This study evaluated physicochemical properties of eight commercially available mouthrinses, namely surface tension, in vivo enamel contact angle, viscosity, penetration coefficient, acidity and buffer capacity. The penetration coefficient, determined by the surface tension, contact angle and viscosity, is a measure of the ability of a liquid to penetrate into a capillary space, such as interproximal regions, gingival pockets and pores. The acidity is often determined by a compromise of the requirements for taste, enamel remineralization and stability of the solution. Among the eight mouthrinses evaluated, the physicochemical properties differed greatly, in particular, the penetration coefficient which varied by a factor of 1.8 over the products tested. Surprisingly several of the products tested were found to be extremely acidic.
本研究评估了八种市售漱口水的物理化学性质，即表面张力、体内牙釉质接触角、粘度、渗透系数、酸度和缓冲能力。渗透系数由表面张力、接触角和粘度决定，是衡量液体渗透到毛细空间（如邻面区域、龈袋和孔隙）能力的指标。酸度通常由味道、牙釉质再矿化和溶液稳定性等要求之间的折衷来决定。在所评估的八种漱口中，物理化学性质差异很大，特别是渗透系数，在所测试的产品中变化了1.8倍。令人惊讶的是，发现几种测试产品的酸性极强。
