ClinConnect Summary

The fractal dimension analysis of each radiograph was performed using the box-counting method proposed by White and Rudolph \[1\] (Figure 1). All periapical radiographs in high resolution Jpeg format to be included in the study was converted to tagged image file formats (TIFF). Each ROI at 18 x 19 pixels and 2 mm from the radiographic apex was selected, cropped and amplified. "Gaussian Blur" was used to eliminate the brightness changes due to soft tissues and variable bone thicknesses. The resulting image was then be subtracted from the original image. Bone marrow spaces and trabeculae were...
