Objectives: The aim of the study was to assess a one-step self-etch adhesive (Futurabond M, 1-SE) and a two-step etch-and-rinse adhesive (Solobond M, 2-ER) used in combination with the nano-hybrid composite (Amaris) in a prospective clinical study on non-carious cervical lesions.
Methods: 110 restorations were placed in 40 patients and graded over 36 months according to aesthetical, functional and biological criteria (Clinical Oral Investigations 2007; 11:5). The four-step etch-and-rinse adhesive Syntac classic (4-ER) combined with the nano-hybrid composite Tetric EvoCeram was used as a control. Cumulative failure rates (CFR), retention rates and Kaplan-Meier survival curves were calculated for each observation period.
Results: After 3 years, the CFR of 33.3% in the 2-ER group was significantly higher compared to those of the 1-SE group (9.1%, p = 0.019) and of the 4-ER group (8.3%, p = 0.035). Additionally, retention rates in the 1-SE and the 4-ER groups were higher compared to 2-ER (p = 0.012 each) after 36 months. Annual failure rates ranged between 2.8% for 4-ER, 3.0% for 1-SE and 11.1% for 2-ER. During the study, restorations in all groups showed progressive marginal deterioration within the limits of clinical acceptance. After 3 years, restorations in the 2-ER and the 4-ER group showed more small defects at dentin than at enamel margins.
Conclusions: The 1-SE group was clinically as successful as the 4-ER, with both performing better than the 2-ER group. Futurabond M/Amaris can be recommended for the restoration of sclerotic non-carious cervical lesions.
