BACKGROUND
Assessing microbial biofilm adhesion to the restorative material's surface is a key factor in determining its success. This study aimed to compare the adhesion of () on stainless steel crowns (SSCs) versus zirconia crowns (ZCs) used for primary molars.
STUDY DESIGN
This in vitro study involved 20 full-coverage crowns, with 10 SSCs and 10 ZCs. A fungal adhesion assay was performed to evaluate adhesion, using colony-forming units (CFU) and cell proliferation assays.
STATISTICS
The Wilcoxon-Mann-Whitney test was applied to compare the groups, with statistical significance set at 5 %.
RESULTS
The study revealed that SSCs had a lower mean CFU value (28.28 ± 4.557 CFU/ml) and cell proliferation rate (49.74 ± 0.4367) compared to the ZC group (30.70 ± 11.0760 CFU/ml and 74.53 ± 0.7014, respectively). However, these differences were not statistically significant.
CONCLUSION
The findings suggest that the selection of crowns for restoring primary molars may not be influenced by adhesion.
背景
评估微生物生物膜对修复材料表面的粘附是决定其成功的关键因素。本研究旨在比较（）在用于乳牙的不锈钢冠（SSC）和氧化锆冠（ZC）上的粘附情况。
研究设计
这项体外研究涉及20个全冠，其中10个SSC和10个ZC。采用菌落形成单位（CFU）和细胞增殖试验进行真菌粘附试验，以评估（）的粘附情况。
统计学方法
采用Wilcoxon-Mann-Whitney检验比较各组，设定统计学显著性水平为5%。
结果
研究表明，与ZC组（分别为30.70±11.0760 CFU/ml和74.53±0.7014）相比，SSC组的平均CFU值（28.28±4.557 CFU/ml）和细胞增殖率（49.74±0.4367）较低。然而，这些差异无统计学意义。
结论
研究结果表明，用于修复乳牙的牙冠选择可能不受（）粘附的影响。
