ABSTRACT
PURPOSE:
The purpose of this study was to develop the radiographic technique for detecting the demineralization which is known as indication of dental caries MATERIALS ANDMETHODS:
This technique was based on the comparing of multiple radiographs which was irradiated by multiple X-ray spectra. For the meaningful comparing, the multiple radiographs were reconstructed to the dosimetrically consistent images using a standard material. The difference of resulting images of same target with multiple spectra represents the difference of response of material as regards the spectra.RESULTS:
We have found about 10% of demineralization of dental hard tissues particularly in the proximal region through the analyzing of differences.CONCLUSION:
Most intriguing thing in this investigation was that the method to analyze difference shows us to an anatomic structure of dental hard tissues even if absolute values of optical density were excluded during the procedures.
