||Tooth staining is not detrimental to dental health, but it is a dental problem that occurs frequently. Teeth with coloring problems do not give a healthy impression. The mechanism of tooth staining should be clarified to resolve this embarrassment, but much remains unknown. Tannin is a pigment found in various plants and is known in food and drink as the pigment component of persimmons and wine. In this study, we experimentally stained enamel, which constitutes the superficial layer of the crown of teeth, by reacting with tannin and analyzed the results both visually and digitally, and observed whether the microstructure changed or not, and discussed the relationship with the reaction time.
