The aim of the study was to compare the abrasive effect of miswak and toothbrush filaments on enamel tooth surface.
Ten maxillary central incisors were obtained from Division of Maxillofacial Surgery, King Saud University, College of Dentistry. Twenty specimen were prepared, they were divided into 4 groups (1) Butler toothbrush; (2) Aquafresh toothbrush; (3) Miswak; (4) Control group. Miswak, Aquafresh 311 and Butler 311 tooth brush were used with light pressure in one direction motion for 60 seconds on enamel surface. The specimens were prepared for Scanning Electron Microscopy (SEM) examination. The middle filament from toothbrushes and miswak were also prepared for SEM.
Showed that filaments end-surface texture play a major role in abrasive active activity and enamel tooth surface loss.
The Butler 311 toothbrush and miswak showed lesser effect on enamel as compared to Aquafresh 311 toothbrush.
本研究旨在比较阿拉伯树牙刷丝与普通牙刷刷毛对牙釉质表面的磨损作用。
从沙特国王大学牙科学院颌面外科获取10颗上颌中切牙。制备20个样本，将其分为4组：（1）巴特勒牙刷；（2）佳洁士牙刷；（3）阿拉伯树牙刷；（4）对照组。使用阿拉伯树牙刷、佳洁士311牙刷和巴特勒311牙刷在牙釉质表面以轻压力沿一个方向移动60秒。制备样本用于扫描电子显微镜（SEM）检查。牙刷和阿拉伯树牙刷的中间刷毛也制备用于SEM检查。
表明刷毛末端表面质地在磨损活性和牙釉质表面损失中起主要作用。
与佳洁士311牙刷相比，巴特勒311牙刷和阿拉伯树牙刷对牙釉质的影响较小。
