Nano-Hydroxyapatite Gel and Its Effects on Remineralization of Artificial Carious Lesions
Table 4
Tukey’s post hoc multiple comparisons of hardness at baseline (HB), hardness upon demineralized process (HD), hardness upon an applied remineralizing agent (HA), hardness difference determined between after demineralization and after remineralization (Hdiff = HA − HD), and percentage of surface microhardness recovery (%HR) after applied remineralizing agents (HA) compared to demineralization (HD) for each treatment group.
