Abstract

Background: The aim of the study was to evaluate the remineralizing potential of prepared solutions of eggshell powder (ESP) and nano-hydroxyapatite (nHA) on the surface roughness and microhardness of bleached enamel.

Materials and methods: Fifty bovine anterior teeth were selected and cleaned then bleached using a chemically activated in-office bleaching agent then the teeth were randomly allocated into five groups (n = 10) according to the tested remineralizing agents (10% ESP solution, 10% nHA solution, and MI Paste Plus) into; control, bleached, bleached + ESP solution, bleached + nHA solution, and bleached + MI Paste Plus groups. Then, the teeth were tested for surface roughness and microhardness of the bleached enamel, respectively.

Results: There was a statistically significant difference in the surface roughness and microhardness values of the tested groups. The highest surface roughness mean value was found in bleached enamel group, while the least mean value was found in the control group. The highest mean microhardness value was found in the bleached enamel + ESP solution group, while the least mean value was found in the bleached enamel group.

Conclusions: The application of the tested remineralizing agents following the bleaching procedure had improved the surface roughness and microhardness of the bleached enamel. ESP and nHA present promising and potent remineralizing agents.

蛋壳粉和纳米羟基磷灰石对漂白搪瓷表面粗糙度和显微硬度的影响。

背景：本研究的目的是评估蛋壳粉（ESP）和纳米羟基磷灰石（nHA）溶液对漂白搪瓷表面粗糙度和显微硬度的再矿化潜力。材料和方法：选择50颗牛前牙，使用化学活化的办公室漂白剂进行清洁和漂白，然后根据测试的再矿化剂（10%ESP溶液、10%nHA溶液和MI Paste Plus）将牙齿随机分为5组（n=10）；对照、漂白、漂白+ESP溶液、漂白+nHA溶液和漂白+MI Paste Plus组。然后，分别对牙齿表面粗糙度和漂白牙釉质的显微硬度进行测试。结果：试验组的表面粗糙度和显微硬度值差异有统计学意义。漂白搪瓷组的表面粗糙度平均值最高，而对照组的平均值最低。漂白搪瓷+ESP溶液组的平均显微硬度值最高，而漂白搪瓷组的平均硬度值最低。结论：在漂白过程中使用所测试的再矿化剂可以改善漂白搪瓷的表面粗糙度和显微硬度。ESP和nHA提供了有前景和有效的再矿化剂。
