title: The effectiveness of compomer as a root-end filling: a clinical investigation.
abstract: OBJECTIVE
  This study investigates the treatment outcome of a root-end filling technique that uses a light-cured compomer combined with a light-cured dental adhesive.
  
  
  METHODS
  The study used 34 single-rooted teeth restored with post, core, and crowns. A shallow concave apical preparation was filled with a light-cured compomer with a light-cured dental adhesive. As a control, a chemically cured glass ionomer was used with a conventional root-end preparation. A follow-up clinical and radiographic evaluation of the treatment result was conducted after 1 year.
  
  
  RESULTS
  A significantly higher success rate (P<.015) was observed in the treatment group that used a compomer (89% complete healing) compared to glass ionomer (44% complete healing).
  
  
  CONCLUSIONS
  When used as a retrograde root filling in a shallow concave preparation, a light-cured compomer and a dental adhesive improves healing regardless of the quality of the remaining root filling.
