The aim of this study was to document changes in plaque pH when an acidic challenge was followed by rinsing with miswak extract (Salvadora persica), and to evaluate the effect of miswak rinse on parotid gland secretion rate. Plaque pH was measured in 3-day-old plaque using the microtouch electrode. Rinsing with miswak extract, compared with water rinsing, resulted in protracted elevation of plaque pH (>6.0). The difference in plaque pH between miswak extract and water rinse was statistically significant at 30 min (p < 0.001). Rinsing with miswak extract stimulated parotid gland secretion (p < 0.01). In conclusion, miswak extract raised the plaque pH, suggesting a potential role in caries prevention.
本研究的目的是记录在酸性刺激后用阿拉伯树胶提取物（佩里树）冲洗时菌斑pH值的变化，并评估阿拉伯树胶冲洗对腮腺分泌率的影响。使用微接触电极测量3日龄菌斑中的菌斑pH值。与用水冲洗相比，用阿拉伯树胶提取物冲洗可使菌斑pH值持续升高（>6.0）。在30分钟时，阿拉伯树胶提取物与水冲洗之间的菌斑pH值差异具有统计学意义（p<0.001）。用阿拉伯树胶提取物冲洗刺激了腮腺分泌（p<0.01）。总之，阿拉伯树胶提取物提高了菌斑pH值，提示其在预防龋齿方面具有潜在作用。
