Remineralization patterns and F profiles in remineralized bovine enamel subjected to prior demineralization have been studied using a new acid-abrasion procedure. These data were then compared to those obtained from the perchloric acid-etch procedure employed in our laboratories and the data obtained by the previously reported abrasion (without acid) procedure. All three of the procedures (namely acid-abrasion, abrasion and acid-etch) gave reasonably close F profiles, remineralization patterns and cumulative 45Ca/F ratios in the enamel samples remineralized at a pKFAP of 108. The newly developed acid-abrasion procedure is much more satisfactory than the relatively tedious abrasion (without acid) method, especially when enamel analyzed up to depths as great as 50–100 μm are involved.
