Thin-slices of human teeth were applied for the determination of ultraviolet absorption by using a microspectrophotometer (Zeiss UMSP type 1). The tooth tissue shows a non-specific ultraviolet absorption in a wide range of wave-length from 240 nm to 300 nm. The profile of spectra was different from that of nucleoprotein. The absorption spectrum in dentine was similar to that in cementum, but differ from that in enamel. The A_<260> and A_<280> show two or three times higher in dentine or enamel than those in cementum, respectively. A major part of ultraviolet absorbing substance in teeth seems to be extracted with a 5% of perchloric acid solution. A relative ultraviolet absorption value (A_<260> or A_<280> per unit area) distributed in different quantity relating to the tooth structure, whereas the value showed much higher in enamel than in dentine and lowest in cementum.
