Currently, the demand for tooth-colored restorations in children and young adults is increasing. Stainless steel crown (SSC) is the most common restoration for decayed primary molars. Given the dark metallic color of SSC, the esthetic appearance of this restoration is poor and subsequently their acceptance is still a matter of debate.
This study was conducted to evaluate the effect of restoration's color on children's daily living conditions and compare the clinical and radiographic success rates of composite resins with SSC in primary molars.
This clinical trial study was performed on 70 primary molars in 44 healthy 4- to 7-year-old children. The children were randomly divided into two groups restored with SSC and restored with composite resin. Two researcher-made questionnaires were used to assess the children's satisfaction concerning the appearance and color of restoration. The data were analyzed with SPSS 20 using chi-squared, Fisher's, and Mann-Whitney U tests. The significance level was set at p< 0.05.
Children's satisfaction with restoration color in the treatment session was 75% in the SSC group and 85% in the composite resin group. However, the difference was not statistically significant (p= 0.246). After one year of follow-up, the satisfaction rate decreased to 69% in the SSC group and increased to 90.6% in the composite resin group, with a significant difference (p< 0.001). Moreover, the frequency of clinical success was 95% in the SSC group and 96.7% in the composite resin group, with no statistically significant difference (p= 0.749). The frequency of radiographic success was 87.5% in the SSC group and 100% in the composite resin group; this difference was not significant (p= 0.061).
The results verified that restoration color was not important for cooperative children in the treatment session. However, after one year, children who received composite resin restorations were pointedly more satisfied than those who were treated with SSC restorations.
目前，儿童和青少年对牙齿颜色修复体的需求在增加。不锈钢冠（SSC）是治疗乳牙龋齿最常用的修复体。鉴于SSC的深色金属外观，这种修复体的美观性较差，因此其接受度仍存在争议。
本研究旨在评估修复体颜色对儿童日常生活状况的影响，并比较复合树脂与SSC修复乳牙的临床和影像学成功率。
本临床试验研究对44名4至7岁健康儿童的70颗乳牙进行。将儿童随机分为两组，分别用SSC修复和复合树脂修复。使用两份研究者自制的问卷来评估儿童对修复体外观和颜色的满意度。数据采用SPSS 20软件进行分析，使用卡方检验、Fisher检验和Mann-Whitney U检验。显著性水平设定为p<0.05。
治疗期间，SSC组儿童对修复体颜色的满意度为75%，复合树脂组为85%。然而，差异无统计学意义（p = 0.246）。随访一年后，SSC组的满意度降至69%，复合树脂组升至90.6%，差异有统计学意义（p<0.001）。此外，SSC组的临床成功率为95%，复合树脂组为96.7%，差异无统计学意义（p = 0.749）。SSC组的影像学成功率为87.5%，复合树脂组为100%；差异不显著（p = 0.061）。
结果证实，修复体颜色对治疗期间配合的儿童并不重要。然而，一年后，接受复合树脂修复的儿童比接受SSC修复的儿童明显更满意。
