Abstract

Aim: To compare the clinical success rate of Prefabricated Zirconia crowns and stainless steel crowns on primary molars
Materials and methods : It is an in-vivo study which was performed on 52 pulpally treated primary molars of children aged 4–9 years were randomly divided into two equal groups of stainless steel crown and Prefabricated Zirconia crowns. Tooth preparation was done according to the manufacturer’s recommendations and crowns were cemented. All crowns were cemented with Type I Glass ionomer cement (GIC) luting cement. Crowns were evaluated clinically for its crown retention, marginal integrity and gingival health at 3 months and 6 months.
Results : Clinical success for stainless steel crowns and Prefabricated Zirconia crowns towards crown retention and marginal integrity were similar with no statistical difference between them. All Prefabricated Zirconia crowns showed healthy gingiva whereas 53.8% (14 out of 26) Stainless Steel crowns showed mild gingival inflammation at 3 and 6 months which was statistically significant (P ?0.01).
Conclusion: Both prefabricated zirconia and stainless steel crowns showed no statistical difference for crown retention and marginal integrity throughout the study. Gingival health was significantly higher for Prefabricated Zirconia crowns compared with stainless steel crowns. Therefore clinical success rate for Prefabricated Zirconia crowns were better when compared to stainless steel crowns. So Prefabricated Zirconia crowns can be considered as an esthetic alternative in future.
