Abstract:
PURPOSE: This study was done to know the usefulness of fractal analysis when evaluating the radiologic changes after decompression on jaw bone cystic lesions using fractal analysis. MATERIALS AND METHODS: 30cases of cystic lesions were followed up after decompression. Panoramic image was used to observe radiologic changes around the cystic lesion. The part of the panoramic image which showed radiologic change was defined as region of interest(ROI); The fractal dimension of the ROI was calculated using box-counting method. RESULTS: Using sign-rank test, there was a statistically significant difference in fractal dimensions after decompression therapy(P<;0.0001). The fractal dimensions statistically increased after decompression(the median of D:0.12). CONCLUSIONS: The ROI after decompression showed higher fractal dimensions which offer the objective proof of the bone healing around cystic lesions after decompression treatment.
