“…There is no consensus in studies on how changes in FD value affect the trabecular meshwork in the alveolar bone structure. Contrary to some studies, 32,33 which show an increase in FD value in some diseases that cause osteoporotic effects; many studies have shown that the FD value decreases in systemic diseases 12,15,19,27,34–37 . In a study in which bone structure analysis was performed by computerized microtomography in cats with CKD; it has been shown that there is a lower bone volume in the trabecular bone 38 .…”

ObjectiveIn this study, we examined the mandibular trabecular bone structures by performing fractal dimension (FD) analysis in patients who underwent renal transplantation (RTx).MethodsOur study is an observational study with 69 RTx patients and 35 control group patients. The mean FD values of the patient and control groups were calculated and compared. In addition, biochemical parathyroid hormone (PTH), serum calcium, phosphorus, alkaline phosphatase (ALP), and vitamin‐D parameters and FD values of both groups were analyzed.ResultsFD values were significantly lower in the patient group than in the healthy group (p < .05). In the RTx group compared to the control group, ALP (90.71 ± 34.25–66.54 ± 16.8, respectively) (p < .001) and PTH (75.76 ± 38.01–38.17 ± 12.39, respectively) (p < .001) values were higher. There was a positive correlation between the FD values and ALP (rspearman = .305, p = .011) and a negative correlation between FD values and vitamin‐D (rspearman = .287, p = .017) of patients with RTx.ConclusionFD values were found to be lower in patients who underwent RTx compared to the control group. It should be considered that FD analysis can be a method that can be used to evaluate trabecular bone structure in patients undergoing RTx.

“…There are many recent studies related to bone quality through fractal analysis and dental radiology in the literature [9,11,12,30]. In the calculation of fractal dimension values, methods such as power, caliper and box counting methods are used [31]. It has been stated that the methods to be used in the analysis of mandibular and maxillary bones should differ.…”

Objective: In the literature, it is still unclear whether the trabecular structure of the jaw in subjects with hypodontia is different from those without hypodontia. Hence, the aim was to determine whether the mandibular trabecular bone structure of children and adolescents with hypodontia differs from the control group by using the fractal analysis method in this study.Materials and Methods: A total of 138 radiographs of 69 cases and 69 control subjects (mean age 13.2±10.1) were evaluated. The age and gender of subjects in the case and control groups were matched. Three regions of interest (ROI) were selected from the panoramic radiographs. Mann-Whitney U and Wilcoxon tests were used. p<0.05 was accepted for the significance value.Results: The mean fractal dimension (FD) values of ROI1, ROI2, and ROI3 were 1,25, 1,20, and 1,13, respectively. The means FD values obtained from the ramus region were higher than the other regions (p<0.05). The FD values did not differ significantly according to gender and age (p>0.05). The FD values of the case group were lower than the control group for ROI3 (p<0.05).Conclusions: The results of this study showed that the mandibular trabecular bone quality of pediatric patients with one missing tooth was different from the healthy group. The difference in the mean FD values from the ROIs indicates that the ramus has a denser structure than the mandibular corpus. Therefore, it shows that individuals with hypodontia may need additional procedures in cases that require orthodontic and implant treatment.Clinical Relevance: Clinicians should consider that individuals with hypodontia may need additional procedures in cases requiring orthodontic and implant treatment.

Class III malocclusion is a combination of dental and skeletal disorders that causes discrepancies in occlusion. Malocclusion can affect the structure of the Temporomandibular joint (TMJ) resulting in many problems, one of which is affecting the internal structure of the bone. This study aimed to examine the morphological features of class III patients’ trabecular structure of the mandibular condyle in comparison with normal class I individuals using fractal analysis (FA). To study the internal structure of the mandibular condyle bone, Computed Tomography (CT) scans of 45 severe class III patients (age: 16–46) who were the candidates for orthognathic surgery were selected and matched by age and sex with 45 normal class I individuals. The trabecular bone structure of the left and right mandibular condyles in three CT planes of the study group and control group were evaluated employing the FA. The result of the present study indicated that the fractal dimensions (FD) values of class III patients were lower than those of the normal class I individuals in axial (class I: 1.31 ± 0.02, class III: 1.28 ± 0.02), sagittal (class I: 1.25 ± 0.03, class III: 1.19 ± 0.08), and coronal (class I: 1.5 ± 0.06, class III: 1.45 ± 0.07) planes (P < 0.001). There were no significant differences between the FD values of the males and females. The intra-group evaluation revealed that there was no correlation between age and FD values. No evidence of laterality was found regarding the FD values of the right and left condyles. Given the noticeable differences between the FD values, it can be implied that severe class III malocclusion may affect the trabecular pattern of the cancellous bone of the mandibular condyle compared to class I individuals. Therefore, due to the altered trabecular structure, clinicians should be cautious when planning treatments for these patients.
