Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mineral Density	The percent mineral profile of each enamel/dentinel slab's demineralized control and remineralized/treated lesion, obtained from the microdensitometry analysis, will be compared with the median sound enamel percent mineral profile of the same section. A negative value indicates mineral has been lost and, therefore, the lesion has progressed, whereas a positive value indicates mineral has been gained and, therefore, the lesion has regressed.	14 days
Primary	Scanning Electron Microscopy (SEM)	SEM imaging and SEM-EDS analysis will be conducted on TMR sections and whole sections of dentine lesions treated in situ to assess the occlusion of dentine tubules and distribution of elements within the lesions following the experiment.	14 days
