Remineralization Potential of Nanohydroxyapatite Toothpaste Compared with Tricalcium Phosphate and Fluoride Toothpaste on Artificial Carious Lesions
Table 3
An analysis of variance (ANOVA) 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), and percentage of hardness recovery (% HR), remineralization potential (RP), and percentage of remineralization potential (% RP).
