[The use of iontophoresis in dental practice].

The effect of hypersensitivity reducing local NaF-gel treatment with or without iontophoresis was evaluated. Air test was used for pain and pain reduction evaluation. Three consecutive treatments (0, 2, 5 weeks) and a 3 month control examination was performed on 20 and 16 patients. Additional iontophoretic treatment with Pikomed-Dention equipment was found more effective than topical NaF alone. Therapeutic use of iontophoresis could be employed in several other areas of dentistry. More attention should be paid to its use in caries prevention.
