To evaluate the in vitro effects of two commonly used commercial herbal toothpastes (Dabur Meswak and Patanjali Dant Kanti) on the colour stability, surface texture, and microhardness of two commonly used aesthetic restorative materials, i.e., nanofilled composite and resin-modified glass ionomer cement (NFC and RMGIC).
The samples were brushed twice daily using two herbal toothpastes, Dabur Meswak (Dabur India Ltd) and Patanjali Dant Kanti (Patanjali Ayurved Ltd, India) and powered toothbrush. Atomic force microscopy, spectroscopy, and digital micro hardness testing were used to estimate the changes in the surface roughness, colour change, and hardness of the samples, respectively, at baseline and after six months.
Regarding colour change, a statistically significant difference (P < 0.05) was observed between baseline and six months in both the RMGIC and NFC for both herbal toothpastes. Both RMGIC and NFC had higher Ra values when brushed with either toothpaste, indicating a rough surface. The greatest increase in the mean difference in microhardness was observed for the Patanjali Dant Kanti toothpaste samples brushed on both NFC and RMGIC.
In our work, herbal toothpaste increased surface roughness and microhardness and caused colour changes in the two most commonly used aesthetic restorative materials.
Herbal toothpastes affect the surface texture of aesthetic dental restorative materials. Dental professionals may need to educate their patients to be cautious regarding the prolonged use of herbal toothpaste.
评估两种常用的商业草本牙膏（达布尔Meswak和帕坦伽利丹特坎蒂）对两种常用的美学修复材料，即纳米填充复合材料和树脂改性玻璃离子水门汀（NFC和RMGIC）的颜色稳定性、表面质地和显微硬度的体外影响。
使用两种草本牙膏，即达布尔Meswak（印度达布尔有限公司）和帕坦伽利丹特坎蒂（印度帕坦伽利阿育吠陀有限公司）以及电动牙刷，每天对样品刷牙两次。分别在基线期和六个月后，使用原子力显微镜、光谱学和数字显微硬度测试来估计样品的表面粗糙度、颜色变化和硬度变化。
关于颜色变化，两种草本牙膏的RMGIC和NFC在基线期和六个月之间均观察到具有统计学意义的差异（P < 0.05）。用任何一种牙膏刷牙时，RMGIC和NFC的Ra值均较高，表明表面粗糙。在NFC和RMGIC上刷牙的帕坦伽利丹特坎蒂牙膏样品的显微硬度平均差异增加最大。
在我们的研究中，草本牙膏增加了表面粗糙度和显微硬度，并导致两种最常用的美学修复材料出现颜色变化。
草本牙膏会影响美学牙科修复材料的表面质地。牙科专业人员可能需要教育患者谨慎长期使用草本牙膏。
