There is not enough evidence to support one adhesive or bonding strategy over another for treatment of NCCLs .
CLINICAL SIGNIFICANCE Studies with low overall risk of bias demonstrated good clinical performance for adhesives with all four bonding strategies .
However , included studies showed wide variation between adhesives of the same category
OBJECTIVES To establish whether simplified adhesives ( self-etch ) are as clinical ly effective as conventional adhesives ( etch- and -rinse ) with multiple application steps for treatment of non-carious cervical lesions ( NCCLs ) .
NULL HYPOTHESIS there is no difference in the clinical effectiveness of the four different bonding strategies : Three-step etch- and -rinse ; Two-step etch- and -rinse ; Two-step self-etch ; One-step self-etch for treatment of NCCLs .
Clinical evaluation of tooth-colored materials in cervical lesions.
PURPOSE To determine the 18-month clinical performance of four tooth-colored restoratives in non-carious cervical lesions . MATERIAL S AND METHODS Buccal abrasion lesions in 83 teeth were restored with each of the following material s : Fuji Cap II , Fuji II LC , APH/Universal Bond 3 , Lite Fil II A/Imperva Bond . Baseline and an 18-month recall was carried out using the Ryge ( USPHS ) method for retention , color match , marginal adaptation , cavosurface marginal discoloration , anatomic form and secondary caries . RESULTS The USPHS results ( % alfa ) for the four products were , respectively : color match ( 9 % , 48 % , 57 % , 55 % ) , marginal discoloration ( 71 % , 76 % , 52 % , 50 % ) , marginal adaptation ( 24 % , 24 % , 33 % , 15 % ) , anatomic form ( 67 % , 86 % , 95 % , 45 % ) and retention ( 100 % , 95 % , 100 % , 65 % ) . Results indicated that ( 1 ) Fuji Cap II exhibited a poor color match at baseline ( 2 ) Color matching of Fuji II LC was comparable to the resin composites and ( 3 ) seven Lite Fil II/Imperva Bond restorations ( 35 % ) were dislodged after 1 1/2 years
