Is there better software for caries analysis on the horizon?

Researchers at RMK Engineering College in Tamil Nadu have discovered a way to analyze pixel densities in dental radiographs. This may lead to more accurate caries diagnosis. From an overview on Medical News Today:

The researchers at RMK engineering college have now developed an X-ray image analysis technique that reveals the pixel intensities at different X-ray wavelengths, much like the histogram analysis of images by a high-specification digital camera. Siva Kumar explains 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. The researchers found that in the X-ray histogram the pixel intensities are concentrated in different ranges depending on degree of decay.
