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 .
Cervical compomer restorations: the role of cavity etching in a 48-month clinical evaluation.
Compomers are defined as polyacid-modified resin composites . They are supposed to combine the advantages of traditional glass-ionomer cements with resin composites . This study clinical ly evaluated a compomer in cervical cavities . Sixty cervical cavities in premolars and molars ( 24 with cervical caries and 36 with abrasions ) r and omly divided into two groups of 30 teeth ( Group 1 and Group 2 ) were restored with Dyract  ( DeTrey-Dentsply , York , PA 17405 - 0872 ) . The cavities of Group 2 were etched for 30 seconds with orthophosphoric acid before compomer application , while the Group 1 cavities received no treatment . All the restorations were evaluated every six months , up to 48 months : characteristics assessed according to USPHS-modified st and ards were retention , secondary caries , post-operative sensitivity , marginal adaptation and discoloration , color and wear . The Kaplan-Meier 's survival analysis was performed . In both groups , retention was high without any statistically significant difference . No difference was found between the two groups for caries , post-operative sensitivity and wear -- that all had a low incidence . Color was not perfectly matched , however , there was no statistically significant difference between the two groups . Marginal discoloration and marginal adaptation loss were significantly higher in non-etched group ( p < 0.05 ) . Clinical ly relevant failure required 17.2 % of restorations in the non-etched group and 10 % in the etched group to be replaced : this difference was not statistically significant . Dyract has an acceptable clinical behavior when used in cervical cavities . Its marginal adaptation is enhanced by etching
