title: Long-term clinical performance of esthetic primary molar crowns.
abstract: OBJECTIVE
  The aim of the study was to report the long-term clinical performance of esthetic primary molar crowns and compare them to that of stainless steel crowns (SSC).
  
  
  METHODS
  Twenty crowns (10 conventional and 10 esthetic) placed in 10 children who had participated in a previously reported study, were assessed again after 4 years. The crowns were evaluated clinically and radiographically according to the following parameters: gingival health, marginal extension, crown adequacy, proper occlusion, proximal contact, chipping of the facing (for esthetic crowns only), and cement removal.
  
  
  RESULTS
  At the 4 year evaluation, all the esthetic crowns showed chipping of the facing. No difference was found for marginal extension, occlusion, crown adequacy and periodontal health between SSCs and the esthetic crowns.
  
  
  CONCLUSIONS
  After 4 years, all the esthetic crowns presented chipping of the facing and, consequently, a very poor esthetic appearance.
