The present study was carried out to assess whether the remineralization of artificial caries like lesion by artificial saliva can be improved by daily 5 minute treatment in a specially formulated remineralizing solution containing Ca, P, Zn, Sr, F. Extracted human premolars were dipped for 24 hours in artificial saliva and subsequently daily for 5 minutes in the remineralizing solution for 3 weeks. Lesions were assessed using transverse microradiography, electron probe microanalysis (EPMA) and scanning electron microscope (SEM). The results showed that remineralization by specially formulated solutions repair the enamel lesion and enhances the salivary remineralizing potential.
