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 ) .
Three-year clinical evaluation of One-Step in non-carious cervical lesions.
PURPOSE To clinical ly evaluate the 3-year performance of a one-bottle dentin adhesive in the restoration of non-carious cervical lesions ( NCCLs ) with resin composite . MATERIAL S AND METHODS 105 NCCLs were restored with either AElite Flow , Bisco Glaze ( both flowable resin-based composites ) or Silux ( a microfilled resin-based composite ) , using One-Step dentin adhesive . The cavities were cleaned with pumice and water slurry , the dentin lightly roughened with a fine diamond bur , and the restorations placed according to the manufacturer 's instructions . Patients were recalled at 6 months , 1 year , 2 years and 3 years , and restoration integrity and marginal discoloration assessed . RESULTS The overall retention rates were : 6 months , 100 % ; 1 year , 95 % ; 2 years , 87 % ; 3 years , 75 % . Marginal discoloration was negligible , and there was no significant difference among the material s , although there was a trend for it to be greater around the Bisco Glaze 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 .
