The popularity and availability of chewing sticks (Salvadora persica) in the Asia, Middle East and Africa make them a commonly used oral hygiene tool in those societies. Salvador persica chewing stick called miswak is frequently used in Saudi Arabia. The antimicrobial effects of miswak has been well documented. The aim of this study is to find our the effect of aqueous extracts of miswak on healthy and periodontally involved human dentine with Scanning Electron Microscopy (SEM) in vitro. 25% aqueous extract of freshly prepared miswak solution was used for the study. Twelve human premolars teeth (6 healthy and 6 with periodontal disease) recently extracted for orthodontic and periodontal reasons were used. 24 SEM specimens were prepared and treated with miswak extract with different conditions e.g. soaking and burnishing with miswak extract. Soaking the healthy and periodontally diseased root dentine in miswak extract resulted in partial removal of smear layer and occlusion of dentinal tubules was observed in dentine specimens burnished with miswak solution. Further research is needed to evaluate the effect of aqueous extract of miswak on etched human dentine at higher concentrations.
咀嚼棒（佩里扁桃）在亚洲、中东和非洲很常见且容易获取，这使它们成为这些地区常用的口腔卫生工具。在沙特阿拉伯，被称为“米斯瓦克”的佩里扁桃咀嚼棒经常被使用。米斯瓦克的抗菌作用已有充分记录。本研究的目的是通过体外扫描电子显微镜（SEM）来探究米斯瓦克水提取物对健康和患有牙周疾病的人类牙本质的影响。本研究使用了新鲜制备的米斯瓦克溶液25%的水提取物。使用了最近因正畸和牙周原因拔除的12颗人类前磨牙（6颗健康的和6颗患有牙周疾病的）。制备了24个SEM标本，并在不同条件下用米斯瓦克提取物处理，例如用米斯瓦克提取物浸泡和打磨。将健康和患有牙周疾病的牙根牙本质浸泡在米斯瓦克提取物中会导致部分玷污层去除，在用米斯瓦克溶液打磨的牙本质标本中观察到牙本质小管堵塞。需要进一步研究以评估更高浓度的米斯瓦克水提取物对酸蚀人类牙本质的影响。
