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 materials 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%.
