Performance clínica de dois sistemas adesivos em lesões cervicais não-cariosas: 30 meses de acompanhamento: Clinical evaluation of two adhesive systems in noncarious cervical lesions: 30-month clinical trial. Arq. Odontol. [online]. 2011, vol.47, n.3, pp. 119-126. ISSN 1516-0939.

Aim: The objective of this randomized controlled clinical trial was to evaluate the 30-month clinical performance of two adhesive systems in non-carious Class V lesions. Materials and Methods: Sixty-three non-carious cervical lesions were restored with composite resin Polofil M (Voco), together with the Futurabond NR (Voco) or Solobond M (Voco) adhesive systems. Composite restorations were bonded following two approaches: the application of a Futurabond NR following the self-etch approach (G1) and the application of a Solobond M following the etch-and-rinse approach (G2). The restorations were evaluated after 7 days and after 6, 18, and 30 months of clinical service regarding their retention, marginal discoloration and integrity, post-operative sensitivity, and incidence of secondary caries, using USPHS criteria. The data were submitted to the McNemar and Chisquare tests (α=0.05). Results: After 30 months, 12 restorations were lost, 6 in each group. The alpha score percentage of each group was: retention (G1: 77.8%; G2: 81.2%), marginal discoloration (G1: 66.7%; G2: 80.8%), marginal integrity (G1: 61.9%; G2: 80.8%), post-operative sensitivity (G1: 90.5%; G2: 89.4%), and incidence of secondary caries (G1: 95.2%; G2: 100%). No statistically significant difference could be observed between the groups for any of the evaluated criteria (p>0.05). Conclusion: After 30 months of clinical service, both adhesive systems presented similar clinical performances.
