The purpose of this study was to evaluate the effect of different crown materials on the interleukinone beta (IL-1β) 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.
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.
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.
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.
本研究旨在评估不同牙冠材料对龈沟液中白细胞介素-1β（IL-1β）含量的影响，并从生化角度研究哪种牙冠材料会在儿童患者的边缘牙龈引起最高的炎症。
选择了 20 名年龄在 4-8 岁之间、有牙髓治疗的乳磨牙需要戴牙冠的患者参与本研究，该研究进一步分为 3 组进行样本考虑：组 1-不锈钢冠、组 2-预制氧化锆冠、组 3-对照组（第二乳磨牙）。所有检测程序均已完成，并使用 ELISA-AID TM 技术计算收集样本的结果。
使用单因素方差分析（ANOVA oneway test）对组间进行均值比较，P 值为高度显著；使用 Tukey's HSD 事后检验（post-hoc test）对组间进行均值比较，组 1 与组 2、组 1 与组 3、组 2 与组 3 之间的 P 值分别为 0.000、0.000 和 0.193。
预制氧化锆冠可以作为 SSC 在乳磨牙中的替代材料，因为它引起的炎症相对较少，并且具有美观的优势。
