 12 months.
