title: Clinical evaluation of Dyract in primary molars: 1-year results.
abstract: OBJECTIVE
  To evaluate the 1-year clinical performance of Dyract in primary molars.
  
  
  METHODS
  55 children (aged 4-9 years) received 1-3 restorations (n = 91) utilizing Dyract, a new restorative material combining properties of both glass ionomers and composites.
  
  
  RESULTS
  The so-called compomer material showed good handling characteristics and a survival rate of 97% after 1 year. Nevertheless, the material demonstrated an average wear of 190 microns during 1 year, with 67% of the restorations having occlusal wear of less than 200 microns. The combination of a low failure rate and the ease of application makes the compomer material very suitable for application in the primary dentition.
