ABSTRACT:

The only symptom of chronic inflammation of the periapical tissues are periapical changes visible on radiographs. The damage is visible as the inflammation reaches the cortical plates. The lesions located in the cancellous bone are not easily visible on the radiograph. The advancement of computer technology in radiography, which has many advantages and appears on the market, is encouraging clinicians to use this technology. It has additional image processing software such as the color spectrum. Most of the systems available today can convert the colors of images to grayscale. People can distinguish between many more colors than shades of gray. The aim of this study was to compare the diagnostic efficacy of conventional radiography, and digital radiography with color conversion in diagnosing the periapical lesions located in cancellous bone. Place and Duration: In the Department of Endodontics, Nishtar Institute of Dentistry, Multan for six months duration from January 2020 to June 2020. Methods: 10 premolars were placed in the bony sections of the mandible. Conventional X-rays were taken to ensure that the slices had not previously seen any periapical changes. In the next stage, simulated periapical changes in the cheek or lingual spongy bone were artificially prepared. Then, direct and indirect conventional and digital photos were taken. The digital black and white images have been converted to color images using an image processing system. Five observers were asked to determine the presence, location and size of the lesions. Results: Statistical analyzes showed that color conversion in digital radiography is more accurate than in black and white digital and conventional radiography in determining the presence, location and size of lesions. Conclusion: In conclusion, converting gray values of digital images to a color spectrum can improve bone loss detection. It is a useful tool for diagnosing cancers of the cancellous bone. Keywords: digital radiography, bone damage, color spectrum.
