The in vitro uptake of various ions in scaled root surfaces from TiF<sub>4</sub> and acidulated phosphate fluoride (APF) solutions, both with 1.1 M F and pH 1.0, was compared with that from a NaF solution, 0.5 M F, pH 7.1, using electron microprobe analysis, microradiography and polarized light microscopy. The mean F concentration (1.7%) and the mean depth (17 μm) of zones showing F increase following treatment with TiF<sub>4</sub> solution were much greater than in the NaF group. A fine layer of Ti-containing material covered the surface of the specimens. The APF solution caused even greater depositions of F, but a marked subsurface demineralization. Thus, TiF<sub>4</sub> and APF solutions with the same F molarity and pH showed different effect on the root surfaces. The results indicate that the use of TiF<sub>4</sub> in the topical application of fluoride may have several advantages. Further in vitro studies are warranted.
