| 内容記述 | While dental whitening care is practiced very often lately, relapse can occur quite commonly. This might be mainly caused by the routine care as well as by extra-pigmen-tation on the enamel. It is suggested that the pigmentation on the enamel after whitening occurs during the progress of recalcification (alternative actions of decalcification and recalcification of the oral cavity). We examined the pigmentation on the enamel by recalcifying the teeth coated with a bleaching agent using a recalcified solution containing hematin pigments. As experimental materials for whitening and relapse, tablet-like sintered bodies (enamel disks) were prepared by baking enamel specimens of extracted human teeth and synthetic hydroxyapatite at 1200℃. Carried out in accordance with conventional methods, the sintered bodies were bleached with photocatalyst apatite, photocatalyst titanium oxide and Hi Lite^<[○!R]>. Hi Lite^<[○!R]> showed better results of bleaching action and a remarkably higher level of the intensity of the OH radical compared to photocatalytic bleaching agents. In spite of a lower level of the intensity of the OH radical, photocatalyst apatite showed a larger bleaching action compared to photocatalyst titanium oxide. When decalcified enamel specimens getting the large bleaching effect were immersed in a recalcified solution containing hematin pigments, hematin pigments and the distribution of Fe were observed at a depth of 7～10μm from the enamel surface. When there was strong whitening, there was a high positive correlation between the bleaching effect and "relapse". It is suggested that relapse occurs during the progress of recalcification due to various substances in saliva deposited on the enamel surface coarsened by whitening and decalcification. | |||||
