Satyam Dutt, Satinderpal Singh, Amandeep Kaur

Background: To evaluate and compare the effectiveness of stainless steel crowns, zirconia and strip crowns. Materials & methods: A total of 30 pediatric subjects within the age group of 5 to 8 years were enrolled. Only those subjects were enrolled which had fully erupted mandibular deciduous molar needing crown. The crowns were divided into 3 groups with 10 in each group. Group A: Stainless steel crowns, Group B: zirconia and Group C: strip crowns. Patients were recalled after 3 months and 6 months to evaluate the gingival health and secondary caries. Data was collected and result was analysed using SPSS software. Results: A total of 40 deciduous crowns were included. Gingival health as measured by bleeding with probing was recorded. At the 6-months follow-up also more teeth in the strip crown group were bleeding. However, at the last follow-up visit at 9 months all the groups showed no bleeding. Secondary caries of zirconia crowns, luxa crowns, resin strip crowns and stainless steel crowns were compared. Statistically significant difference was found between them at 9 months. No secondary caries was seen in zirconia crown, luxa and stainless steel crown at 3-, 6-, and 9-month intervals. Conclusion: Outcome of Zirconia crowns was better. Keywords: zirconia, strip crowns.
