Clinical success and parental satisfaction with anterior preveneered primary stainless steel crowns

Abstract

Purpose: The purpose of this study was to evaluate the clinical success of and parental satisfaction with treatment using prefabricated resin-faced stainless steel crowns (SSCs; Kinder Krowns, Mayclin Dental Studios, Minneapolis, Minn) on anterior primary teeth.

Methods: Patients treated with Kinder Krowns within the last 3 years were recalled for dinical evaluation and completion of a parental satisfaction survey in this retrospective cross-sectional study. Clinical evaluation was performed for crown retention, facing retention, and resin veneer wear.

Results: Forty-six teeth were evaluated in 12 children. The average age of the crown at the time of examination was 17.5 months (range 5-38 months). All crowns were present in the mouth, and resin fracture resulting in partial or total facing loss was seen in 24% of the crowns. No resin facing fracture or visible wear was seen in 61% of the crowns. Six crowns had total facing loss from fracture (13%), while 5 (11%) had partial facing fracture. Wear (7 crowns, 15%) was limited to less than the incisal one third of the crown. The parental satisfaction with the preveneered SSCs overall was high, with satisfaction for appearance and the shape being the lowest.

Conclusions: Kinder Krown prefabricated resin-faced SSCs showed a low failure rate, and the parental satisfaction with treatment was positive.
