Micro-CT analysis of naturally arrested brown spot enamel lesions

This study demonstrated that the mineralization parameters such as density and the thickness of the surface layer as well as distribution patterns through natural enamel brown spot lesions (BSLs) are different from enamel white-spot lesions (WSLs). The higher mineral density of the body of the lesion and the increased thickness of the surface layer in brown spot enamel lesions may suggest possible subsurface remineralization in the majority of naturally arrested BSLs.
