AI Article Synopsis
- The study assessed the clinical performance of posterior preveneered stainless steel crowns over three years, focusing on factors like fracture rates and aesthetics.
- The statistical analysis of 34 crowns revealed a decline in fracture-free crowns from 81% at one year to 53% after three years, but most fractures had little aesthetic impact.
- Both crown types performed similarly, with a parental satisfaction rating of 8.3 out of 10, highlighting that while veneer loss may occur, it generally doesn't significantly affect overall satisfaction.
Article Abstract
Purpose: The purpose of this study was to evaluate the clinical performance of posterior preveneered stainless steel crowns after three years.
Methods: NuSmile crowns and Kinder Krowns were randomly allocated on paired molars using a split-mouth design. Variables such as fracture, wear, gingival health, and esthetics were recorded. (P<.05).
Results: Statistical analysis was completed on 34 paired crowns in 14 children. After three years, 53 percent of crowns were fracture free compared to 81 percent at one year. There was minimal esthetic impact for most fractures due to the location of the veneer fracture, but five crowns had extensive fracture. No difference was reported in the clinical performance between the two crown types. Fracture was more likely to occur where the adjacent tooth was missing. Parents reported a satisfaction rating of 8.3 out of 10.
Conclusions: Clinical performance of both crown types was similar and successful for three years. Facing fracture occurred in 47 percent of crowns but had minimal impact on the esthetic value or parental satisfaction in the majority of cases. These crowns offer an esthetic alternative to the traditional stainless steel crown, but parents should be alerted to the possibility of veneer loss over time.

Purpose: To evaluate the success of a direct chairside method for repair of esthetic facings in NuSmile® and Kinder Krowns® pediatric crowns.
Methods: A rapid direct chairside technique was developed for repair of fractured facings of preveneered primary molar crowns using the Co-Jet system to pretreat the exposed metal subsurface and composite resin (Herculite XRV). A total of 19 posterior crowns were included in the pilot sample.
