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 ) .
Five-year clinical evaluation of One-Up Bond F in non-carious cervical lesions.
PURPOSE To evaluate the retention and marginal staining of restorations placed in non-carious cervical lesions using the all-in-one self-etching system , One-Up Bond F and Palfique Estelite resin composite . METHODS Fifty-one non-undercut non-carious cervical lesions received restorations with One-Up Bond F and Palfique Estelite in 15 subjects ( mean age 57.7 years ) by one operator . Teeth were cleaned with pumice and water , restored following the manufacturer 's instructions and evaluated at 6 months , 1 , 2 , 4 and 5 years for retention and presence of marginal staining . RESULTS At 1 year , 42 restorations were evaluated , and all were intact with three restorations showing slight marginal staining . At 2 years , 37 restorations were evaluated from 11 subjects , and all were intact . Marginal staining was observed around nine restorations . At 4 years , 27 restorations and at 5 years , 24 restorations could be evaluated . Marginal staining showed a significant increase at the enamel and cervical margins over the 5 years of the study , with two restorations showing severe , nine mild and 13 no staining . Although a number of restorations could not be evaluated , the retention rate of 92 % at 5 years showed One-Up Bond F/Palfique Estelite resin composite for the restoration of non-carious cervical lesions produced an excellent outcome . Marginal staining was limited to a small number of subjects and is unlikely to be a problem if margins are refurbished at recall visits
