title: Clinical evaluation of a polyacid-modified resin composite (Dyract) in Class III cavities: 5-year results.
abstract: OBJECTIVE
  This study evaluated the 5-year clinical performance of Dyract polyacid-modified resin composite material in Class III cavities.
  
  
  METHODS
  62 Class III cavities in 30 patients were restored with Dyract. Two experienced, calibrated examiners evaluated the restorations clinically at baseline and at 1-, 2-, 3-, 4-, and 5-year recalls, according to the modified Ryge criteria.
  
  
  RESULTS
  After 5 years, a total of six restorations had failed and the cumulative failure rate was 94.6%. By the 5-year recall, one restoration was replaced due to pulpitis and five were replaced due to secondary caries. After 5 years, marginal discoloration was statistically significant (P= 0.0002).
