Remineralization Potential of Nanohydroxyapatite Toothpaste Compared with Tricalcium Phosphate and Fluoride Toothpaste on Artificial Carious Lesions

Table 4

Post hoc Tukey’s multiple comparisons of baseline hardness (HB), hardness after artificial formation of demineralization (HD), hardness after application of pH-cycling and remineralization process (HR), hardness difference determined between after application of pH-cycling and remineralization process and after artificial formation demineralization (Hdiff = HR − HD), percentage of hardness recovery (% HR), remineralization potential (RP), percentage of remineralization potential (% RP) among no treatment (NT), nanohydroxyapatite toothpaste (NHT), tricalcium phosphate toothpaste (TCPT), and fluoride toothpaste (FT) group.
