Spotting the decay
The top left image shows a side-on view of a 3-mm thich section with simulated decay. The top image was taken using visible light transillumination and the decay cannot be seen. The bottom left image was taken using infrared transillumination and the decay is clearly visible. The bottom right is an X-ray where there is limited contrast between the enamel and the decay.
