简要总结
the study evaluate the clinical outcome of zirconia versus lithium disilicate overlays restorations for restoring vital young permanent first molar teeth affected with moderate form of molar Incisor hypomineralization: randomized clinical trial.
详细描述
To compare the one-year clinical outcome of zirconia versus lithium disilicate overlays restorations. Materials and methods: Twenty patients were distributed into two groups in relation to the material used for the fabrication of overlays restorations; group (Z) (n=10): patients received zirconia restorations, group (EC): patients received IPS E.max Cad restorations. Clinical and radiographic evaluations of these restorations were carried out at base line (1 week), 3, 6 and 12 months after cementation using FDI World Dental Federation criteria

结局指标
主要结局
Restoration Evaluation
时间窗: one year
Restorations were assessed clinically using dental explorer, mirror and radiographically according to FDI World Dental Federation criteria over one-year period at (base line "1 week", 3, 6 and 12 months) afterward cementation. There were three assessment categories (esthetics, function, biological) each with five subcategories. From best to worst, the subcategories were: (1) clinically excellent, (2) clinically good, (3) clinically sufficient, (4) clinically not sufficient but repairable and (5) clinically unacceptable. Assessment with category (5) was rated as a clinical failure. Statistical analysis for baseline and follow-up criteria was performed with Wilcoxon-Test (p\<0.05) (SPSS; IBM,Chicago, IL).
