This study aimed to evaluate the effect of surface glazing and polishing of yttrium-stabilized tetragonal zirconia polycrystal ceramic on early dental biofilm formation, as well as the effect of brushing on the removal of adhered bacteria. Two subjects used oral appliances with polished and glazed samples fixed to the right and left sides. After 20 minutes, 1 hour, and 6 hours, the subjects manually brushed the samples on the right side. The samples were analyzed using scanning electron microscopy. Granular material was verified on the samples, especially on irregular surfaces. After 1 hour, there was no significant difference between glazed and polished surfaces in terms of bacterial presence. However, glazed surfaces tended to accumulate more biofilm, and brushing did not completely remove the biofilm. Polished surfaces seem to present a lower tendency for biofilm formation.
本研究旨在评估钇稳定四方多晶氧化锆陶瓷表面上釉和抛光对早期牙菌斑形成的影响，以及刷牙对去除附着细菌的效果。两名受试者使用口腔器具，将抛光和上釉的样本分别固定在左右两侧。20分钟、1小时和6小时后，受试者手动刷右侧的样本。使用扫描电子显微镜对样本进行分析。在样本上，尤其是不规则表面上，发现了颗粒状物质。1小时后，在上釉和抛光表面的细菌存在方面没有显著差异。然而，上釉表面往往会积累更多的生物膜，并且刷牙并没有完全去除生物膜。抛光表面似乎呈现出较低的生物膜形成倾向。
