“…FD analysis, a mathematical method used for the measurement of complex structures such as trabecular bone, has long been used in the evaluation of changes in bone structures in various systemic diseases and can be applied to DPR. [10][11][12][13][14]17 No previous studies used FD analysis to investigate the changes in trabecular bone patterns resulting from orthodontic treatment. Despite ample research together with recent reports indicating that FD analysis successfully demonstrates changes in trabeculae, the continuing lack of consensus on the effects of functional appliance treatment prompted this study of a new method with which to investigate the changes in mandibular trabecular structures resulting from functional appliance treatment.…”

“…The use of the FD analysis method has been shown to be suitable for assessing bone on panoramic radiographs, in the diagnosis of systemic diseases such as thalassemia and diabetes, and in many sensitive conditions, such as the postoperative evaluation of bone healing. [11][12][13][14] Although previous studies have reported high reliability of this analysis, it may be beneficial to conduct future studies using threedimensional images.…”

“…9 One of the evaluation methods available is fractal dimension (FD) analysis, a mathematical method used to measure and assess complex structures such as trabecular bone. [10][11][12] In FD analysis, the trabecular bone pattern is evaluated using a box-counting algorithm that quantifies the bone marrow and trabecular bone interface. A higher FD value indicates a more complex bone structure.…”

Objective To evaluate the effects of functional appliance treatment on mandibular trabecular structure using fractal dimension (FD) analysis of dental panoramic radiographs. Materials and Methods This study was conducted using digital panoramic radiographs of 45 patients with Class II malocclusion treated with functional appliances (treatment group, mean age: 11.39 ± 0.97 years; 23 girls, 22 boys) acquired before (T0) and after (T1) treatment and the panoramic radiographs of 45 control subjects who had undergone no orthodontic treatment (control group, mean age: 11.31 ± 0.87 years; 23 girls, 22 boys). FD values in the condylar process, mandibular corpus, and mandibular angle were analyzed from the panoramic radiographs of both groups. Results Analysis of changes in FD between T0 and T1 revealed significant increases in the FD values of the right and left condylar processes and right mandibular corpus in the treatment group (P < .001) and in the right condylar process in the control group (P < .05). Between-group comparisons demonstrated that the treatment group showed greater changes in the condylar process (right, P < .001; left, P < .05) and right mandibular corpus (P < .05) compared to controls. Correlation analysis between the cephalometric and FD changes in the treatment group showed the right condylar process changes were negatively correlated with GoGn/SN angle (P < .05) and positively correlated with Co-Go (P < .05), although these correlations were weak. Conclusions FD analysis demonstrated significant changes in trabeculation of the condyle and mandibular corpus in the treatment group compared to the control group. Functional appliance treatment may lead to skeletal correction by altering skeletal form and trabeculation of the mandibular bone.

“…Recent studies have shown that AIs significantly reduce the levels of estrogen and affect the periodontal health of BCa patients and reduce saliva flow, thereby affecting oral health‐related quality of life 8–10 . There are also studies reporting that the AIs therapy can cause bone fractures, skeletal system pathologies, and a reduction in trabecular bone volume 11–13 . Hong et al reported that Long‐term AI therapy negatively effect bone quality and bone mineral density (BMD) 12 …”

AimTo study the dental and periodontal status of women with breast cancer (BCa) having tamoxifen or aromatase inhibitors (AIs) treatment in comparison with control healthy women.MethodsFifty‐one women on tamoxifen therapy, 52 women on AIs therapy and 52 systemically healthy controls were included in the study. The total number of teeth, the number of teeth indicated for extraction, the number of decayed teeth, and the duration of medication were recorded. Periodontal status was evaluated with gingival index (GI); plaque index (PI); bleeding on probing (BOP); probing depth (PD) and clinical attachment loss (CAL).ResultsThe lowest number of teeth and decayed teeth was found in AIs users (P < .001 and P = .003 respectively). The highest CAL value was seen in AIs users (P = .042) whereas no significant difference was found between the groups in terms of PI, GI, and PD (P = .102, P = .233, and P = .306, respectively). Lower PI was observed in patients using AIs for less than 2 years (P = .048).ConclusionsWhile tamoxifen did not affect the dental and periodontal condition, AIs medication adversely affected the dental and periodontal condition by more tooth loss and higher CAL.

Andrade NS. Post-extraction socket healing in subjects with chronic renal failure undergoing hemodialysis [thesis]. São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2018. Versão Original. Chronic kidney disease is the metabolic disorder resulting from progressive and irreversible decline of the renal function. The final stage of this disease is known as chronic kidney failure (CKF) that demands the start of renal replacement therapy, usually hemodialysis (HD). The clinical management of people with CKF can represent a challenge for dentists, especially when performing invasive dental procedures. Despite the lack of studies and clinical or scientific evidences that investigate the risk of post-extraction complications in people with CKF, several authors still recommend that dentists prescribe the use of prophylactic antibiotics to these individuals. Thus, our study aimed to assess clinically and radiographically the process of post-extraction socket healing in individuals with CKF submitted to HD, comparing to a control group without CKF, without the prescription of the prophylactic antibiotic. It was a prospective observational study that included 48 individuals with CKF in HD to compose the study group (SG) and 29 control subjects without CKF to form the control group (CG). The same dentist applied the questionnaire on medical history of the patient, conducted the clinical odontological exam and requested laboratory tests (hemogram, coagulogram, urea, creatinine, total calcium, alkaline phosphatase and parathyroid hormone). All participants were submitted to exodontia of erupted teeth, always by the same dental surgeons, without the use of prophylactic antibiotics, during the period from October 2016 to December 2018. Postoperative assessments were conducted 3, 7, 21 and 60 days after the extractions. On the SG, teeth extractions were performed in 65 distinct surgical times, totaling 87 extractions. On the CG, 76 extractions were performed in 36 surgical times. In SG there was a significant delay in surgical wound epithelization, which is observed 21 days after exodontia (29.9% versus 3.9%, p <0.001) and 2 hemorrhagic complications. We did not observe complications of infectious origins in any case for any group. The delay in alveolar epithelization on SG was significantly associated with a lower neutrophil count and wider HD time (p <0.05). Presence of bone spicules, 21 days after exodontia, was associated with lower values of serum calcium (p <0.05). In the radiographic evaluation of SG subjects, we observed a decreased bone density measured by the intensity of pixels and a lower complexity of the bone structure at the fractal dimension 60 days after exodontia, when compared to CG (p <0.001). We concluded that alveolar repair after extractions in individuals with CKF undergoing HD is similar to controls, with only a delay in the epithelization of the surgical wound that did not impact on the final repair of the alveolus. We can expect in some cases the occurrence of hemorrhagic events in individ...
