Static measurement showed that fluorescence intensity increased with age in all six regions. However, the wavelength at maximum fluorescence or at full width of half maximum in the fluorescence emission spectrum, did not change ; the former and latter values were about 440 nm and 100 nm, respectively, in all six regions of all the teeth studied. Dynamic measurement suggested that auto-fluorescence at a wavelength of 440 nm had at least three components with different fluorescence decay times ; fast, intermediate and slow.<BR>The fluorescence intensities of these components increased with age in all six regions ; the intensity of the fast component increased in proportion to age after 18 years, while the rate of the increase in the fluorescence intensities of the other two components decreased with age. Changes with age in the ratio of the intensity of the three components to the static fluorescence intensities were distinguishable longitudinally; the ratio of the fast component increased with age in coronal dentin, while the ratio of the slow component decreased with age in dentin of the root apex. Cervical dentin showed a tendency intermediate between these two regions. These results indicate that patterns of changes with age differed in the longitudinal direction, which suggests that factors that affect age changes differ between coronal and root apex dentin."},{"@value":"ヒトの象牙質の頬舌と歯軸方向の6部位での自己蛍光強度の加齢的な変化を, 高速・時間分解・顕微蛍光測定装置を用いて検討した。静的な蛍光測定では, 蛍光強度はすべての部位で加齢に伴って増加した。動的な蛍光測定では, 蛍光スペクトルでピーク強度波長を示す440nmでの自己蛍光に少なくとも3つの蛍光成分の存在が示唆された。いずれの成分の蛍光強度も, すべての部位で加齢により増加したが, 増加の様子には差がみられた。蛍光の減衰速度が最も速い成分では, 蛍光強度が18歳以後加齢に比例して増加したのに対し, これより減衰速度の遅い他の2成分では, 蛍光強度の増加の度合が加齢とともにゆるやかになった。また, 静的な蛍光強度に対する3成分の蛍光強度の比率の加齢的な変化には, 歯軸方向で部位差がみられ, 加齢に伴い, 歯冠象牙質では減衰速度の最も速い成分の比率が増加したのに対し,
