Toothpaste abrasivity should be sufficiently high to give effective cleaning without causing mechanical damage to tooth tissue. A clinical trial carried out to measure the cleaning power of calcium carbonate toothpastes of different abrasivity is described; cleaning power is then related to in vitro dentine abrasivity measurements. These findings are used to derive an expression specifying the toothpaste cleaning power which ensures that a chosen low and cosmetically acceptable level of stain is not exceeded providing a consistent daily brushing routine is adhered to.
牙膏的磨损性应足够高，以实现有效清洁，同时又不会对牙齿组织造成机械损伤。本文描述了一项用于测量不同磨损性碳酸钙牙膏清洁能力的临床试验；随后将清洁能力与体外牙本质磨损性测量结果相关联。这些研究结果被用于推导一个指定牙膏清洁能力的表达式，该表达式确保在坚持一致的每日刷牙习惯的情况下，不会超过选定的低且美观上可接受的污渍水平。
