Tooth brushing is essential for the maintenance of oral health and in particular the prevention of Caries. The brushing process is a complex tribological contact which is influenced by a number of interrelated variables combining to cause the abrasion which results in the cleaning of the tooth surface. This process sits at a precipice where abrasion is required for cleaning but also has the potential to abrade and irreversibly damage the enamel surface. The ultimate goal in tooth paste development is a paste capable of high levels of stain removal with no enamel abrasion. Recent work has indicated that micronized spherical silica has the potential to reduce enamel and dentine abrasion while providing an enhanced level of cleaning, compared to standard angular silica.

刷牙对保持口腔健康，特别是预防龋齿至关重要。刷牙过程是一个复杂的摩擦学接触，它受到许多相互关联的变量的影响，这些变量结合在一起导致磨损，从而清洁牙齿表面。这一过程处于一个悬崖上，需要磨损来清洁，但也有可能磨损和不可逆地损坏釉质表面。牙膏开发的最终目标是一种能够高水平去除污渍而不磨损釉质的牙膏。最近的研究表明，与标准角形二氧化硅相比，微粉化球形二氧化硅具有减少牙釉质和牙本质磨损的潜力，同时提供更高水平的清洁。
