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 ) .
Retention of a resin-modified glass ionomer adhesive in non-carious cervical lesions. A 6-year follow-up.
OBJECTIVES The purpose of this study was to evaluate the clinical retention of a new resin-modified glass ionomer cement based adhesive combined with a hybrid resin composite or a poly-acid modified resin composite in non-carious cervical lesions during a 6-year period . METHODS The resin-modified glass ionomer adhesive ( Fuji Bond LC ) , was placed in 73 cervical lesions , 36 with a universal hybrid resin composite ( Tetric Ceram ) and 37 with a poly-acid modified resin composite ( Hytac ) . Fifty-one in lesions with sclerotic dentin and 22 in non-sclerotic ones . Of the sclerotic lesions 38 were slightly roughened with a diamond bur before conditioning . The restorations were evaluated with slightly modified USPHS criteria every six months during a 6-year period . RESULTS All except six restorations were evaluated during the 6 years . Twelve ( 17.9 % ) were lost , four Tetric Ceram ( 11.8 % ) and eight Hytac ( 24.2 % ) ( p<0.05 ) . Four were found in non-sclerotic lesions ( 20.0 % ) and eight in sclerotic lesions ( 17.0 % ) . The differences between the sclerotic and non-sclerotic and the roughened and non-roughened lesions were not significant . CONCLUSIONS The resin-modified glass adhesive showed a superior clinical retention combined with the resin composite material , with an annual failure rate of 2 %
