Siva Kumar says that the software reveals that the X-ray histogram and spectrum are very different depending on whether the teeth X-rayed are normal or exhibiting the early stages of decay.
In the X-ray histogram, the pixel intensities are concentrated in different ranges depending on degree of decay, he adds.
He believes that dental clinicians may find this technique very useful, and that it may be extended using neural networks to automatically identify the different stages of dental caries.
