Fig. 4From: Remineralization of enamel subsurface lesions using toothpaste containing tricalcium phosphate and fluoride: an in vitro µCT analysisMean mineral density (MD) profiles of all specimens from the experimental groups (line traced from a composite of all seven in each group). The mean MD profiles of the fTCP − F − , fTCP + F − , fTCP − F + , and fTCP + F + groups are shown. Graphs show the mean MD profiles, as determined via mineral volume (%; y-axis) vs. distance (µm; x-axis) at baseline (sound) and before and after 12 days of pH-cyclingBack to article page
