In vitro assessments of white-spot lesions treated with NaF plus tricalcium phosphate (TCP) toothpastes using microtomography (micro-CT)
X-ray microtomography (micro-CT) was used to assess the densities of white-spot lesions (WSL) treated with either a fluoride-free paste, or 0.21 or 1.1% NaF toothpastes containing functionalized tricalcium phosphate (TCP).
