title: Clinical outcomes for primary anterior teeth treated with preveneered stainless steel crowns.
abstract: OBJECTIVE
  The purpose of this retrospective study was to explore clinical outcomes for NuSmile anterior preveneered stainless steel crowns.
  
  
  METHODS
  A convenience sample of healthy children treated with anterior crowns was selected from a teaching clinic and private office. Crowns were placed by either a private practice dentist or pediatric dental resident. Clearly defined clinical outcomes were assessed by 3 calibrated examiners at recall, including: (1) presence; (2) chipping; (3) wear; (4) crazing; and (5) marginal location by clinical and radiographic examination. Factors affecting placement--such as operator experience and behavior--were also assessed.
  
  
  RESULTS
  In 46 subjects (21 females, 25 males; mean age at placement=4 years, 2 months), 226 crowns with a mean post-placement time of 12.9 months were evaluated. Only 2 crowns matched natural teeth, with NuSmile crowns lighter in 83% of subjects. Most crowns (86%) were normal in size. Eighty-eight percent resisted fracture for 6 months. All but 3 crowns resisted color change for 6 months. Canine crowns were the least successful, but overall 91% of crowns retained good to excellent clinical appearance.
  
  
  CONCLUSIONS
  NuSmile anterior preveneered crowns are a clinically successful restoration for primary incisors with early childhood caries.
