The surface free energy γ s of human dentin treated with sodium fluoride, acidulated phosphate fluoride, and aminfluoride solutions has been determined by means of contact angle measurements. Application of an aminfluoride solution slightly increased the total surface free energy from 75 to 80 erg. cm −2 . The γ s values of dentin after a neutral sodium fluoride application decreased to 62 erg. cm −2 . APF solutions hardly influenced the surface free energy γ s . This study showed that fluoride applications change the surface free energy of human dentin. Extrapolation of the results of this study and the in vitro results on cell spreading indicated that aminfluoride applications might be favorable for the reattachment of periodontal tissues.
