Effect of Iontophoretic Toothbrush on Cervical Hypersensitivity イオン導入電気歯刷子応用による象牙質知覚過敏症への効果 太田, 紀雄 秋田, 有一 加藤, 世一 芦沢, 千洋 平林, 秀俊 篠原, 昭夫 application/pdf 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. journal article 松本歯科大学学会 1979-12-31 VoR application/pdf 松本歯学 2 5 191 199 AN00232590 0385-1613 https://mdu.repo.nii.ac.jp/record/233/files/matsumoto_shigaku_05-02-09.pdf https://mdu.repo.nii.ac.jp/records/233 jpn
