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 .
Two-year clinical performance of Class V resin-modified glass-lonomer and resin composite restorations.
While a one-year report had been previously published , this study was undertaken to evaluate the clinical performance and appearance of a resin-modified glass ionomer and a resin composite over two years . Thirty-seven pairs of restorations of FujI II LC and Z 250/Single Bond were placed in caries-free cervical erosion/abfraction lesions without tooth preparation . Restorations were clinical ly evaluated at baseline , 6 , 12 , 18 and 24 months using modified Ryge/USPHS criteria . No statistically significant difference ( p = 0.13 ) was observed in the overall performance of the material s. Retention was 96 % for the resin-modified glass ionomer and 81 % for the resin composite , with no additional restorations of either material lost after one year . As previously reported , retention of the Z 250 restorations at six months was below the minimum specified in the ADA Acceptance Program for Dentin and Enamel Adhesives . The resin composite restorations generally had a better appearance , with a 100 % alpha rating in color match , versus 85 % for the resin-modified glass ionomer
