This study evaluates Vickers microhardness and surface roughness in Biodentine cement (M1) and glass-ionomer cement Fuji IX (M2), both immersed in mouthwash.
Fifty-four samples were randomly distributed in distilled water (S1), Listerine Cool Mint (S2), and Colgate Plax (S3). Each sample was put in a flask with mouthwash for 2 min, under vibration, twice a day for 21 days. Microhardness and surface roughness were assessed at 48 h (T0), 7 days (T1), 14 days (T2), and 21 days (T3).
For roughness: time (T), solution (S) and material (M), TxM, and SxM and for microhardness: M, TxS, TxM, and SxM were statistically significant. T3, M1, M1T3, and M1S1 presented the highest surface roughness. M2, M1T0, M1T1, M1T2, M1S1, and M1S2 presented higher microhardness.
Biodentine showed higher surface roughness for T1, T2, and T3 and higher microhardness for T0, T1, and T2 against Fuji IX. Biodentine presented higher microhardness independently of solution.
本研究评估了生物活性玻璃粘固粉（M1）和玻璃离子水门汀富士IX（M2）在漱口水浸泡后的维氏显微硬度和表面粗糙度。
将54个样本随机分配到蒸馏水（S1）、李斯德林冰薄荷漱口水（S2）和高露洁全效漱口水（S3）中。每个样本置于装有漱口水的烧瓶中，在振动条件下浸泡2分钟，每天两次，共21天。在48小时（T0）、7天（T1）、14天（T2）和21天（T3）时评估显微硬度和表面粗糙度。
对于粗糙度：时间（T）、溶液（S）、材料（M）、TxM、SxM；对于显微硬度：M、TxS、TxM、SxM具有统计学意义。T3、M1、M1T3和M1S1表面粗糙度最高。M2、M1T0、M1T1、M1T2、M1S1和M1S2显微硬度较高。
与富士IX相比，生物活性玻璃粘固粉在T1、T2和T3时表面粗糙度更高，在T0、T1和T2时显微硬度更高。生物活性玻璃粘固粉的显微硬度较高，与溶液无关。
