Title:	Clinical Outcomes for Primary Anterior Teeth Treated with Preveneered Stainless Steel Crowns
Abstract:	Purpose: 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. (Pediatr.
