title: Clinical performance of a self-etch adhesive in Class V restorations made with and without acid etching.
abstract: OBJECTIVE
  To evaluate the clinical performance of a self-etching adhesive in Class V carious lesions with and without acid etching procedures.
  
  
  METHODS
  A total of 183 Class V carious cavities with incisal margins in enamel and gingival margins in cementum were selected and restored with Futurabond NR self-etch adhesive and resin composite Grandio. Restorations were made using three different techniques; after etching of the enamel, after etching the whole cavity for 20s and without acid etching (control). The restorations were evaluated at baseline, 1 and 2 years using USPHS criteria.
  
  
  RESULTS
  No loss of restorations was recorded after 1 and 2 years for all the three restorative techniques. There was no significant difference between the baseline and 2-year results for any of the tested technique. However, restorations made after acid etching showed less marginal discoloration at the enamel margins.
  
  
  CONCLUSIONS
  The clinical performance of Futurabond NR self-etch adhesive was excellent after 2 years. Acid etching of the enamel margin or the whole cavity did not improve the overall quality of the restorations, but displayed less marginal discoloration.
