Özet
Aim: This study aimed to evaluate the osteogenic effects of systemic metformin and exenatide administration on bone tissue regeneration in an experimental rat model by utilising micro‑computed tomography (micro‑CT) and histological analysis. Materials and Methods: Uniform craniotomy defects measuring 3 mm in diameter and 2 mm depth were performed in the parietal bones of 27 female albino Wistar rats, which were randomly divided into three groups: 1) a group receiving 100 mg/kg/day of oral metformin, 2) a group receiving 3 μg/kg/day of intraperitoneal exenatide, and 3) a control group receiving no medication. Bone volume and density at the defect site were evaluated using micro‑CT scanning and analysis. Results: Bone regeneration and the integration of newly formed bone into intact bone were assessed through histological and immunohistochemical examinations. In all three groups, the results showed no significant differences in bone volume, bone density, the presence of fibrous connective tissue, or the complete integration of the defect area into the bone tissue. However, the experimental groups exhibited significant differences in the number of osteoblasts (P = 0.007) and osteoclasts (P = 0.007) when compared to the control group. Conclusions: Metformin and exenatide enhance the activity of osteoblasts and osteoclasts in bone defects, promoting osteogenic potential during the healing process in non‑diabetic rats. © 2025 Journal of Oral and Maxillofacial Pathology.
