Abstract :

Aim: This randomized clinical trial (RCT) compared the clinical outcomes of two full-coronal restorations (Stainless steel crowns SSCs and zirconia crowns Nu/ZR) in carious primary molars teeth. Materials & Methods: Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who need restorations will be screened for inclusion criteria till 120 teeth are recruited (60 teeth for SSC restorations and 60 for Nu/ZR restorations). Split mouth technique will be used to ensure equalizing variables for both groups. Randomization will be done using SPSS software version 20.0. A simple descriptive statistic will be used for analysis by wilcoxon signed-rank test. Level of significance will be set at (�± = 0.05) and level of confidence at (95%). Results: While looking at the improvements in gingival health relative to interventions, both zirconia and SSC have significant changes through all time points. However, zirconia performed better at the third month with 80% compared to SSC with only 13.3% improvement with p-value<0.001 and 0.005 respectively. At the sixth month, all samples under group zirconia already improved while only 73.3% from SSC show improvement. The remaining samples happened to have positive changes at the 12th month. Regarding the plaque retention also the zirconia crowns shows improve performance than SSC. Conclusion: As both SSC and zirconia crowns presented to be excellent choice for posterior teeth restorations, however we can conclude that zirconia crowns performed better regarding gingival response to the material of restoration and plaque retention despite its excessive cost.
