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 .
Durability of three simplified adhesive systems in Class V non-carious cervical dentin lesions.
PURPOSE To investigate the durability of three simplified systems in Class V non-carious abrasion/erosion lesions . METHODS 144 non-carious cervical dentin lesions were restored either with Clearfil Liner Bond 2 , a 2-step self-etching primer ( n = 46 ) , One Coat Bond , a one bottle total-etch system applied with one coat ( n = 46 ) , or Prompt-L-Pop , a 1-step self-etching primer ( " all-in-one " ) ( n = 52 ) , in 90 individuals . Ninety-eight of the lesions showed sclerotic dentin and 46 were non-sclerotic . Sixty-one were slightly roughened with a diamond bur before conditioning . The restorations were evaluated every 6 months during a 2-year period with slightly modified USPHS criteria . RESULTS All except three restorations were evaluated over 2 years . The cumulative loss rates for Clearfil Liner Bond 2 , One Coat Bond and Prompt-L-Pop were at 6 months : 4.3 , 2.2 and 3.9 % , at 18 months : 4.3 , 10.9 and 15.4 % and at 24 months : 8.7 , 13.0 and 21.2 % , respectively . The cumulative loss rates of the material s in sclerotic lesions ( 15.7 % ) versus non-sclerotic lesions ( 14.0 % ) were not significanty different . Restorations placed with a diamond bur-roughened lesions showed a loss rate of 14.5 % , while for the non-roughened lesions the frequency was 14.8 %
