Clinical outcomes for primary anterior teeth treated with preveneered stainless steel crowns.
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.
