Autofluorescence signals
All cusps and the denticles from inner lateral teeth emitted a strong
green autofluorescence signal on their anterior and posterior surfaces,
i.e., they emitted a strong signal after excitement with the 488 nm
laser. The cusps’ lateral surfaces, the tooth styli and bases appeared
rather red- to yellow-brown, i.e., emitted a strong signal after
excitement with the lasers of 555 and 639 nm wavelength (see Figure 4).
The bulges and bases of the teeth exhibited a strong blue signal, i.e.,
emitted a strong signal after excitement with the 405 nm laser).
