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 .
Three-year clinical evaluation of the Clearfil Liner Bond system.
Modern dental adhesive systems have improved the bond of restorative material s to mineralized tooth structures . The purpose of this study was to evaluate the clinical performance of composite restorations placed in abrasion and erosion lesions using the Clearfil Liner Bond dental adhesive system . Following ADA clinical guidelines for dentin and enamel adhesive material s , 62 facial class 5 smooth surface erosion or abrasion lesions with no undercuts and involving primarily root surfaces were restored in 25 adult male and female patients . The teeth were restored without preparations using Clearfil Liner Bond and Clearfil Photo Anterior composite resin . The clinical performance of the restorations was assessed by two examiners at baseline , 6 months , 1 , 2 , and 3 years using the following evaluative parameters : color match , marginal discoloration , and marginal integrity according to modified Ryge criteria ; the presence or absence of recurrent decay ; pre- and postoperative sensitivity ; and restoration failure due to loss of retention or other causes . At the end of 3 years , four of the 55 restorations remaining in the study failed due to lack of retention ( 92.7 % retention rate ) . The evaluations of the other clinical parameters demonstrated excellent performance by this system
