Abstract　： [Abstract] In Japan, topical fluoride application with a fluoride solution has been established as professional dental care. The numbers of children who have experienced it are more and more increasing. As one of tray sets, which was commonly used, has not been imported, we are forced to choose the paint-on technique or application with other types of tray. These techniques are, however, inadequate for some reasons. Besides fluoride gel will be widely used in the near future because it has far more merits compared with fluoride solutions. Therefore, it is necessary to confirm the safety of the application with fluoride gel by measuring the amounts of fluoride remaining in children's mouth. Some children, who were attending the department of preventive dentistry in the hospital attached to Kanagawa Dental College regularly, received the topical fluoride gel application using the paint-on technique with cotton pellets and one tray technique with an improved sponge tray. The subjects' teeth were dried with compressed air, and the fluoride gel was applied topically for two minutes. The amounts of fluoride applied and/or recovered from the mouth were measured, and those retained in the mouth were estimated for each technique. Furthermore, the amounts of excessive gel that were wiped off with gauze and expectorated one minute after application were also evaluated, and these efforts were effective in reducing the amounts of intraoral fluoride residue. The net amounts of fluoride that were retained in the mouth through each technique were very small (0.81, 0.9, 1.1 and 1.6mg, respectively). It was found that the application techniques in the present study had no risks of causing any deleterious effects by applying excessively large amounts of fluoride. In addition, it was shown that some efforts to reduce the intraoral residual fluoride, i.e. the wiping-off of excessive gel with gauze and/or giving the children instructions to expectorate a few times immediately after the treatment were effective.
