Abstract: Objective: To assess the initial effects of tooth ash in conjunction with platelet-rich fibrin (PRF) on reconstruction of bone defect. Methods: Ten white rabbits were selected to create an animal model with four defects on the skull. Defects in group A was used as vacant control, tooth ash particles were used solely in group B, tooth ash mixed with PRF were used in group C, and the defects in group D were filled with tooth ash combined with bone marrow. The animals were sacrificed 6 weeks later, bone samples were harvested for histological observation and statistical analysis. Results: The percentage of new bone formed in each group was 7.46%±2.21%, 17.61%±2.29%, 21.00%±4.73%, and 23.42%±3.22%, respectively. Group C and D showed a statistically greater amount of new bone formation compared with group A and B (P<0.05). No significant differences were found between group C and D. Conclusion: Teeth ash particle is a type of bone graft material with favorable biocompatibility and osteoconductivity. After in conjunction with PRF, it can facilitate the bone healing process in early stage.
