title: A retrospective look at esthetic resin composite and glass-ionomer Class III restorations: a 2-year clinical evaluation.
abstract: OBJECTIVE
  A restorative material for Class III cavities must, besides being functional, be esthetically satisfactory, providing good working conditions and several shade and color options. A clinical evaluation was initiated to compare the suitability of resin composite and glass-ionomer cement materials for such restorations.
  
  
  METHODS
  Forty-two Class III conservative cavities, esthetically important because of facial extensions, were selected. Resin composite restorations were placed in 21 cavities, and the remaining 21 were restored with glass-ionomer cement. The following characteristics were studied: color or esthetics, anatomic shape, surface texture, staining, marginal infiltration, dental plaque retention, and occurrence of fracture. After 24 months, the restorations were evaluated.
  
  
  RESULTS
  The only statistically significant difference between the resin composite and glass-ionomer cement restorations in the experimental period involved color or esthetics.
  
  
  CONCLUSIONS
  Resin composites and glass-ionomer materials provide excellent functional and esthetic results in Class III cavities when properly indicated.
