Remineralisation of demineralised enamel subsurface lesions can be enhanced by pretreatment of the lesions with base (NaOH). The aim of this study was to test the effect of intralesion pH modulation on remineralisation of demineralised enamel subsurface lesions by casein phosphopeptide-stabilised amorphous calcium fluoride phosphate (CPP-ACFP) in vitro. Two remineralisation models were utilised, the first involving 60-min cyclic pH modulation for 105 h and the second involved short-term cyclic pH modulation (12-min cycle, 240 min total duration) compared with the equivalent time of continuous treatment (200 min total duration). The intralesion pH modulation was achieved by cyclic exposure to..View full abstract
