title: A three-year evaluation of restorations placed with a smear-layer-mediated dentin bonding agent in non-carious cervical lesions.
abstract: OBJECTIVE
  To evaluate the handling characteristics, clinical behavior, and effectiveness of Coltene ART Bond/Brilliant restorations in mixed Class V preparations in maxillary premolar and canine teeth of adult patients over a three-year period.
  
  
  METHODS
  Single-center, uncontrolled, clinical evaluation of 50 restorations in 26 patients extending over 36 months.
  
  
  RESULTS
  At three years, 34 restorations, or 68% of those originally placed, in 20 patients were available for review. One of the 34 restorations had been lost 15 months after placement. In terms of marginal integrity and staining, anatomic form, surface texture and staining, and postoperative sensitivity, over 90% of the restorations reviewed at three years were rated alpha. Following difficulties in obtaining excellent color match in relation to 14 (28%) of the restorations at the time of placement, only 44% of the restorations were rated alpha at three years.
  
  
  CONCLUSIONS
  It was concluded that with the possible exception of excellent color match, ART Bond/Brilliant restorations may be found to perform favorably in mixed Class V lesions in selected adult patients over a period of at least three years. The findings indicate that resin composite restorations placed with a smear-layer mediated dentin bonding agent may be found to have a favorable clinical outcome in non-carious cervical lesions.
