SPHERILEX® 148 has been designed to have a spherical particle shape, a small particle size, and a narrow particle size distribution. The spherical particle shape is very well suited to reside in spherical dentin tubules. Approximately 40 % of the spherical particles are smaller than dentin tubules, and laboratory studies have shown the product has a higher affinity for occluding bovine dentin tubules compared to traditional, non-spherical precipitated silicas. SPHERILEX® 148 also provides high levels of cleaning at low loading levels and has been shown to have reduced wear on enamel surfaces (REA). It is recommended the product should be used at 2 – 5% loading in conjunction”
