Fluoride toothpastes containing micrometric or nano-sized sodium trimetaphosphate reduce enamel erosion <i>in vitro</i>

Abstract

The addition of 3% TMPnano to 1100 ppm F toothpastes significantly increases the protective effect against enamel erosion in vitro when compared with its counterparts with micrometric TMP or without TMP. This effect was not influenced by the presence of acquired enamel pellicle and saliva.
