Objective: To evaluate in a randomized controlled study the 2-year clinical durability of a one-step universal adhesive bonding system placed with the selective etch technique and a 2-step self-etch adhesive in Class II restorations.
Material and methods: Each of 28 male and 29 female participants (mean age 58.3 yr; range33-89) received at least two, as similar as possible, extended Class II restorations. The cavities in each of the 60 individual pairs of cavities were randomly distributed to the 1-step universal adhesive (All Bond Universal: AU) and the control 2-step self-etch adhesive (Optibond XTR: OX) before the operative procedure started. A low shrinkage resin composite (Aelite LS) was used for all restorations. The restorations were evaluated using slightly modified USPHS criteria at baseline, 1 and 2 years.
Results: No postoperative sensitivity was reported. 116 Class II restorations were evaluated at two years. Five restorations, 2 AU and 3OX, failed during the follow up, which resulted in non-significant different success rates of 96.5% (AU) and 94.8% (OX)(p>0.05). The annual failure rates during the follow up were 1.8% and 2.6%, respectively.The main reason for failure was resin composite fracture.
Conclusion: Class II resin composite restorations placed with a selective etch approach and a one-step universal adhesive showed good short time effectiveness.
Clinical relevance: Posterior restorations placed with the universal adhesive showed highly acceptable clinical performance during the short time evaluation.
