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 ) .
3-year clinical evaluation of modified Gluma adhesive systems in cervical abrasion/erosion lesions.
PURPOSE To study the clinical performance of two c and i date s for improvement of the original Gluma bonding system . MATERIAL S AND METHODS Eight teeth with cervical buccal abrasion/erosion lesions were identified in 40 patients . The lesions were conditioned with an oxalic acid solution followed by either a HEMA-glutaraldehyde bonding agent or a formamide-containing bonding agent . The lesions were restored with a hybrid composite . Each patient received the same number of restorations with the two different bonding formulations . All restorations were made by the same operator ( JK ) . Evaluations were based on the USPHS system . RESULTS No difference between the two groups as to retention , marginal adaptation and discoloration was observed after 3 years . Eight restorations were lost and a slight increase in marginal discoloration was seen during the observation period
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 .
