    Investigation of bone biomechanics in rats with traumatic kidney injury
    (Wolters Kluwer Medknow Publications, 2023) Nalbant, Asrin; Saygin, Duygu Akin; Aydin, Arif; Aydin Kabakci, Anil Didem
    Objective: Mineral metabolism disorders are common in chronic kidney disease (CKD) and increase the risk of fractures. It has been confirmed by animal models that these changes in bone also cause negative results in the mechanical properties of bone. Although there are many available methods for diagnosing metabolic bone disorders and estimating fracture risk, it has been suggested that biomechanical tests that provide information about bone's structural and material properties are most appropriate, particularly in small rodents with CKD. Therefore, this study aimed to investigate the effects of trauma-induced kidney damage on bone biomechanical properties. Materials and Methods: In this study, we used 16 adult Wistar Albino rats, 200-300 g, 4-5 months old. The animals were examined under two groups: kidney control (n = 9) and healty kidney control group and kidney damage group (n = 7). In the control group, the rats were fixed by laparotomy, and the kidneys were closed without suturing. However, the kidney damage group was approached by suturing. Results: When the bone biomechanical properties of the control and kidney-damaged groups were compared, a statistically significant difference was found between the displacement at maximum load, duration, and young's modulus groups (P < 0.005). Conclusion: The study showed that the bone biomechanical properties of rats with trauma-induced kidney damage changed, and there was an increased fracture risk.

    Morphometric Analysis of the Foramen Palatinum Majus by Cone-beam Computed Tomography
    (Galenos Publ House, 2023) Tassoker, Melek; Azman, Duygu; Aydin Kabakci, Anil Didem
    Objective: The aim of this study was to detect possible variations of the foramen palatinum majus (FPM), by imaging with cone-beam computed tomography (CBCT), and to make a morphometric comparison of FPM in dentate and edentulous individuals. Methods: In the study, CBCT recordings of 250 individuals, 125 dentate and 125 edentulous individuals, in the archive of the Faculty of Dentistry, Oral and Maxillofacial Radiology were retrospectively analyzed. The diameter of the FPM, its position relative to the molar teeth, its shape (round, ovoid, slit), its distance from the midmaxillary suture (MMS), and its distance from the incisive foramen NY, USA) was used for the analysis of the data and it was considered significant at the p<0.05 level. Results: The records of 122 female and 128 male patients aged between 18 and 86 years (52 +/- 16) were examined. In dentate individuals, FPM was most frequently located in the region between the second and third molars, 54.4% on the right and 56.8% on the left. The most common FPM shape was ovoid, with 80% on the right and 74.4% on the left. The diameter of FPM, FPM-MMS, and FPM-IF distance showed a statistically significant difference between dentate and edentulous individuals, and the values of edentulous individuals were higher (p<0.05). procedures in this region.
