Introduction Advancements in dental materials have enhanced aesthetic treatments for managing dental caries and injuries in primary dentition. Bis-acryl composite-based temporization materials are now preferred for restoring primary crowns due to their superior properties. However, prolonged exposure to dietary and hygienic factors can lead to discoloration and roughness, making efficient polishing essential to prevent plaque buildup. Objective This study aims to evaluate biofilm formation on temporization material polished with different polishing systems. Methods This study tested bis-acryl methacrylate temporization material. Thirty disk-shaped specimens were prepared and divided into three groups according to the polishing system used (n = 10 per group): Shofu Super Snap mini kit (Shofu, San Marcos, CA), aluminum oxide polishing paste, and propol polishing paste. Each group's specimens were polished according to the manufacturer's instructions. Surface roughness (SR), scanning electron microscopy (SEM) morphological analysis, and biofilm formation were assessed for each group. Results The results showed significant differences in roughness average (Ra) values among the polishing materials, with the Shofu Super Snap mini kit having the highest roughness (Ra = 2.04), followed by propol polishing paste (Ra = 1.30) and aluminum oxide paste (Ra = 0.75). Additionally, polishing methods significantly affected mean colony-forming unit (CFU) levels, with the first group having the highest mean CFU value (0.24), with SEM images showing substantial biofilm formation by . Conclusion Bacterial biofilm formation on the aluminum oxide paste group's surface differed from that on the propol polishing paste and aluminum oxide disc groups. The polishing techniques that we tested significantly influenced surface properties and biofilm formation. These findings suggest that selecting an appropriate polishing system can reduce the risk of gingival inflammation associated with temporization materials.
引言 牙科材料的进步提升了乳牙龋齿和损伤治疗的美学效果。基于双丙烯酸酯复合材料的临时修复材料因其优越性能，目前成为修复乳牙冠的首选。然而，长期暴露于饮食和卫生因素会导致材料变色和粗糙，因此高效抛光对于防止牙菌斑积聚至关重要。目的 本研究旨在评估用不同抛光系统抛光的临时修复材料上生物膜的形成情况。方法 本研究测试了甲基丙烯酸双丙烯酸酯临时修复材料。制备了30个圆盘形样本，并根据使用的抛光系统分为三组（每组n = 10）：松风超快速迷你套装（松风，加利福尼亚州圣马科斯）、氧化铝抛光膏和蜂胶抛光膏。每组样本均按照制造商说明进行抛光。对每组样本评估表面粗糙度（SR）、扫描电子显微镜（SEM）形态分析和生物膜形成情况。结果 结果显示，抛光材料之间的平均粗糙度（Ra）值存在显著差异，松风超快速迷你套装的粗糙度最高（Ra = 2.04），其次是蜂胶抛光膏（Ra = 1.30）和氧化铝膏（Ra = 0.75）。此外，抛光方法对平均菌落形成单位（CFU）水平有显著影响，第一组的平均CFU值最高（0.24），SEM图像显示大量生物膜形成。结论 氧化铝膏组表面的细菌生物膜形成与蜂胶抛光膏组和氧化铝盘组不同。我们测试的抛光技术对表面性能和生物膜形成有显著影响。这些发现表明，选择合适的抛光系统可以降低与临时修复材料相关的牙龈炎症风险。
