Enamel bevel was prepared and dentin walls were lightly ground, and treated with S3Bond (S3: Kuraray Noritake Dental) or HEMA-free G-Bond (GB: GC) in conjunction with a hybrid resin composite (ClearfilAP-X: Kuraray Noritake) Respective subjects randomly received 1 to 4 restorations for each group. All restorations (53 restorations for S3 and 55 restorations for GB) were placed by one dentist. The restorations were blindly for S3 and 55 restorations for GB) were placed by one dentist. The restorations were blindly evaluated every year using modified USPHS criteria by two examiners. The data were statistically analyzed using the Fisher’s exact test, Kaplan-Meier method and Cox proportional hazards model.Results: Nineteen subjects were examined at 10-year recall. However, 25 restorations out of 33 unevaluated restorations at 10-year recall had already been rated Bravo or Charlie for retention failure, marginal adaptation, marginal discoloration, etc. Retention rates for S3 and GB were 95% and 97%, respectively. Secondary caries was detected adjacent to 1 restoration restored with GB. Four restorations were rated as unacceptable due to severe tooth wear. The main clinical problem was marginal discoloration at enamel margins. The incidence of marginal clinical problem was marginal discoloration at enamel margins. The incidence of marginal discoloration increased with time, and 10-year rates for S3 and GB were 65% and 79%, respectively. However, they were still superficial and clinically acceptable, except for one restoration. There was no significant difference in 10-year survival rates between adhesives (91% for GB and 94% for S3).Conclusions: No significant difference in the clinical performance was found between adhesives with and without HEMA.
