“…[2][3][4][14][15][16][17] Considerable research has also been carried out to evaluate the mineral density of bones in various parts of the body, especially in patients with osteoporosis, and to examine the use of radiomorphometric studies in the diagnosis of osteoporosis. [18][19][20] In many of these studies, various parameters, which can be merged under the names of mandibular indices and mandibular cortical bone, were evaluated.…”

Objectives: The purpose of this study was to evaluate fractal analysis as a tool to quantitatively determine the mandibular trabecular bone changes in patients with chronic renal failure (CRF). Methods: In the present study, fractal analysis was performed using ImageJ (National Institutes of Health, Bethesda, MD) program with box-counting method over panoramic radiographs of 25 patients (14 females and 11 males) with CRF and 26 healthy individuals (14 females and 12 males) as a control group. The fractal dimension (FD) values of the patients and healthy individuals were compared. In addition, average biochemical parameters [parathyroid hormone (PTH), calcium (Ca), phosphorus (P), product of Ca and P levels (CaxP), alkaline phosphatase (ALP), vitamin D] of the patients with CRF, as measured during the 3 months before the panoramic radiographs, were compared with FD values. Results: According to the results, FD values of the patients with CRF were found to be statistically lower than the control group (p , 0.05). The average PTH levels of the patients with CRF were 416.16 ± 310.3 pg ml 21 ; average Ca levels were 8.94 ± 1.2 mg dl 21 ; average P levels were 5.76 ± 1.7 mg dl 21 ; average CaxP values were 51.12 ± 15.03; average ALP levels were 83.44 ± 36.8 U l 21 ; and the average vitamin D values were 19.43 ± 9.7 ng ml 21 . In addition, there was no significant correlation between FD values and the biochemical parameters of the patients, and there was no correlation between age, gender and FD. Conclusions: The FD values of the patients with CRF were lower than those of the controls. This finding suggests that FD analysis might be a promising simple and cost-effective tool for evaluating trabecular bone structure.

“…FA has been used for image analysis of trabecular bone structure of patients with osteoporosis, hyperparathyroidism and implant planning. 13,[22][23][24][25][26][27][28] In a radiography study on the relationship between periodontal disease and bone destruction, it was reported that the destructive effects of periodontal pathology on trabecular bone can be successfully evaluated with FA. Researchers have stated that even small trabecular destructive changes in the early stages of the disease can be determined by FA before the effects of periodontal pathology are clearly emerged.…”

“…De Molon et al [11] evaluated for the first time the pattern of bone remodeling in sinus lifting in human biopsies using autogenous bone graft by means of FD and histological analysis. Zeytinoğlu et al [12] reported that trabecular bone around successful dental implants exhibits lower FD values 6 months after prosthodontic loading and displays stable bony microstructure at the 12-month follow-up point. Bianciardi et al [13] found that parameters based on a combination of ultrasonic examination and fractal analysis on radiographic images may add useful structural information regarding the patient's skeleton using noninvasive procedures.…”

Rheumatoid arthritis (RA) is a chronic and systemic inflammatory disorder. Conventional radiography, a widely available and cost-effective examination method, remains the standard of reference for the detection and quantification of joint involvement in RA. Fractal dimension (FD) of the trabecular bone structure has been proven to correlate with the bone's physical properties. The present study was designed to use fractal analysis to validate radiograph changes in the hand of RA patients.This study retrospectively evaluated the hand radiographs of 108 subjects. Fifty-four patients were suffering from RA, of which 18 were men and 36 were women. Their ages ranged from 25 to 90 years. The hand radiographs of 54 healthy patients, 18 men and 36 women (age range 23–88 years), were used as the control group. Bone structure value (BSV) is a critical parameter for the assessment and analysis of bone microarchitecture. The BSVs were calculated over the fractal dimension using the Brownian motion.The BSV calculated for ROI showed a significant difference in ROI5 (0.210 ± 0.045), ROI6 (0.186 ± 0.066), and ROI11 (0.201 ± 0.056) in patients with RA, in comparison to the CG (P < 0.05). A significant correlation was observed between anti-CCP and ROI4, ROI5, ROI6, ROI9, and ROI12 in seropositive RA patients (post hoc test (Bonferroni) P <0.001).This study demonstrates that the bone textural image analysis technique can be used to quantify the radiographic changes in RA hands, based on comparisons of FDs.
