RESULTS Comparison of retention of class-V adhesive restorations as a measure to determine clinical bonding effectiveness of adhesives revealed that glass-ionomers most effectively and durably bond to tooth tissue .
Three-step etch- and -rinse adhesives and two-step self-etch adhesives showed a clinical ly reliable and predictably good clinical performance .
The clinical effectiveness of two-step etch- and -rinse adhesives was less favourable , while an inefficient clinical performance was noted for the one-step self-etch adhesives .
SIGNIFICANCE Although there is a tendency towards adhesives with simplified application procedures , simplification so far appears to induce loss of effectiveness .
OBJECTIVES The purpose of this paper was to review current literature on the clinical effectiveness of contemporary adhesives when used to restore cervical non-carious class-V lesions .
Restoration retention in function of time was recorded in order to find out if adhesives with a simplified application procedure are as clinical ly effective as conventional three-step adhesives .
Eighteen-month clinical evaluation of a filled and unfilled dentin adhesive.
OBJECTIVE The purpose of this study was to evaluate the performance of a filled ( OptiBond Solo ) and an unfilled ( Prime & Bond 2.1 ) " one-bottle " adhesive in Class V restorations after 18 months of clinical service . METHODS Thirty-three patients with non-carious cervical lesions were enrolled in the study . A total of 101 lesions were restored using one of the adhesives and a hybrid composite resin . Enamel was not beveled , nor was any mechanical retention placed . The restorations were evaluated at baseline , and at 6 and 18 months after placement using modified USPHS criteria . RESULTS Cumulative 18-month retention rates were 93.6 % for OptiBond Solo and 98.0 % for Prime & Bond 2.1 . The difference in retention rates was not statistically significant . For OptiBond Solo , the only notable problems were interfacial staining and marginal adaptation , both of which were less than ideal in 9 % of restorations . Marginal problems were slightly less frequent for Prime & Bond 2.1 restorations , but the difference was not significant . CONCLUSIONS Both adhesives provided Class V retention rates exceeding the 18-month , full acceptance guidelines set by the American Dental Association . Any additional benefit provided by the use of a filled adhesive was not detected in this 18-month clinical trial
