Abstract

Objective: To clinically evaluate and compare the performance of posterior pediatric zirconia crowns with stainless steel crowns.

Materials and methods: Twenty nine children [3-9 years] were selected and given 70 preformed crowns [35: preformed zirconia crowns, Kinderkrown; 35: stainless steel crowns, KIDZ CROWN]. Crowns were evaluated for retention, marginal integrity, opposing tooth wear, plaque accumulation, gingival inflammation, and proximal contact at 3, 6, 9, and 12th month.

Results: At the end of follow-up period overall success rate with zirconia crown was 93.5% and that of stainless steel crown was 96.7%. Statistical analysis showed no difference between the groups.

Conclusion: Posterior preformed zirconia and stainless steel crowns showed good clinical performance. Preformed zirconia crowns can be an option for posterior full coronal restoration when esthetics is of prime concern for the parent and child.
