title: Three-year clinical evaluation of endodontically treated anterior teeth restored with a polyethylene fibre-reinforced composite.
abstract: BACKGROUND
  Polyethylene fibre-reinforced composites (FRCs) have been under development for some time. However, there is a lack of data on the clinical performance of these restorations. The purpose of this descriptive study was to evaluate the clinical performance of endodontically treated anterior teeth restored using polyethylene FRCs.
  
  
  METHODS
  Eighty-seven endodontically treated anterior teeth in 65 patients were restored with polyethylene FRCs. The restorations were placed by three operators. The patients were recalled for examinations every year for up to three years. The restorations were evaluated using modified Ryge and USPHS criteria.
  
  
  RESULTS
  A statistical analysis showed no significant difference in marginal irregularity, marginal discolouration, surface texture, wear/anatomic form, fracture and retention, radiographic appearance, or debonding between the baseline and three-year results.
  
  
  CONCLUSIONS
  Based on our three-year examination results, polyethylene FRC restorations appear to be clinically successful.
