Studies on the techniques of topical application with fluoride gel. 2. Standardization on the amounts of gel applied.

Abstract

In the previous report, the results of an experiment for utilization of the practically available tray in our effort to introduce a new technique for the application of fluoride gel products to patients were described. Through the experiment, it was found that the groove in the sponge tray is too shallow for the application of gel, and the need for standardization of the proper amount of fluoride gel for application was felt. In the present study, an experiment using an improved version of a ready-made sponge tray was conducted. Simultaneously, the standardization of the amount of gel for application using cotton pellets, sponge tray and custom-fitted tray was attempted with good results. However, problems still remain concerning the way of accommodating the standardized amount of gel in a tray, and how to apply the gel intraorally using the cotton pellets.
