Conclusion The current best evidence indicates that a glass ionomer cement has a significantly lower risk of loss of a NCCL restoration compared to either a three-step etch- and -rinse or a two-step etch- and -rinse adhesive system ; a three-step etch- and -rinse adhesive system has a significantly lower risk of loss of a NCCL restoration compared to a two-step etch- and -rinse adhesive system .
No significant difference could be observed in the risk of loss of a tooth-colored NCCL restoration between a three-step etch- and -rinse adhesive system and either a two-step self-etch or a one-step self-etch adhesive system
Objectives The aim of this review was to assess the effect of different adhesive systems and tooth preparation on the retention of tooth-colored restorative material s  placed in non-carious cervical lesions ( NCCLs ) .
Clinical performance of a resin-modified glass-ionomer and a compomer in restoring non-carious cervical lesions. 5-year results.
PURPOSE To evaluate the 5-yr clinical performance of a resin-modified glass-ionomer cement and a polyacid-modified resin composite in restoring non-carious cervical lesions . MATERIAL S AND METHODS Non-carious cervical lesions in 46 incisors , canines , and premolars were restored either with Fuji II LC  ( n=18 ) or with  Dyract ( n=28 ) in 16 healthy patients . The lesions were restored without cavity preparation strictly according to the manufacturer 's instructions . The restorations were clinical ly evaluated single blind after 5 yrs using modified USPHS criteria . RESULTS The percentage of Alfa ratings were as follows ( Dyract/Fuji II LC ) : color match 81.3%/28.6 % , surface texture 93.8%/21.4 % , anatomic form 75.0%/28.6 % , marginal integrity ( enamel ) 62.5%/42.9 % , marginal integrity ( dentin ) 68.8%/28.6 % , marginal discoloration ( enamel ) 56.3%/42.9 % , marginal discoloration ( dentin ) 68.8%/21.5 % . Five-yr data revealed a significant difference between the clinical ratings of Dyract and Fuji II LC for all criteria except marginal integrity and marginal discoloration in enamel . A total of five Dyract restorations and four Fuji II LC restorations failed within the study period . CLINICAL SIGNIFICANCE A considerably high and almost similar overall failure rate was found for both restorative material s in restoring non-carious cervical lesions . However , retained Dyract restorations presented superior clinical performance compared to Fuji II LC restorations
Conclusion The current best evidence indicates that a glass ionomer cement has a significantly lower risk of loss of a NCCL restoration compared to either a three-step etch- and -rinse or a two-step etch- and -rinse adhesive system ; a three-step etch- and -rinse adhesive system has a significantly lower risk of loss of a NCCL restoration compared to a two-step etch- and -rinse adhesive system .
