Clinical outcome and parental satisfaction of maxillary anterior teeth treated with NuSmile preveneered crowns and Kinder Krowns

Abstract

Background: Treatment of primary maxillary incisors in early childhood caries is problematic because the teeth are small and a restoration should be retentive and esthetic. Aim: The aim of this study was to evaluate the esthetics and durability of two types of preveneered stainless steel crowns by assessing their parental acceptance and clinical outcome over a period of 24 months. Materials and Methods: Forty maxillary primary incisors which had undergone pulpectomy procedure were randomly divided into two groups of twenty teeth each. A split-mouth design was followed wherein every child received at least one each of the two commercially available preveneered stainless steel crowns, namely, NuSmile crowns and Kinder Krowns. Patients were recalled after 6, 9, 12, and 24 months and the crowns were evaluated for clinical outcome and parental satisfaction. Data obtained were collected and subjected to statistical analysis using Chi-square/Fisher's exact test. Results: Overall clinical outcome did not show a significant difference between the two types of crowns. Parental satisfaction for NuSmile crowns and Kinder Krowns was similar. Conclusions: (1) NuSmile and Kinder Krowns performed well over a period of 24 months. (2) Parental satisfaction for both types of preveneered crowns was very high.
