“…Both of these findings were consistent with the study conducted by Arsan et al [ 8 ], wherein although the fractal value of the right side in the case group was less compared to the control group, it was not statistically significant and there was a statistically significant difference on the left side supporting the present study. It was also in line with the study conducted by Yesiltepe et al [ 16 ] on patients with rheumatoid arthritis of TMJ in which there was a statistically significant difference between the case and the control group on the right side. Also, the fractal findings were supported by the studies conducted by Gumussoy et al [ 17 ] and Jayachandran et al [ 18 ] done on digital panoramic radiographs in patients with chronic renal failure and rheumatoid arthritis.…”

Introduction Fractal analysis has proved to be a salient tool to quantitatively assess the qualitative changes in the bone trabeculae of patients with hyperparathyroidism, osteoporosis, and various temporomandibular disorders, including osteoarthritis (OA) and rheumatoid arthritis of temporomandibular joint (TMJ), in several previous studies. The purpose of this study was to use fractal analysis to assess alterations in the trabecular pattern of the mandibular condyle in patients with degenerative temporomandibular disorders. Materials and methods This study comprised 98 subjects with 49 subjects in the study group and 49 subjects in the control group, aged 18-50 years. Age and sex in the control group were matched to those in the case group. The subjects were assessed clinically with the Diagnostic Criteria for Temporomandibular Disorders. Digital panoramic X-ray equipment with set parameters of 70 kvp, 8 mA, and 16-second exposure duration was used to take panoramic radiographs. Fractal analysis was done and the calculated fractal dimension value was obtained using ImageJ version 1.48 software (National Institutes of Health, Bethesda, MD). The same observer used Muir and Goss's method to rate the total degenerative changes in the condylar surfaces, which were substantiated by the calculated fractal dimension value. The data were statistically analyzed. Results The results revealed a significant difference (p-value = 0.041) between the mean fractal value in the case group's (1.35) and the control group's (1.38) left sides whereas the differences in the mean fractal values between the case and control groups on the right side was not significant (p-value = 0.49). Conclusion It is recommended to use the fractal dimension value and the total degenerative severity score together to quantify degenerative changes in the TMJ OA rather than exclusively relying on fractal value.

“…The FA method has been used in previous studies for the analysis of trabecular microstructure in periodontal disease, osteoporosis, and implant planning. 20 – 23 In a study-related periodontitis and alveolar bone loss, Updike and Nowzari 8 reported that the destructive effects of periodontitis on trabecular bone may be successfully evaluated with FA method. Jett et al 24 stated that even small destructive changes on trabecular bone in the early stages of pathology may be determined by the FA method before the effects of periodontal destruction are emerged.…”

Objective: The basis of the research is the application of fractal analysis (FA) to panoramic radiographs of patients with primary hyperparathyroidism (PHPT). In addition, the relationship between the relevant biochemistry parameters and fractal values of healthy controls and patients with PHPT will be evaluated. Materials and Methods In the current study, FA was performed with ImageJ program on panoramic radiographs of 48 patients diagnosed with PHPT. Fractal dimension (FD) values of the patients and 48 healthy subjects were compared. In addition, biochemical [parathyroid hormone (PTH), serum calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), and vitamin D] parameters and FD values of both groups were analyzed with Mann–Whitney U -tests and Pearson correlation coefficient ( P < .05). Results FD values of four different angular areas were significantly lower in the patient group than in the healthy group ( P < .05). There was no statistically significant difference between the patient and control groups in the measurements between the apexes of the right and left premolar and molar teeth. The mean PTH, Ca, P, and vitamin D values of the patients with PHPT and control group were highly significant, and all the parameters of the patient group showed higher values than the control group except for the P values ( P < .001). In the patient group and control group, there was no significant difference between mean ALP values ( P = .48). No correlation was found between the two groups. Conclusion Bone biopsy is the gold standard method for the diagnosis of bone structure changes in patients with PHPT. However, it is not used routinely because it is an invasive method. The FA method applied to panoramic radiographs may be used as a noninvasive, easy-to-apply method to reveal the changes in the trabecular structure of the jaw bones of the patients.

“…Araştırmacılar bu hastalıkların kemik kalitesi üzerindeki olumsuz etkileri ve bunların erken teşhisiyle ilgili bir hayli çalışma yapmıştır. [4][5][6][7][8][9] Kemik kalitesi; trabeküler devamlılık, kemik geometrisi, kemikte oluşmuş olan mikrohasarlar, kemik dokunun mimarisi, mineralizasyon miktarı ve kusurları gibi birçok faktöre bağlıdır. Kemik yapının analizinde geçmiş yıllarda sıklıkla kemik mineral yoğunluğu ölçümü kullanılmaktaydı.…”

Amaç Bu çalışmanın amacı aynı çenenin farklı röntgen cihazları ve ekspozür parametreleri ile elde edilen dental panoramik radyografileri (PR) üzerinde aynı ilgi bölgesi için yapılan fraktal analiz (FA) sonuçlarına cihazların ve teknik faktörlerin etkisini incelemektir. (Sakarya Tıp Dergisi 2019, 9(3):492-498) Gereç ve Yöntemler Bu çalışmada 15 adet koyun hemimandibulasının iki farklı röntgen cihazı ve değişik ekspozür parametreleri ile elde edilen 45 panoramik röntgen görüntüsü kullanıldı. ImageJ (National Institutes of Health, Bethesda, MD) programı kullanılarak kutu sayma yöntemi ile PR'ler üzerinde mandibular trabeküler kemiğin FA'sı yapıldı. Sonuçlar Paired t-testi kullanılarak istatistiksel olarak değerlendirildi. Bulgular 15 adet koyun hemimandibulasının 1. Panoramik röntgen cihazında 57 kVp, 5 mA ve 63 kVp, 6 mA parametreleri ile çekilen panoramik görüntülerinde elde edilen ortalama fraktal boyut (FB) değeri 1,3551 ve 1,3653 idi. Yine aynı parametreler ile 2. cihazdan elde edilen ortalama FB ise 1,3632 ve 1,3698 idi. Her iki röntgen cihazı ile yapılan çekimlere ait FB değerleri arasında istatistiksel olarak anlamlı bir fark yoktu (p=0,552), (p=0,714). 1. Cihaz ile yapılan 1. ve 2. çekimlere ait FB değerleri arasında ve 2. cihaz ile yapılan 1. ve 2. çekimlere ait FB değerleri arasında istatistiksel olarak anlamlı bir fark yoktu (p=0,164), (p=0,587). Sonuç Aynı çenenin farklı röntgen cihazı ve tüp voltaj değerleri ile çekilen PR'leri üzerinde aynı ilgi bölgesinden elde edilen FB değerleri farklı olmakla beraber, FB değerlerindeki değişimler sonuçlarda istatistiksel olarak anlamlı bir fark oluşturmamıştır.
