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 .
Five-year clinical evaluation of two adhesive systems in non-carious cervical lesions.
OBJECTIVE This controlled clinical trial evaluated the 5-year clinical performance of a self-etching primer system including selective enamel-etching with phosphoric acid and a one-bottle adhesive system . METHODS Seventy-two non-carious cervical lesions in 8 patients ( 4 male and 4 female ) with a mean age of 61.3 years ( range 45 - 78 ) participated in the study . An enamel bevel was placed and dentin lightly ground , and cavities restored with clearfil liner bond II ( LB ) or single bond ( SB ) in conjunction with a hybrid resin composite ( Clearfil AP-X ) . In the case of 27 cavities for LB , the enamel was pretreated with 37 % phosphoric acid for 10 s. Each patient received both types of restoration , which were distributed on a r and om basis . All restorations ( 37 restorations for LB and 35 restorations for SB ) were placed by one dentist . The restorations were evaluated blind after 5 years using modified USPHS criteria . The data were statistically analyzed using the Fisher 's exact test . RESULTS All but one restoration ( which was replaced by a crown after the 2-year recall ) were evaluated after 5 years . 100 % retention rates were recorded for both restorative groups . No caries was detected in association with any restorations . The only minor problem was marginal discoloration ; superficial and localized marginal discoloration occurred around 18 % of the restorations , and mainly at the dentin margin . There were no significant differences in the marginal integrity between the LB and SB groups . CONCLUSIONS Restorative material s used in this study demonstrated a good clinical effectiveness in the restoration of non-carious cervical lesions for 5 years
