Can MI Paste reverse white spot lesions?
MI Paste provides the minerals (calcium and phosphate) to rebuild subsurface areas of defects in enamel, including white spot lesions from dental caries, white spot lesions associated with orthodontic treatment and fluorosis. In these defects, there are subsurface voids which can be very effectively remineralized by applying MI Paste, and this has been shown using optical and also radiographic tests at the University of Melbourne. For some white spot lesions it may be necessary to first pre-treat the lesion before application of MI Paste. This pre-treatment may involve bleaching, acid etching or microabrasion. Recent research at the Dental School at the University of Melbourne has demonstrated that pre-bleaching is an effective pre-treatment for MI Paste application. In order to avoid the incidence of white spots, it is recommended to apply MI Paste twice daily for the entire period that brackets are in place. Immediately after the brackets are removed apply MI Paste twice daily for on
