Abstract

This clinical study was directed to evaluate the clinical and radiographic success of Stainless-steel crowns versus zirconia crowns on primary molars. subjects and methods: A total of ten children with twenty pulpotomized primary mandibular molars were involved and categorized into 2 groups; Group I; pulpotomized primary molar teeth restored with zirconia crowns and Group II; pulpotomized primary molar teeth restored with Stainless-steel crowns. The clinical and radiographic evaluations were conducted at baseline, 1-, 3-, and 6-months intervals utilizing the Scoring system. Results: The results of this study showed that was no statistically significant difference between proximal contact areas, marginal adaptations, and restoration failure scores in the two groups at baseline, 1, 3, and 6 months. Stainless Steel crown group showed statistically significantly higher mean OHI scores than the Zirconia crown group at 1 and 6 months. Stainless Steel crown group showed statistically significantly higher mean GI scores than the Zirconia crown group at 3 and 6 months. After 6 months, 70% of the Stainless-Steel crowns showed acceptable clinical and radiographic criteria compared to 100% of the Zirconia crowns. CONCLUSIONS: Zirconia crowns demonstrated better gingival health than the stainless- steel crowns group. Zirconia crowns can be used as a safe esthetic alternative for stainless steel crowns with successful clinical outcomes.
