Abstract　： [ABSTRACT] The characteristics of dentin subsurface lesions adjacent to the fluoride-releasing materials was evaluated in vitro. The silgle-sections placed adjacent to the fluoride-releasing materials were demineralized by 0.1 M lactic acid for seven days at 37℃ in gel system and transversal micro-radiography (TMR) analysis was performed. The specimens were received further acid attack with 0.1 M acetic acid for three days and second TMR analysis was made. Significantly increased mineral loss value i.e. △Zl of the non-fluoride-releasing material was obtained in comparison with the fluoride-releasing materials (p<0.05). Moreover it was suggested that if the mineral volume at the surface or the body of the first lesions were low, the △Zl trended to be high, and in proportion to the integrated mineral loss values (△Z) of the first lesion. The fluoride-releasing materials make the surrounding dentin lesion to resist further demineralization.
