Description

The study was conducted by the double-blind method to determine the clinical effects of an iontophoretic toothbrush used with a sodium fluoride dentifrice of 29 patients of cervical hypersensitivity during 6 weeks experimental period. The following results were obtained. 1) The clinical effect (reduction hypersensitivity) of iontophoretic toothbrush was significantly different from that of placebo group after 2 weeks (P<0.01) and it was highly significant difference (P<0.001) after 6 weeks. In the active group the reduction in sensitivity, after 6 weeks was shown to be 60.6% and in the placebo group 25.4%. 2) Fifty point one per cent of the initially sensitive teeth had lost all sensitivity after 6 weeks. 3) No side effect of this iontophoretic toothbrush was observed, during the experimental period. On the basis of the above facts, it is concluded that an iontophoretic toothbrush used with a fluoride dentifrice is highly effective in the cervical hypersensitivity. Accordingly, the use of an iontophoretic toothbrush is simple and available method for home dental care.
