title: Evaluation of the 1-year clinical performance of dentin-bonded ceramic crowns and four case reports.
abstract: OBJECTIVE
  Dentin-bonded crowns are a comparatively recent addition to the dentist's armamentarium. Although 1-year data cannot predict the long-term performance of restorations, it may be useful for new treatment modalities, given that it will describe early, catastrophic failures. In this study, the 1-year performance of 109 dentin-bonded crowns was assessed.
  
  
  METHODS
  The crowns were placed in two locations (Glasgow, Scotland, and Belfast, Northern Ireland) for 27 patients. The principal reasons for crown placement were tooth substance loss, esthetic reasons, and tooth fracture. Minimal preparations were used. Ninety-eight crowns were available for review at 1 year.
  
  
  RESULTS
  Ninety crowns were found to be intact, six had a crack visible on transillumination and two had fractured. No crowns had debonded. No secondary caries was noted. No unsatisfactory scores were recorded for marginal adaptation, adjacent gingival health, or color match.
  
  
  CONCLUSIONS
  The dentin-bonded crowns placed during this study provided good overall performance at 1 year.
