Abstract (original English)

Purpose To investigate the efficacy of chitosan and calcium carbonate (CaCO₃)-based scaffolds in promoting bone regeneration in preclinical in vivo models, focusing on bone volume, mineral density, histological outcomes, and biomechanical properties. Methods This systematic review adheres to PRISMA guidelines. A comprehensive search was conducted across PubMed, Web of Science, Scopus, and Cochrane Library for studies published from March 2015 to March 2025 using keywords such as "chitosan," "calcium carbonate," "bone regeneration," and "scaffolds." Eligible studies involved preclinical in vivo research on bone defect repair with chitosan or calcium carbonate scaffolds. Studies were included if they compared these scaffolds with other bone regeneration materials or no intervention. The methodological quality of the studies was assessed using the SYRCLE Risk of Bias tool. Results Thirty preclinical in vivo studies involving 850 animals were included. Chitosan scaffolds showed new bone formation ranging from 40% to 85%, while calcium carbonate scaffolds showed regeneration rates between 50% and 70%. Significant improvements in bone mineral density (BMD), bone volume-to-total volume ratio (BV/TV), and trabecular thickness were observed in scaffold-treated groups. Histological findings indicated increased osteoblast activity, mineralization, and vascularization, especially in chitos
