A scanning electron microscope (SEM) Study was conducted to evaluate the micromorphology of glazed and polished ceramic restoration surfaces after treatment with different types of fluorides with different concentrations and acidity. This study showed that glazed ceramic surfaces appeared to be smoother and more resistant to fluoride agents than polished ceramic surfaces. Fluoride agents with a lower pH (more acidic) and higher in fluoride concentration caused more surface damage to porcelain. Therefore, it is recommended to use a neutral fluoride agent with low fluoride concentration. If the ceramic restoration is to be polished after glazing due to clinical adjustment, it is advisable to reglaze it particularly before fluoride application.
进行了一项扫描电子显微镜（SEM）研究，以评估不同浓度和酸度的不同类型氟化物处理后，上釉和抛光陶瓷修复体表面的微观形态。该研究表明，上釉陶瓷表面似乎比抛光陶瓷表面更光滑，并且对氟化物制剂更具抗性。较低pH值（酸性更强）且氟化物浓度较高的氟化物制剂对瓷器造成的表面损伤更大。因此，建议使用低氟浓度的中性氟化物制剂。如果由于临床调整需要在釉面后对陶瓷修复体进行抛光，建议特别是在应用氟化物之前重新上釉。
