Abstract : 「はじめに」 歯磨剤は, 伝統的な定義によれば, 『歯ブラシとともに用いられ, 歯ブラシが届き得るところの歯面を清掃するのに用いられる物質である』とされている. つまり, ブラッシングをする際に, 歯ブラシの補助材(剤)として用いられるものとする考え方である. 一方Hillは, 『歯磨剤はその殺菌性, 抗菌性, 抗酵素性あるいは中和性によってう蝕の発生を減少させ, または歯周病の抑制の助けになるような何らかの薬物または化学物質を混合した歯の清掃剤である』と述べている. 歯科における二大疾患である「う蝕」と「歯周疾患」は, プラーク中の微生物によって起こるものである. したがって, これらの予防には, 歯ブラシなどを用いての物理的清掃を行って歯面の微生物をコントロールすることが基本的手段となる. 歯ブラシだけによるプラーク除去率に比較して, 研磨剤が配合された歯磨剤を併用すると, その除去率は約30%も増すことが明らかになっている.

Abstract : [Abstract] Fluoride application is one of the most effective caries preventive measures. However, there are no reliable methods currently available in Japan to apply fluoride to early (low-aged) children as a caries preventive measure. Fluoride mouth-rinsing or fluoride dentifrice can not be safely used for younger children who can not rinse their mouth properly. Although caries reductions of about 60% in primary dentition with fluoride tablets and fluoride mouth-rinses have been reported overseas, these preparations are not currently available in Japan. In the present study, we studied a newly developed foam-type fluoride dentifrice by examining its properties and usage as well as oral sensations and fluoride levels in saliva after toothbrushing, and evaluated the feasibility of its use for caries prevention in infants. It was found that the fluoride in foam-type dentifrice had a higher diffusibility than ordinary dentifrice and soft paste-type fluoride dentifrice. Thus, when this foam-type dentifrice is used, higher fluoride is expected to be delivered to the oral cavity even after a brief brushing period. To adults, brushing with 0.2 g of the dentifrice and rinsing with 25 ml of water for 4 seconds only once are recommended. Since the survey of oral sensations revealed that the foam-type dentifrice had little influence on the sense of taste and showed little mucosal irritation, it was indicated that the dentifrice can be used without rinsing after brushing. Fluoride retention in saliva with time following toothbrushing with different kinds of fluoride dentifrice including foam-type dentifrice were examined. It was found that when the foam-type fluoride dentifrice was used, even in small amounts, fluoride levels in saliva were well maintained for a long time at more than 0.05 ppm, the lowest fluoride levels thought to inhibit demineralization of enamel. Assuming that these findings could be applied to infants and early (low-aged) children, the foam-type dentifrice would be recommended their parents as dentifrice for the second-brushing after the first-brushing with no dentifrice.
