Aim Garre's osteomyelitis is a local thickening of the periosteum caused by a slight irritation or infection. We aimed to present the extraoral, intraoral, and radiographic findings and postoperative pursuits of two patients diagnosed with Garre's osteomyelitis. In this case report, although clinical findings indicate infection source, these clinical findings are strongly supported by cone-beam computed tomography images. In addition, it can be seen that when we have followed the case I, we have chosen the right path in treatment. Case Reports Two patients presented to our clinic due to severe swelling and facial asymmetry in the right and left mandibular region. As a result of the clinical and radiological examinations, the patients were diagnosed with Garre's osteomyelitis. Infected teeth that were responsible for the formation of Garre's osteomyelitis were extracted under antibiotic treatment in both cases. A complete improvement in postoperative control was observed in case I. On the other hand, the other case could not be followed up postoperatively. Conclusion In Garre's osteomyelitis, new bone formation can occur in many pathological conditions. Therefore, it should be distinguished from other pathologies that cause new bone formation, such as Ewing's sarcoma, Caffey disease, and fibrous dysplasia.
Background/aim: It is believed that radiotherapy has important effects on oxidant/antioxidant systems. Oxidative stress occurs when the balance between oxidant formation and antioxidant defense is disrupted in favour of oxidants. The aim of this study was to determine the biochemical changes in saliva pre-and post-radiotherapy in head-neck radiotherapy patients and to find out the effects of radiation on glutathione (GSH), glutathione peroxidase (GSH-Px), and Malondialdehyde (MDA) levels in saliva. Materials and methods: This study included 16 patients undergoing head-neck radiotherapy in the Atatürk University Research Hospital. The levels of GSH, GSH-Px, and MDA were measured in saliva samples taken from the patients pre-and postradiotherapy. The same biochemical parameters were also measured in saliva samples from 30 healthy individuals who did not undergo head-neck radiotherapy. The data obtained were analysed using the paired t-test and the Mann-Whitney U test. Results: When the levels of GSH (p > 0.05), GSH-Px (p > 0.05), and MDA (p < 0.05) in saliva were compared pre-and post-radiotherapy in the patient group, the only significant increase was detected in MDA level post-radiotherapy. When the pre-and post-radiotherapy levels of saliva GSH (p < 0.01, p < 0.001, respectively), GSH-Px (p > 0.05, p < 0.05, respectively), and MDA (p < 0.01, p < 0.001, respectively) were compared with those of the control group, it was revealed that the GSH level significantly lower and the MDA level was significantly higher in both pre-and postradiotherapy compared to the control group. Also, only the post-radiotherapy saliva GSH-Px level was found to be significantly lower than the control group. 2 Conclusion: These findings show that the changes in saliva GSH, GSH-Px and MDA levels in patients with head-neck malignity intensified due to radiation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
