Effect of Stainless-Steel Crown and Preformed Zirconia Crown on the Periodontal Health of Endodontically Treated Primary Molars Correlating with IL-1ß: An In Vivo Study.

OBJECTIVE: The purpose of this study was to evaluate the effect of different crown materials on the interleukinone beta (IL-1ß) content of the gingival crevicular fluid and to study which crown material causes the highest inflammation on the marginal gingiva on a biochemical basis in pediatric patients. STUDY DESIGN: Twenty patients in the age group of 4-8 years with endodontically treated primary molars indicated for crown placement were selected for the study which was further divided into 3 groups for sample consideration: group 1-stainless steel crown, group 2-preformed zirconia crown, and group 3- control group (primary second molar). All assay procedures were carried out and the results of the collected samples were calculated using the ELISA-AID TM technique. RESULTS: On mean comparison among the groups using ANOVA oneway test, P-value turns out to be highly significant, on mean comparison using Tukey's HSD post-hoc test, The p-value was 0.000 ,0.000 ,0.193 on comparing group 1 with group 2, group 1 with group 3, group 2 with group 3 respectively. CONCLUSION: Preformed zirconia crown can be a relative replacement of SSC in primary molars as it causes comparatively less inflammation and with an advantage of esthetics.
